Surface quality inspection of high strength low alloy steel plate S690QL

high strength low alloy steel plate S690QL, Pressure vessel steel plate is mainly used to make pressure vessels. But according to its temperature, corrosion resistance and other characteristics, the material of the pressure vessel steel plate used for pressure vessels is also different. The most common oil tanks in our lives, liquefied gas tanks are all made of pressure vessel steel plates. According to the purpose, the pressure vessel steel plate can generally be divided into: pressure vessel steel plate, low temperature pressure vessel steel plate and boiler pressure vessel steel plate, etc..

Alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. Welding and forming of this steel plate high strength low alloy steel plate S690QL should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary. We can supply ASTM, JIS, DIN and GB various standards alloy steel grades.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the high strength low alloy steel plate S690QL steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the high strength low alloy steel plate S690QL weathering steel is purified and the content of inclusions is greatly reduced.

We have replenish steel materials stocks, now there are huge stocks of S355JR, A36, high strength low alloy steel plate S690QL A572 Gr 50, 16Mo3, A516 Gr 70, ABS grade A, AH32, AH36, EH36, SPA-H, SG295,SM700C etc steel materials. We can arrange delivery for those stock steel products within short time. Meanwhile, we also provide further processing for the high strength low alloy steel plate S690QL steel materials, such as cutting, drilling, bending, welding, etc. Please do not hesitate to contact us if you have any steel demands.
