Technical aspects and scope of the ASTM A240 specification
The ASTM A240 specification defines strict requirements for the production of flat-rolled products—sheets, plates, and strips—made from corrosion-resistant chromium, chromium-nickel, and chromium-manganese-nickel steels. These products are intended for the manufacturing of critical pressure-bearing equipment, as well as for a wide range of general industrial applications: from architectural structures to high-tech engineering systems.

Note: The ASTM A240 specification utilizes both inch-pound and SI unit systems. These systems are independent and are not interchangeable. Unless the “M” designation is specified in the order, the product will be supplied in accordance with the inch-pound system requirements.
Technical characteristics and operational advantages of ASTM A240 rolled products
Flat-rolled products regulated by the ASTM A240 standard possess high resistance to aggressive environments, thermal stress, and mechanical wear. The combination of alloying elements ensures the stability of the metal structure in critical components.
EV Group China offers the supply of stainless steel flat products used in the following areas:
- Manufacturing of pressure vessels and tanks.
- Creation of corrosion-resistant pipeline valve components.
- Shipbuilding and marine engineering.
- HVAC systems for challenging operating conditions.
- Construction of architectural structures and decorative elements.
To order high-quality flat-rolled products per the ASTM A240 specification, please use the contact form or reach out to the EV Group China sales department.
