ASTM A479 316L Stainless Steel Angle for Pressure Vessel Construction
Shaanxi Shangyou Stainless Steel Co., Ltd. supplies ASTM A479/A479M Type 316L stainless steel angle for components used in boiler and pressure-vessel construction.
ASTM A479/A479M-25 specifically covers hot- and cold-finished stainless steel bars and hot-rolled or extruded shapes, including angles, tees and channels, for use in boilers and other pressure vessels. It should not be applied to an ordinary structural angle solely as a marketing label.
The buyer must identify the applicable design code, material specification, grade, product form, dimensions, heat-treatment condition and supplementary testing requirements. Compliance with ASTM A479 alone does not establish compliance with an entire pressure-vessel design code.
| Item | Supply Capability |

| Grade | 316L / UNS S31603 |
| Material Standard | ASTM A479/A479M |
| General Requirements | ASTM A484/A484M where applicable |
| Product | Angle or custom stainless section |
| Dimensions | Project specification or approved drawing |
| Traceability | Heat number throughout processing |
| Testing | Chemistry, mechanical properties, PMI |
| Documents | EN 10204 3.1 or agreed certificate |
| Inspection | Buyer or third-party hold points |
The RFQ should state whether the angle is a pressure-retaining component, an attachment, internal support or non-pressure structural item. The design engineer must confirm the permitted material and allowable stress values under the governing code.
Any cutting, welding, forming or heat treatment performed after certification must be controlled so that traceability and required properties are not compromised.
Available documentation can include MTC, heat-number transfer records, dimensional report, PMI report, NDT report, inspection and release note.
XRF PMI can distinguish major alloy families but cannot independently verify the low-carbon “L” designation. Carbon verification requires suitable analytical documentation or an appropriate laboratory method.
Its stated scope is boiler and pressure-vessel construction.
No. Vessel compliance depends on the governing design code and fabrication requirements.
XRF does not independently confirm the low carbon content required for an L grade.
Yes, when maintained through cutting and processing.
Yes, with agreed inspection points.
Yes, when specified and supported by the supply route.
Yes, subject to approved drawings and applicable standard requirements.
Yes, using a qualified procedure approved for the project.
It provides general requirements for stainless steel bars, shapes and related wrought products.
Code, standard, grade, size, condition, quantity, testing, documentation and inspection requirements.
