ASTM A240 is a standard developed by the American Society for Materials and Testing that covers the specification of stainless steel sheets, strips, and sheets. 316L is an important material code under this standard, referring to low-carbon 316 stainless steel, with excellent corrosion resistance and mechanical properties.
ASTM A240 316L Stainless Steel Features:
316L stainless steel contains a low carbon content, which helps to reduce carbide precipitation during welding, thus improving the ability to resist intergranular corrosion. Compared with other stainless steels, 316L has better resistance to chloride corrosion and is especially suitable for Marine environments and chemical processing. It also shows good strength, plasticity and toughness, and is easy to process and weld.
The main chemical composition of 316L stainless steel includes iron, chromium, nickel, molybdenum and other elements. Among them, the content of chromium is 16% to 18%, the content of nickel is 10% to 14%, and the content of molybdenum is 2% to 3%. The precise ratio of these elements gives 316L stainless steel excellent corrosion resistance and mechanical properties.
The delivery status of 316L stainless steel is usually customized according to the customer's needs and can be hot rolled, cold rolled, annealed or other specific treatment status. Prior to delivery, the material is subjected to a rigorous quality inspection to ensure that it meets the requirements of ASTM A240.
Due to its excellent corrosion resistance and mechanical properties, 316L stainless steel is widely used in many fields. In the chemical and petroleum industries, it is often used to make corrosion-resistant equipment and pipes. In the Marine environment, such as offshore platforms, ships and Marine equipment, the excellent corrosion resistance of 316L stainless steel has been widely used. In addition, it is also used in food processing, medical devices, construction and decoration.
