ASTM A312 Stainless Steel 253MA UNS S30815 Seamless Pipe Pickled and Annealed

ASTM A312 253MA / UNS S30815 / EN 1.4835 Stainless Steel Seamless Pipe

253MA, also known as UNS S30815, is a high-temperature austenitic stainless steel alloy that provides good oxidation resistance at elevated temperatures. It contains relatively high levels of both chromium and nickel, along with additions of nitrogen and manganese, to enhance its high-temperature capabilities. The alloy also exhibits good creep strength and structural stability at high temperatures, making it a valuable material in challenging operating conditions.

Key properties of 253MA / UNS S30815 include:

High oxidation resistance: It can withstand high temperatures and resist oxidation, making it suitable for use in heat treatment equipment, industrial furnaces, and other high-temperature applications.
Good creep strength: The alloy maintains its strength and structure even under prolonged exposure to high temperatures.
Excellent resistance to sulfidation and carburization: It can resist damage caused by sulfur and carbon compounds in harsh environments.
High weldability: 253MA stainless steel can be easily welded using common welding techniques.
