High quality ASTM A335 High Temperature Steel Pipe

ASTM A335 high temperature steel pipe is a seamless ferritic alloy steel pipe for high temperature service with the following characteristics: Chemical compositionThe chemical composition of different grades is different. Taking the common P5, P9, P11, P22, P91, etc. as examples, the carbon content is generally between 0.05%-0.15%, the manganese content is 0.30%-0.60%, and the phosphorus and sulfur contents are low, respectively controlled below 0.025% and 0.025%. It also contains alloy elements such as chromium, molybdenum, and vanadium. The chromium content is between 1.00%-9.50%, and the molybdenum content is between 0.44%-1.13%. The addition of these alloy elements gives it excellent high temperature performance and corrosion resistance.Mechanical propertiesIt has high tensile strength and yield strength. Generally, the minimum tensile strength can reach more than 415MPa, and the minimum yield strength is more than 205MPa. At the same time, it has a certain elongation, can maint…
