Material Identity & Engineering Data
Grade 2 / UNS R50400 is commercially pure titanium with controlled interstitial and residual elements. Engineering data should be read according to its source: specification requirement, producer reference or actual heat / lot test result.
Commercially Pure Titanium
Grade 2 is the industrial balance point in the CP titanium family.
UNS R50400Grade 2 combines moderate strength with useful ductility, formability, weldability and the corrosion behaviour expected from commercially pure titanium.
Within CP titanium, oxygen, iron and other interstitial or residual elements influence strength. Higher levels generally increase tensile and proof strength while reducing elongation.
Material Logic
Grade 2 should be selected as a CP titanium grade in its own right, not treated as a lower-strength version of Grade 5.

Grade 2 Titanium · Corrosion Service
Corrosion Resistance & Service Envelope
Grade 2 titanium depends on a stable titanium-oxide passive film for corrosion resistance. The material should be reviewed against the actual medium, concentration, temperature, pH, redox condition, flow, crevice geometry and fabrication condition.
Why Grade 2 Works
Grade 2 performs well when the passive film remains stable. Service review begins by asking what supports — or disrupts — that passive condition.
Common selection areas
Common engineering use does not replace condition-specific review.
01
Seawater & Marine Cooling
Commercially pure titanium is widely selected for seawater systems where the oxide film remains stable.
02
Neutral Chloride Media
Many neutral chloride environments are favourable, while temperature, concentration and crevice geometry still matter.
03
Oxidizing Service
Oxidizing conditions generally support formation and maintenance of the protective titanium-oxide film.
04
Wet Chlorine Environments
Moisture-containing chlorine must be distinguished from dry-chlorine service when reviewing titanium suitability.
Review Before Release
Conditions that can move Grade 2 outside its comfortable service envelope
These conditions should trigger a service-specific material review before the purchase specification is released.
Reducing Acids
Low-redox or strongly reducing acid conditions can reduce passive-film stability; concentration and temperature matter.
HF / Fluoride
Fluoride-containing environments are a high-risk corrosion route for titanium and require separate evaluation.
Oxygen-Depleted Crevices
Restricted oxygen renewal together with elevated temperature or concentrated chloride can increase crevice-corrosion susceptibility.
Dry Chlorine / Hot Alkali
Dry chlorine and high-temperature concentrated alkali should not be treated as extensions of normal wet-chlorine or seawater service.
For service review, provide: medium · concentration · temperature · pH · oxidizing/reducing state · flow · crevice geometry · weld/fabrication condition
Grade 2 Titanium · Heat Transfer & Seawater
Heat Exchanger, Condenser & Seawater Systems
Grade 2 titanium is widely specified for condenser, heat-exchanger, desalination and seawater-cooling equipment. The procurement route depends on whether the requirement is heat-transfer tube, flat product, general pipe or a drawing-based fabricated component.
Why Grade 2 enters heat-transfer equipment
The commercial case is not “high thermal conductivity.” Grade 2 is selected because corrosion resistance can support thin-wall heat-transfer construction, seawater service and long equipment life when the product route and operating conditions are correctly specified.
Heat-Transfer Tube
Condenser / Evaporator / HX Tube
ASTM B338Heat-exchanger and condenser tubing follows a dedicated tube route. OD, wall, length, manufacturing route, inspection and documentation should be confirmed as one tube order.
Heat Exchanger Tubes →Flat Product Route
PHE Plate / Fabricated Flat Product
ASTM B265Plate and sheet provide the starting flat-product route for formed heat-transfer plates and other fabricated components. Finished geometry and forming requirements belong to the component drawing.
Titanium Plate & Sheet →Pipe / Fabricated Route
Seawater Pipe & Drawing-Based Parts
B861 / B862 where pipe is specifiedGeneral seamless or welded pipe is a different procurement route from B338 heat-transfer tube. Tube sheets, cut parts and machined pieces must also trace back to the identified base material route.

