ASME SA268 TP410 Seamless Stainless Steel Tube
The ASME SA268 TP410 seamless stainless steel tube is a widely used martensitic grade known for its moderate corrosion resistance, high strength, and hardness. Manufactured via a seamless process, it ensures structural integrity for pressurized applications. This grade is typically supplied in heat-treated conditions—such as annealed or quenched and tempered—to achieve desired mechanical properties, making it suitable for a range of industrial uses including steam systems, oil well tubing, heat exchangers, and mechanical components.
TP410 is a basic martensitic chromium stainless steel containing approximately 11.5% chromium, which provides corrosion resistance in mild environments. Unlike austenitic grades such as 304 or 316, it is magnetic and can be strengthened through heat treatment. Its final properties are largely determined by its heat treatment condition.

Key Characteristics |
Primary Application Guide |
| TP304 |
Excellent formability, good general corrosion resistance. |
The most common choice for general corrosive service (e.g., food, beverage, chemicals). |
| TP410 |
High strength & hardness; magnetic; moderate corrosion resistance. |
Selected for mechanical properties (wear, strength) in mild environments (e.g., steam, valves, cutlery). |
| TP316 |
Superior corrosion resistance, especially to chlorides and acids. |
The premium choice for aggressive environments (e.g., seawater, chemical processing, pulp & paper). |
