4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. q355gnh steel beam, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the q355gnh steel beam quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After q355gnh steel beam quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

In 2015 , We get the tender from Myanmar Government, the total quantity is 1200 ton ABS-AH36 steel plate, we supply the steel plate with painting ( which standard is according to ISO SA2.5) with gray Color 20 Micron.