03
Titanium Substrate
Titanium can be supplied as the structural substrate for an electrochemical component when the drawing and processing route are defined.
Scope Boundary
Catalytic coating, electrode activation and complete process equipment are separate scopes and are not implied by Grade 2 base-material supply.
Engineering Routes

Grade 2 Titanium · Fabrication Engineering
Forming, Welding & Machining Grade 2
Grade 2 is workable, but the drawing still needs to account for rolling direction, anisotropy, springback, tool contact, shielding, cleanliness, contamination risk and the final machining route. Fabrication quality comes from process control rather than a generic “easy to fabricate” claim.
Commercially pure titanium can be cold-bent and press-formed. Rolling direction, planar anisotropy, springback and contact friction should be considered in bend radii, die design and repeatability.
- Rolling Direction
- Springback Allowance
- Deep Drawing
- Lubrication
- Galling Control
02 · Welding
Clean joint. Controlled inert shielding.
GTAW / TIG and GMAW / MIG are established titanium welding routes. The molten weld, cooling weld metal and root side must receive the shielding appropriate to the joint and process. Clean surfaces, filler and work areas are critical because hot titanium is sensitive to air and moisture contamination.
O / N / H contamination can harden or embrittle titanium. ERTi-2 welding filler and ASTM B863 Grade 2 base-metal wire are separate product classifications.
03 · Machining
Control heat, contact and finished tolerance.
Machining requirements should be quoted together with the starting material form and final tolerance. Stable tooling, positive cutting action, suitable coolant or lubrication and heat control help protect surface condition and tool life.
Cut edges or surfaces affected by thermal processing may need additional finishing before the component is released.
Rolling Direction
Critical bends and formed geometry should retain the required orientation information where direction affects response.
Springback & Tooling
Die allowance and dimensional compensation depend on geometry, thickness, material strength and forming method.
Galling & Lubrication
Titanium can gall against tooling, so tool contact and lubrication should match the forming or machining operation.
Thermal Condition
Annealing or stress relief is not a universal Grade 2 default; use it only when the product route, process or order requires it.
Grade 2 Titanium · Delivery Condition & Surface
Condition, Surface Finish & Secondary Processing
A Grade 2 RFQ should separate material condition, surface finish, roughness and secondary processing. Terms such as annealed, pickled, ground or machined describe different parts of the delivery specification and should not be used interchangeably.
Write the RFQ in separate layers
Condition is not the same thing as surface finish.
Define each requirement separately so the mill route, processing scope and quotation can be compared correctly.
Condition
Annealed · Stress Relieved when applicable · Other specified product condition
Condition follows the product form, specification and actual processing route.
Surface
Descaled · Pickled · Blasted · Peeled · Ground · Polished
ASTM B600 provides cleaning and descaling guidance; it does not make “passivated” a universal Grade 2 delivery state.
Processing
Cut-to-Size · Waterjet · CNC · Chamfering · Drawing-Based Machining
If surface roughness matters, specify the required Ra separately from the finish name.
RFQ Delivery Language
Specify the finish, not just “Grade 2”.

Grade 2 RFQ Desk & Buyer FAQ
A quote becomes faster and more comparable when the product form, specification, dimensions, condition, inspection scope and commercial quantity are defined together. The items below are the information normally needed to release a Grade 2 quotation.
Buyer FAQ
Six questions that commonly affect quotation release
01 Can you confirm stock or production availability for my Grade 2 size and quantity?
Availability is confirmed against the actual product form, dimensions, quantity, condition and required processing or testing. Ready stock should only be stated after the requested size and quantity are checked.
02 What affects Grade 2 titanium price, MOQ and lead time?
Product form, dimensions, tolerance, quantity, manufacturing route, surface or machining requirements, inspection scope, certification and destination can all affect price, MOQ and production lead time. These values should be confirmed with the actual RFQ rather than treated as fixed catalogue values.
03 What inspection documents and material records can be supplied?
Chemistry, mechanical results, heat or lot traceability and applicable inspection records can be reviewed against the selected product standard and purchase order. EN 10204 3.1, additional testing or third-party inspection should be specified when required and confirmed with the quotation.
04 What is the purchasing difference between Grade 2 and Grade 2H?
Grade 2 and Grade 2H use UNS R50400, but the H-grade route carries a higher specified minimum tensile requirement where the applicable product standard recognizes it. Grade 2H should therefore be ordered and certified through the applicable H-grade requirement rather than inferred from a single tensile result.
05 Can TA2 or JIS Class 2 be substituted directly for ASTM Grade 2?
They may be used as cross-reference designations during material discussion, but they should not be treated as automatic substitutes. The target product standard, chemistry, mechanical requirements, condition and product form should be checked before substitution.
06 Does Grade 2 titanium automatically comply with ASTM F67?
No. Grade 2 identifies a titanium material grade, while ASTM F67 is a specific specification route with its own scope and requirements. F67 must be specified and verified when that compliance route is required.
