The strength of S690QL steel suppliers, 20 # steel plate is slightly higher than that of 15# steel, rarely quenched, and has no temper brittleness. Cold deformation plasticity is high, generally for bending, calendering, flange and hammer arch processing. Arc welding and contact welding have good welding performance and small thickness during gas welding. Cracks are likely to occur on parts with strict shape requirements or complex shapes.

After quenching and tempering, 40Cr alloy steel plate and S690QL steel suppliers sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel S690QL steel suppliers is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

The steel plate cutting and processing instructions are as follows: steel plate cutting and steel plate cutting processing, as well as S690QL steel suppliers steel plate zero cutting processing. There are semi-automatic flame cutting, fully automatic CNC cutting, laser cutting and water cutting. The thickness range of steel plate that can be cut is 20650mm. In terms of S690QL steel suppliers steel plate cutting types, there are Q235B common plate, Q345B low alloy plate and 45 carbon bonded plate.
