There are many kinds of heat treatment processes for wear-resistant composite plate, S690QL steel hardness, and they are applicable to different ranges. For example, direct quenching and low-temperature tempering can not refine the grain size of steel, the quenching deformation of workpiece is large, and the surface residual austenite volume of carburized parts of hardfacing wear-resistant composite plate is more, and the surface hardness is lower. It is suitable for gas carburizing and liquid carburizing.

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. After Get Customer Contract, Steel Plate Are Produced within 25 days .Then, Goods transported to Tianjin Port And Shipping On Time To Statisfy With Project Expected After Finished Producing. The Steel Quality S690QL steel hardness we offered receive good Praise from our Customers .

ASTM A537 class 1 boiler plate is pressure vessel steel. S690QL steel hardness, A537 class 1 boiler plate chemical elements include C, Si, Mn, P, S, Mo, Ni, etc. Among them, the carbon content is 0.24 max., Si content is 0.13-0.55%, Mn content is 0.92-1.72%, the max. contents for both P and S are 0.035%, the Mo content is 0.09% max, and the Ni content is 0.38% max. A537 class 1 boiler plate properties: A537 class 1 boiler plate tensile strength is 450-585 MPa, min. yield strength is 310 MPa, and min. elongation in 2 in.(50mm) is 18%.
