ASTM A335 P11 Alloy Steel For Fire Furnace， Convection， Radiant Equipment
ASTM A335 P11 is a low alloy steel that is used in many industrial applications. It has a high chromium content， providing it with excellent corrosion resistance and heat resistance. It also has good mechanical properties， making it an ideal choice for many applications.
The ASTM A335 P11 Pipe consists of low alloy steel which has high temperature properties. This material exhibits good performance in high temperature conditions， like heat exchangers， pressure vessels， etc. The ASTM A335 P11 Pipe can be also used in industries such as power plants， oil and gas plants， etc. The addition of chromium makes it have high temperature strength， oxidation resistance， tensile strength， yield strength， and hardness.
