Seamless stainless steel pipe

A/SA 312, Grades 304/L and 316/L

Stainless steel is one of the most popular and versatile materials. Seamless stainless steel pipe is used in applications where high temperature strength and superior corrosion resistance are critical. Further, stainless steel is easy to clean and doesn’t tarnish.

Stainless steel is an iron alloy that contains a minimum of 10.5% chromium. Alloying elements such as nickel, molybdenum, titanium, carbon, nitrogen, and copper can boost the strength, formability, and other properties of stainless steel. Different alloys offer different levels of corrosion resistance. 

Stainless steel alloys offer greater cryogenic toughness, a higher work hardening rate, increased strength and hardness, greater ductility, and a more attractive appearance compared to carbon steel.

Benefits of stainless steel pipe

Stainless steel pipe is resistant to rust and other corrosive attack. It is heat-resistant for high-performance and high-temperature use.
