A240A240M

A240A240M is a designation that commonly refers to a standard for stainless steel sheet and plate. This standard is published by ASTM International, a global leader in developing and publishing voluntary consensus technical standards for a wide range of materials, products, systems, and services. The "A240" part of the designation typically indicates the general scope of the standard, which is for chromium and chromium-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. The "A240M" is the metric equivalent of the standard.

This standard specifies the chemical composition, mechanical properties, and permissible manufacturing tolerances for various grades of stainless steel. These grades are often used in industries where corrosion resistance and strength are critical, such as the chemical processing industry, food and beverage production, and in the construction of pressure vessels. The standard ensures that the materials meet specific requirements for quality and performance, making it a crucial document for engineers, manufacturers, and specifiers. Different types of stainless steel fall under this standard, each offering a unique balance of properties for specific applications.
