Cutting treatment and heat treatment of GB/T 4171 Q295GNH, Q355GNH steel coil

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium GB/T 4171 Q295GNH, Q355GNH steel coil carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some GB/T 4171 Q295GNH, Q355GNH steel coil alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

GB/T 4171 Q295GNH, Q355GNH steel coil, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of GB/T 4171 Q295GNH, Q355GNH steel coil, Chinese grade 45 steel depends on its various properties. GB/T 4171 Q295GNH, Q355GNH steel coil, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.
