An important feature of T91 boiler steel pipe is that it has strong ability to form martensite by air quenching and can be quenched into martensite by air cooling of 100 mm thick section. In general, lath martensite structure can be obtained by air cooling of T91 boiler steel pipe, which has higher strength and toughness due to fine lath martensite.
After high temperature tempering Katalor T91 boiler steel pipe obtained uniform high density dislocation and uniformly precipitated dispersed carbide particles. The T91 boiler steel pipe uniform distribution and high temperature stability of fine carbide particles are the key factors for the T91 boiler steel pipe high temperature rupture strength and plasticity.
The test results show that the high temperature tensile properties and rupture strength of the T91 boiler steel pipe produced by Katalor meet the requirements of ASME and GB5310 standards, and have satisfactory durability plasticity. The T91 boiler steel pipe holding this level can be used in the manufacture of power station boiler.
The analysis of electron microscope and transmission electron microscope proves that the T91 boiler steel pipe of Katalor has excellent quality and technological properties. S if you have any need in T91 boiler steel pipe, please contact us freely. We can give you the best price for you.
