Thin steel plate is a kind of steel plate material that is thinner in thickness. Generally, steel plate with thickness less than or equal to 4mm is called thin steel plate. As we all know, the steel products we usually see are also divided into different thicknesses. The strength, performance and scope of application of different thickness steel plates, S690QL1 steel grades are also different. Today, we will talk about some related knowledge of thin steel plates, and take you to understand the characteristics and uses of thin steel plates.

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel S690QL1 steel grades is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This S690QL1 steel grades production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate S690QL1 steel grades size.

As for the mechanical properties of S690QL1 steel grades, ASTM A572 Gr.50, 345 Mpa is the yield point levels most closely approximating a geometric progression pattern between 36 ksi min yield point steels covered by Specification A36/A36M and 100ksi min yield point steels covered by Specification A514/A514M.
