Features of Stainless Steel as Valve Material:
Stainless steel is divided into three main categories depending on its chemical composition. They are martensitic stainless steel containing 13% chromium, ferritic stainless steel containing 18% chromium, and austenitic stainless steel containing 18% chromium and 8% nickel. Among them, austenitic stainless steel is widely used for both valve shells and trims, which require high pressure resistant characteristic. Martensitic stainless steel is used mainly for trims of carbon steel valves. The features and characteristics of these stainless steels are compared below:
Features of Stainless Steel by Types:
| Types | Martensitic | Ferritic | Austenitic |
| Typical Material | AISI 410 | AISI 430 | ASTM CF8M/F316 |
| Magnetization | Yes | No | |
| Hardening by heat treatment | Yes | No | |
| Hardening by machining | Same as soft steel | Less | |
| Corrosion and acid resistance | Good | Excellent | |
| Impact resistance and elongation | Good | Excellent | |
| Weldability | Poor | Fair | Good |
| Lowest service temperature | -29°C | -10°C | -269°C |
