Do you know the EN 10025 S890Q high strength steel hardness?

SA299 Gr.B steel is C-Mn-Si steel plate often used to make various welding parts whose working temperature does not exceed 400 degrees Celsius, such as the head and shell of boiler steam drum, pressure vessel. Due to its working environment, SA299 Gr.B plate is required to have a higher medium temperature, outstanding shaping and heat treatment process functions, and outstanding welding functions.

In recent years, in line with the development trend of iron and EN 10025 S890Q high strength steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which EN 10025 S890Q high strength steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

The EN 10025 S890Q high strength steel stainless steel 2250 mm wide coil mill has advantages such as adapting to difficult-to-deform steel grades. The Liuzhou Iron and Steel Hot Rolling Leveler project designed and supplied by MCC South is equipped with the latest straightening and leveling process (LTP technology) developed by MCC South. The EN 10025 S890Q high strength steel performance stability, cost and various consumption indicators have reached the international advanced level.

The addition of Ca element in steel such as EN 10025 S890Q high strength steel can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
