Technical specifications and scope of the ASTM A479 standard
The ASTM A479 (ASME SA 479) specification is a key industry standard governing the production of stainless steel bars and shapes. This standard covers products obtained through hot and cold working methods, including round, square, and hexagonal sections, as well as hot-rolled and extruded profiles (angles, tees, channels). The primary purpose of products conforming to this standard is the manufacturing of components for boiler equipment and pressure vessels.
Products supplied by EV Group China fully comply with the requirements of ASTM A479, which ensures the reliability of components in high-temperature and aggressive environments.
Regulatory framework and classification
Standards for nickel-chromium, austenitic, and corrosion-resistant steels, as well as heat-resistant alloys, are under the jurisdiction of ASTM Subcommittee B02.07 (section 02.04 of the ASTM catalog). EV Group China ensures strict compliance control for all supplied metal products against these international requirements.
The document permits the use of both the inch-pound system and the SI metric system. It is important to note that values in these systems are not direct mathematical equivalents; therefore, the choice of measurement units when placing an order with EV Group China must be unambiguous. The use of a designation without the “M” suffix implies supply in the inch-pound system.
