United States and Canadian buyers specify to ASTM and ASME more than to anything else. We quote against the ASTM designation, the UNS number and the product form, and we state in the quotation which standard governs the material and which one governs the inspection.
The grades we are asked for most often, and the service environment behind each of them.
Sour service, high-pressure pipe and high-temperature process service. 625 and C-276 for chloride and sour environments, 800H and 800HT for creep-limited heater and exchanger duty.
Hastelloy C-276, C-22 and B-2 for the acid services where 316L and 825 give way. We work from your corrosion study, not from a grade list.
690, 625 and 718 for turbine and reactor service, with the elevated-temperature mechanical properties reported against the section size.
Monel 400 and 400 for seawater service, and the nickel alloys used in fasteners and forgings supplied to A 484 dimensional tolerance.
825 and 904L where the process carries chlorides or sulphuric acid at elevated temperature.
We quote to the standard on your purchase order. Where two standards apply — one for the material, one for the inspection document — the quotation states which governs which.
| Standard | What it covers |
|---|---|
| A 276 / A 276M | Stainless steel bar and shapes |
| A 240 / A 240M | Chromium and chromium-nickel stainless plate, sheet and strip |
| A 480 / A 480M | General requirements for stainless steel plate, sheet and strip |
| A 484 / A 484M | General requirements for stainless steel bar, billets and forgings |
| A 693 | Precipitation-hardening stainless steel plate, sheet and strip |
| A 705 | Pressure vessel steel forgings and weldments |
| B 160 / B 161 | Nickel bar, and nickel seamless pipe and tube |
| B 163 | Nickel-chromium-iron seamless pipe and tube |
| B 165 | Nickel-copper seamless pipe and tube |
| B 167 | Nickel-chromium-iron seamless pipe and tube |
| B 407 | Nickel-iron-chromium seamless pipe and tube |
| B 444 | Nickel-chromium-iron-alloy seamless pipe and tube |
| B 622 | Nickel-chromium-molybdenum-copper seamless pipe and tube |
| B 829 | Nickel and nickel-alloy seamless pipe and tube |
| SB 165, SB 167, SB 407, SB 444, SB 622 | The ASME counterparts of the B specifications above, for code work |
| A 751 / A 751M | Test methods for steel products, including chemical analysis |
| E 8 / E 8M | Tensile test method |
The paperwork is quoted before the order is placed, not assembled afterwards. A 3.2 certificate in particular has to be arranged before manufacturing, because it needs a second party present.
Three checks catch most problems, and all three are yours to make:
State the term and the destination port in your enquiry and we will quote against it. We do not add a surcharge later.
The usual starting point. You take the container at the terminal and arrange the onward move.
We quote sea freight and minimum insurance to your nominated port. State the port and the named vessel window you need.
We deliver to your door on the terms you nominate. Duties and import clearance in your country stay yours.
Available for small, urgent or sample quantities. Weight and dimensional limits are confirmed with the quotation.
The grades our customers in North America order most often, taken from the standards listed above. Every one links to its full composition, mechanical data and supply forms.
We supply into both. Most North American business goes through a distributor or a stockist who holds the material locally, but we also ship direct against a purchase order where the buyer prefers it.
Yes. Where the material goes into code work, we quote the ASME designation alongside the ASTM one and confirm the specification on the order.
Both are available. The certificate type, the validating party and the tests to be witnessed are stated in the quotation before you order, not decided afterwards.
Grade, form, dimensions, quantity, application and required delivery date. Add the standard and the certificate type you need, and any drawing or specification you are working to. That is enough for us to quote and for you to compare.
