ASTM A268 TP410 Seamless Tube Bright Annealed Heat Exchanger Tube
Leave a message
ASTM A268 is a standard specification developed by ASTM International, titled "Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service." It covers seamless and welded tubes primarily intended for general applications in moderate to high temperature and corrosive environments.
ASTM A268 TP410 is a martensitic stainless steel seamless tube specifically designed for general applications requiring high hardness, mechanical strength, and wear resistance, rather than extreme corrosion resistance.
TP410 stainless steel tubing demonstrates excellent heat treatment properties, as it can achieve a wide range of mechanical properties-from high toughness to high hardness-through quenching (oil or air cooling) and tempering. On the other hand, its weldability is relatively poor, since improper welding or post-weld heat treatment may lead to the formation of a hard and brittle martensitic structure, thereby increasing the risk of cracking in the welded area. Preheating before welding and post-weld treatment are usually necessary, especially for thick-walled TP410 seamless tubes.

ASTM A268 TP410 Stainless Steel Heat Exchanger Tube Application areas
Automotive industry: In the automotive industry, ASTM A268 TP410 stainless steel round tubes can be used as fuel pipes, oil pipes, hydraulic pipes, and exhaust system components. At the same time, attention should be paid to the corrosion of pipes by high-temperature oxidation and condensation.
Petrochemicals and Energy: ASTM A268 TP410 stainless steel cold rolled tubes can be used for instrument pipes, heat tracing pipes, boiler feedwater pipes, and heat exchanger pipes in mild corrosive environments, but attention should also be paid to water quality and chloride content.
Mechanical manufacturing: In terms of mechanical manufacturing, ASTM A268 TP410 stainless steel seamless tubes can be used as hydraulic and pneumatic system pipelines, bearing sleeves, wear-resistant components (after heat treatment), and shafts.
