Online Q355GNH steel order, 45Mn2 steel is a kind of alloy structural steel. 45Mn2 steel is made of high-quality carbon structural steel with proper addition of manganese. 45Mn2 steel belongs to the medium carbon quenched and tempered steel in alloy structural steel. The parts made with 45Mn2 steel can obtain high strength and good toughness after quenching and tempering at high temperature. That is to say, 45Mn2 steel has good comprehensive mechanical properties and is often used to manufacture shafts, connecting rods, fasteners which bear large loads.

Grades Online Q355GNH steel order, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.

The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The Online Q355GNH steel order, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.
