ASTM A403 Stainless Steel WP316 / 316L Pipe Nipple

Stainless steel is known for its excellent properties, high strength, corrosion resistance, and durability. With its remarkable features, stainless steel is used in various industries, including construction, automotive, and aerospace. One of the most popular types of stainless steel is the ASTM A403 Stainless Steel 316. ASTM A403 Stainless Steel 316 Pipe Nipples are made from grade 316, a type of austenitic steel containing a significant amount of molybdenum. Molybdenum is an additive that provides enhanced corrosion resistance and overall strength. The American Society sets ASTM A403 standards for Testing and Materials (ASTM), and they define the properties and dimensions of pipe fittings.
