The implementation standard of 27SiMn seamless steel pipe is GB/T17396-2018, which is mainly used in seamless steel pipe for fluid, seamless steel pipe for boiler, high-pressure seamless steel pipe for boiler, high-pressure seamless steel pipe for fertilizer equipment and other fields.
27SiMn steel pipe has a carbon content of 0.24-0.32%, and a high silicon-manganese content of about 1.10-1.40%. It has good hardenability and wear resistance. At the same time, the toughness is not reduced much during heat treatment, ensuring the combination of high strength and wear resistance. Precision processing technology can ensure the smooth inner wall and precise size of the cylinder tube, thereby improving the sealing and service life of the cylinder.
