What is thickness range of hardox 450 steel equivalent material in China

Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the thickness range of Hardox 450 steel hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the thickness range of Hardox 450 steel steel industry.

The difference between alloy steel plate and carbon steel has the following points. First, the hardenability of carbon steel is low, and the maximum diameter of water quenching of carbon steel is only 10 mm to 20 mm; second, the strength of carbon steel is only 235 MPa, while that of alloy steel is more than 360 MPa. Third, carbon steel has poor tempering stability. In order to ensure high strength, low tempering is used for carbon steel during quenching and tempering treatment, so the toughness of the carbon steel is insufficient. Fourth, the corrosion resistance, low heat resistance, and wear resistance of carbon steel cannot be compared with alloy steel, thickness range of Hardox 450 steel.

The alloy layer of clad wear-resistant plate is mainly made of chromium carbide, and it is also equipped with molybdenum, niobium, titanium, boron and other components. The formation of multi-element carbides also has strong stability at high temperatures and can still be maintained below 500 °. High hardness and good oxidation resistance. The new clad wear-resistant plate thickness range of Hardox 450 steelhas multiple performances of wear resistance, corrosion resistance, temperature resistance and impact resistance.

When pouring the steel with high Mn content, some manganese oxide should be added in the initial slag in advance to prevent the occurrence of the above events. In order to prevent the longitudinal crack of wear-resistant steel plate, thickness range of Hardox 450 steel, some measures are often taken to reduce the content of P, S and Se in NM360 wear-resistant steel plate. Strictly control the liquid level fluctuation of the crystallizer; reasonably control the negative sliding time; try to increase the temperature difference of the water in the crystallizer as much as possible.

S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. thickness range of Hardox 450 steel, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265. Tensile strength: 450-680MPa.
