The company always adheres to the sa573gr.70 size principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great sa573gr.70 size cause. Customers are welcome to visit our company at any time. We are always ready to support you.

After quenching and tempering, the 40Cr alloy steel plate has good comprehensive mechanical properties, good low-temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28~60mm in water quenching and Ф15~40mm in oil quenching. In addition to quenching and tempering, 40cr sheet is also suitable for cyanidation and high-frequency quenching.

The wear-resistant layer of sa573gr.70 size wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy sa573gr.70 size carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the sa573gr.70 size, alloy wear-resistant steel plate is significantly improved.

sa573gr.70 size, Grade P295GH chemical composition under EN10028-2:2003 is displayed as follows. Chemical composition (C: 0.08 to 0.20; Cr: ≤0.30; Si: ≤0.40; Cu: ≤0.30;Mn: 0.90 to 1.50; Mo: ≤0.08;P: ≤0.025; Nb: ≤0.020;S: ≤0.015; Ni: ≤0.30;Al: ≤0.020; Ti: 0.03; N: ≤0.012; Vi: ≤0.02). The yield Strength MPa (min) of P295GH steel plate with thickness less than 16mm is 295MPa, and the tensile strength is 460-580MPa.

We have huge stocks for carbon steel plates, high strength low alloy steel materials, weather resistant steel sheets, wear resistant steel plates, boiler plates, pipeline steel, etc. Those stocks can be delivered within 10 days after deposit. We update sa573gr.70 size stock list regularly. But the stock changes quickly. It needs to check with warehouse specially when you have urgent needs. Welcome to contact us and book steel materials stocks.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
