What is ASTM a335?
ASME SA335 / ASTM A335 , Chrome-Moly pipe is a seamless ferritic Alloy-Steel Pipe produced in nominal or minimum wall thickness for high temperature service. Pipe ordered to this specification shall be suitable for bending, flanging, similar forming operations and for fusion welding.
What is p22 material?
A335/SA335 Grade P22 Alloy Steel Seamless Pipes are Carbon steel pipes with addition of chromium, molybdenum, and sometimes vanadium. Chromium, or chrome, improves high-temperature strength, increases oxidation resistance and raises the tensile, yield and hardness at room temperatures.
