Hydraulic prop tube, the implementation of standard GB/T17396-1998. Mainly used to make coal mine hydraulic prop and cylinders, columns, and other hydraulic cylinders and columns.
The hydraulic prop tube represents materials of 20, 45, 27SiMn and the like.
The hydraulic prop tube is based on high-quality carbon structural steel, and one or more alloying elements are appropriately added to improve the strength, toughness and hardenability of the steel. After being made of such steel, it is usually subjected to heat treatment such as quenching and tempering, chemical heat treatment and surface hardening. Compared with high-quality carbon structural steel, it has good comprehensive mechanical properties and is rolled into round, square and flat steels, which are used as important structural parts in machinery or machinery.
The hydraulic struts are less resistant to rust than stainless steel. However, wear resistance and machinability are much better than stainless steel.
