L360N line pipe

Pipeline steel seamless steel pipe: L245N line pipe, L360N line pipe, L290N line pipe, L415 line pipe, L245, L360, L450 line pipe, L485 line pipe, X42, X52, X60, X56 line pipe, X65 line pipe Pipe, X70, X80 line pipe.

L360N line pipe is tempered at low temperature as tempered martensite. Its purpose is to reduce the internal stress and brittleness of the quenched steel while maintaining the high hardness and high wear resistance of the quenched steel, so as to avoid cracking or premature damage during use.

L360N line pipe is mainly used for various high-carbon cutting tools, measuring tools, GB/T9711.1 pipeline steel pipes, rolling bearings and carburized parts, etc. The hardness after tempering is generally HRC58-64. Tempered troostite is obtained by medium temperature tempering. Its purpose is to obtain high yield strength, elastic limit and high toughness. Therefore, L360N line pipe is mainly used for the treatment of various GB/T9711.1 pipeline steel pipes and hot work molds, and the hardness after tempering is generally HRC35-50.

Seamless pipes: 20#, 45#, Q345B, Q345C, Q345D cryogenic pipes, Q345E cryogenic pipes, 15CrMoG, 12Cr1MoVG, Cr5Mo alloy pipes, high pressure boiler pipes, special fertilizer pipes, oil cracking pipes and other seamless pipes.

L360N seamless steel pipe is tempered at high temperature and obtained as tempered sorbite. Customarily, the heat treatment combined with quenching and high temperature tempering is called quenching and tempering treatment, and its purpose is to obtain comprehensive mechanical properties with good strength, hardness, plasticity and toughness. Therefore, it is widely used in important structural parts of automobiles, GB/T9711.1 pipeline steel pipes, machine tools, etc., such as connecting rods, bolts, gears and shafts. The hardness after tempering is generally HB200-330.
