hardox 400 hot wear professional manufacturer in USA
Low alloy coils are steel coils made of steel with a low alloy content, usually less than 3.5%. Low alloy coil materials mainly include A572 Gr 50, S355JR, SS490, ST52-3, Q345B, etc.. These grades are also the most widely used and produced low-alloy high-strength steel grades in the world. The strength of low alloy coils is about 20% to 30% higher than that of ordinary carbon structural steel, HARDOX 400 hot wear. And the atmospheric corrosion resistance of low alloy coils is 20% to 38% higher than that of ordinary carbon structural steel.
Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of HARDOX 400 hot wear capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the HARDOX 400 hot wear overall strength, competitiveness and anti risk ability of the company.
Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous HARDOX 400 hot wear process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of HARDOX 400 hot wear etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in HARDOX 400 hot wear etc. steel is strictly controlled.
