X42MO steel pipe: The oil, gas or water pumped out of the ground is transported to oil and natural gas industrial enterprises through the line pipe. X42MO steel pipe includes seamless and welded pipes. The pipe ends have flat ends, threaded ends and socket ends; the connection methods are end welding, coupling connection, socket connection, etc.
The structure obtained by high temperature tempering of X42MO steel pipe is tempered sorbite. Traditionally, the heat treatment combining quenching and high temperature tempering is called quenching and tempering treatment. The purpose of the X42MO steel pipe is to obtain the comprehensive mechanical properties of strength, hardness, plasticity, and toughness.
Therefore, X42MO steel pipe is widely used in automobiles, GB/T9711.1 line pipes, machine tools and other important structural parts, such as connecting rods, bolts, gears and shafts. The X42MO steel pipe hardness after tempering is generally HB200-330.
