ASTM A268 TP410 Stainless Steel Seamless Pipe For Heat Exchanger

ASTM A268 TP410 stainless steel pipe is a ferritic stainless steel tube suitable for heat exchangers, conforming to the ASTM A268/A268M standard specification, which covers the technical requirements for general-purpose seamless and welded ferritic and martensitic stainless steel tubes.

ASTM A268 TP410 stainless steel pipes we supply are designed for general applications, particularly in heat exchangers. They offer a combination of good mechanical strength, high hardness, and moderate corrosion and heat resistance. Key features include the ability to be hardened through heat treatment to achieve enhanced strength, as well as a cost advantage due to their nickel-free composition. Widely used in petrochemical equipment, automotive components (such as exhaust systems and heat exchangers), and other fields, these pipes effectively meet the heat exchanger requirements for material strength, thermal resistance, and corrosion resistance.
