10 mm thickness hot rolled hardox 450 plate used for properties

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of Hardox 450 plate used for, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

By Region: data shows that in the first quarter of Asia, crude steel Hardox 450 plate used for production was 315.2 million tons, down 0.3% year on year. Crude steel production in the EU region in the first quarter was 38.3 million tons, down 10.0% year on year. The output of crude steel in North America in the first quarter was 29.5 million tons, down 4.0% year on year.

The steel such as Hardox 450 plate used for delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

How to improve the wear resistance of wear-resistant plate, Hardox 450 plate used for?1. Grain refinement to promote the increase of dislocation density under stress state.2. Reduce the Mn content to reduce the Austenite Stability of wear-resistant plate and achieve the ability of accelerated work hardening.3. Cr, Mn, V, Ti and other elements are added to improve the wear resistance of the wear-resistant plate, and the carbide is dispersed in austenite to enhance the wear resistance.
