A quick-reference comparison — confirm your exact specification with us before ordering.
| Standard | Scope | Typically specified for |
|---|---|---|
| ASTM A249 | Welded austenitic stainless steel boiler, superheater, heat-exchanger, and condenser tubes. | Heat exchangers, condensers, heating elements |
| ASTM A269 | Welded austenitic stainless steel tubing for general service. | Instrumentation tubing, general corrosion-resistant service |
| ASTM A554 | Welded stainless steel mechanical tubing. | Structural, architectural, and decorative tube |
| ASTM A213 | Seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. | High-temperature heating elements (paired with A249 on our heating-element range) |
| ASME SA249 / SA213 | ASME Boiler and Pressure Vessel Code adoptions of the equivalent ASTM standards. | Specified where a project falls under ASME Code jurisdiction rather than ASTM alone |
Looking for grade composition and mechanical properties? See Grades & Materials.
Yes — every shipment is issued a traceable Mill Test Certificate (MTC) confirming grade, standard, and test results, as part of our standard quality process (raw material inspection, forming & welding, testing & inspection, then MTC issuance). This is standard practice for export orders and is generally required by buyers sourcing to a named ASTM/ASME standard.
