ASTM A240 is a standard for chromium and nickel stainless steel plates and strips used primarily in pressure vessels and general applications. 316 is an important material code under this standard, referring to a stainless steel variety with a specific chemical composition and mechanical properties.
ASTM A240 316 stainless steel Features:
316 stainless steel contains molybdenum, which makes it better than other stainless steel varieties, such as 304 stainless steel, pitting resistance and resistance to chloride environmental corrosion. It also shows good machinability, strength and toughness, and can maintain excellent performance even at low temperatures. 316 stainless steel also has good oxidation resistance and high temperature stability.
The main chemical components of 316 stainless steel include iron, chromium, nickel, molybdenum and other trace elements such as manganese, silicon, carbon, phosphorus and sulfur. Among them, the content of chromium is about 16% to 18%, the content of nickel is 10% to 14%, and the content of molybdenum is about 2% to 3%. The content of these elements is precisely controlled to ensure excellent corrosion resistance and mechanical properties of the material.
The delivery status of 316 stainless steel is usually customized according to the specific needs of the customer 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, 316 stainless steel is widely used in many fields, including but not limited to chemical production, oil and gas, medical devices, Marine engineering, shipbuilding and construction. It is often used in the manufacture of acid and alkali resistant, salt spray resistant, corrosion resistant equipment and pipelines, as well as high temperature and high pressure environment applications, such as chemical reactors and oil pipelines.
