Specification Requirements
ASTM A480/A480M
General requirements for stainless steel plate, sheet and strip include dimensional, tolerance, finish and ordering provisions used together with the applicable material specification.
Surface Roughness
Polishing grit or surface roughness can be specified where cleanability, hygienic service, sealing or process performance requires a controlled surface.
Surface Treatment
Pickling, Passivation & Surface Cleaning
Free-iron contamination, residual heat tint, scale and unsuitable surface preparation can cause staining or localized corrosion even when the specified stainless steel grade is correct. Pickling and passivation requirements can therefore be included where the application or fabrication route requires additional surface cleaning.
Pickling
Oxide & Heat-Tint Removal
Removes scale, heat tint and surface oxides generated during hot processing or welding.
Passivation
Free-Iron Removal
Chemical cleaning removes free iron and other surface contamination before the passive surface re-forms.

SUPPLY NETWORK
Our Mill & Supply Network
We work with established mills and specialty metal producers across stainless steel, titanium and nickel alloys to support a wider range of grades, forms and delivery requirements.
01
Pricing follows the engineering
These factors affect how TiAlloy prices any quote: provided here so you can be sure to come back a complete request the first time.
Grade and alloy content
Why it moves the number: Molybdenum, nickel and nitrogen content set the raw material cost floor.
State in your enquiry: Grade, or the service data if you want us to recommend one.
Form and dimension & Order quantity
Why it moves the number: Non-standard thickness or wall may require a dedicated production run. A production slot has a minimum economic tonnage per heat.
State in your enquiry: Stainless steel plate sizes or wall and diameter, plus tolerance class. Tonnage or piece count, and whether it repeats.
Certificate type & Test scope
Why it moves the number: EN 10204 3.2 adds an independent inspector and calendar time. Impact, intergranular corrosion and eddy current testing add process steps.
State in your enquiry: 3.1 or 3.2, and the nominated inspection body. Required tests and acceptance criteria.
02
Production lead time is quoted as a confirmed production slot with the quotation.
We are happy to make two formal promises to you because these are the areas where customers are most frequently let down.
Firstly, TiAlloy quotes a production slot, not a “hoped for date.” Secondly, if the production slot moves, we proactively inform you, no need to chase us! We specify the minimum order quantity by grade and form, not as a flat figure for everything and confirm this in writing with the quote.
03
Strict Delivery Standards
Delivery terms deserve the same rigorous approach, because specifying the Incoterm determines when duty, freight and brokerage are charged: it’s a contract term, not an accounting term.
For the importer of record, the entry documentation required and the process that governs payment of these duties and taxes is published by U.S. Customs and Border Protection. Tell us the Incoterms you use and we’ll quote within them.
04
Send this and the quote comes back
Grade or service parameters, dimensions and form, quantities, certificate and tests required, and shipping terms and final destination. That’s all you need to make a complete inquiry.
Any inquiry less than that gets you an estimate that is less granular than it looks – and that’s the trap behind most low price quotes.

PREN is a comparative alloy index calculated from chemical composition. It is useful for comparing pitting-resistance potential between stainless steel grades, but it should not be used alone to establish suitability for seawater, chloride or other corrosive service.

FAQ — Stainless Steel Sourcing Questions
Safety is achieved through verification of origins not with an assertion of nationality. Seek the company’s business license, an raw unedited plant video, and heat traceability certificate prior to purchasing, then confirm delivered material by matching the heat numbers on the tags and using an XRF or OES analyser to verify the alloy. Specify EN 10204 3.2, when its use justified, and an independent inspector sign it off for you.
What differentiates a mill from a reseller? Four key areas: 1) the certificate is issued by the actual melting plant, 2) grades beyond 304/316 are offered, 3) quote details grade, standard and test scope, 4) lead time is expressed as a production slot. We are a stainless steel distributor but where traceability is critical, the first factor stands alone.
Split the question by exposure, because a single answer does not encompass a hull fitting and a hand rail. For pristine immersion, the honest answer is super austenitic or super duplex – grades that sit above the PREN 32 cut-off point, which within our choice of grades is 904L, 2205 and 2507. For splash zone and near-coastal air, 316L works where it is rinsed by rain or rinsed on a maintenance cycle, but it will stain and slowly pit under the build-up of salts, and a crevice such as a bolted flange hastens the pit. The key inputs are chloride level at a point in the cycle, maximum metal temperature and is a crevice present. Send us those three and we will tell you what grade we would recommend, and we will do so clearly stating where 316L is being asked to perform a task it cannot.
Both 321 and 347 are stabilised by titantium and niobium respectively, to retard sensitisation at welds, and 310S has the highest combined chromium and nickel in our ranges, for corrosion resistance to oxidation. Stabilized types are the response most often used when a welded structure will repeatedly pass through the disintegration range.
Chloride level measured, temperature of peak metal temperature, is there a crevice present, what strength is needed, what method of fabrication will be used. Whether a grade is familiar should be last on that list, because that is the input that more often than not results in both over- and under- specification.
Correct bar. It is rolled via the bar route, and then either peeled, ground or drawn to the specification ordered, and the quotation states this.
Both are fixed per grade and form, because the lot for a duplex heat and a 304 coil run do not have the same minimum. We reaffirm the figure in writing at quotation along with the production slot, so request with your grade, form and dimensions and you will receive an answer specific to your needs, rather than a range.
