What is ASTM A335 pipe?
We also call ASTM A335 pipe as ASME S/A335 Chrome-Moly pipe, it is a type of seamless pipe could be used in high temperature environments of 540 – 750 °C.
The A335 pipes are generally called chrome moly pipe as they have a high level of Chromium and Molybdenum presence in it. While Molybdenum increases the overall strength, resistance, elasticity, hardenability and overall quality, moly ensures that the material is more resistant to softening, restrains the growth of grains and lessens the chances of embrittlement. It is the single additive that is responsible for the increase in high temperature resistance and it also improves the corrosion resistance to steel.
