27siMn alloy seamless steel pipe

27SiMn alloy seamless steel pipe, the implementation of standard GB/T17396-1998.

27SiMn alloy seamless steel pipe is based on high-quality carbon structural steel, and one or several alloying elements are appropriately added to improve the strength, toughness and hardenability of the steel. After this type of steel is made, it usually needs to undergo heat treatment such as quenching and tempering, chemical heat treatment, and surface quenching.

Compared with high-quality carbon structural steel, 27SiMn alloy seamless steel pipe has good comprehensive mechanical properties. It is mostly rolled into round, square, and flat steel, which is used as an important structural part in machinery or machinery. The hardness reaches HB285, which should be It is a quenched and tempered supply material.

Steel pipes, seamless pipes and precision pipes are hot-rolled (extruded, expanded) and cold-drawn (rolled) seamless pipes made of steel used for conveying water, gas, air oil and heating steam and other general lower pressure fluids and other purposes. Steel Pipe.

27SiMn alloy seamless steel pipe is mainly used to make coal mine hydraulic supports, cylinders, columns, and other hydraulic cylinders and columns. Its representative materials are 20, 45, 27SiMn, etc.
