1Cr18Ni9Ti stainless steel pipe

1Cr18Ni9Ti stainless steel pipe is a hollow long steel material, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, coal gas, steam, etc. In addition, when bending and torsional strength are the same, the weight is lighter, so It is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, gun barrels, artillery shells, etc.

China's 1Cr18Ni9Ti is equivalent to American AISI321, 0Cr18Ni9 is equivalent to AISI304, 1Cr18Ni9 is equivalent to 302, 0Cr17Ni12Mo2 is equivalent to AISI316 1Cr18Ni9Ti=China Taiwan 321=International Standard X7CrNiTi18-10=Russia 12X18H10T=Japan SUS321=Germany 321 If For high temperatures of 700°C, 1Cr18Ni9Ti should be competent because it is both an austenitic stainless steel and a widely used austenitic heat-strength steel. However, it is best not to exceed 750°C. Its heat treatment is solid solution treatment. That is, it is heated to above 1000℃, kept for a certain period of time, then quenched with water, and then aged at 60~100℃ higher than the use temperature.
