The main alloy elements in ASME SA335 alloy steel boiler tube P11 seamless pipe is chromium and molybdenum. The chromium helps to increase the tensile strength, yield strength, fatigue resistance, wear resistance as well as hardness property of P11 seamless pipe. The increase in those properties is ideal to prevent oxidation at high temperature applications. The molybdenum helps to strengthen the elastic limit of P11 seamless pipe and increases its temperature strength. ASME SA335 P11 is equivalent to ASTM A335 P11, as well as ASME ASTM (S)A213 T11 steel.

ASME SA335 alloy steel boiler tube P11 seamless pipe has good weldability and hardenability. Forming operations like bending and flanging, as well as fusion welding are well suited to P11 seamless pipe.
