The heat treatment hardness of DC53 mold steel is higher than that of SKD11, RE 40 marine grade ship steel plate, the high temperature is 520-530 ℃, and the high hardness can reach 62-63HRC after tempering. In terms of strength and wear resistance, mold steel DC53 exceeds SKD11 mold steel. The toughness is twice that of SKD11 die steel. The toughness of DC53 is more prominent in cold work die steel. Tools made with DC53 rarely crack and crack, greatly increasing the service life.
Compared with carbon steel, alloy steel plate is a steel plate with other alloy elements added to the material, and the material performance is more excellent. Compared with other steel plates, alloy steel plates have outstanding performance. First, RE 40 marine grade ship steel plate, alloy steel plate has higher strength, stronger bearing capacity, less breakage when bearing large objects, and longer service life. Second, alloy steel plate has good corrosion and wear resistance. In the open air environment, the steel selected for road and bridge paving must have high corrosion resistance and wear resistance, otherwise it will be damaged after a period of use and it will easily lead to accidents.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the RE 40 marine grade ship steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between RE 40 marine grade ship steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
We have a professional production team and high-quality production equipment, and we also have a great RE 40 marine grade ship steel plate advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the RE 40 marine grade ship steel plate production of high-quality steel plates, steel pipes and other products that meet customer requirements.
From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
