And sincerely to build NM500 grade material long-term cooperation with you.

How much a ton of alloy plates costs depends on the classification of alloy plates. Different alloy plates contain different elements, such as low-alloy steel (the total amount of alloy elements is less than 5%), medium alloy steel (the total amount of alloy elements is 5% - 10%), and high alloy steel (the total amount of alloy elements is more than 10%). If the alloy plates performance is different, the price will be different. The thickness of the alloy plates also affects the price. Besides, NM500 grade material, alloy plates price is related to the steel market. With the rise of steel raw materials, the purchase cost will be high and the overall price will be high.

The cold rolled sheet does not produce scale because it is rolled at room temperature. Therefore, the surface quality of cold plate is good and the dimension precision is high. In addition, the mechanical and technological properties of cold rolled coil are better than that of hot-rolled steel sheet. In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheet, NM500 grade material.

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

NM500 grade material, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of NM500 grade material and No. 20 steel is 7.85kg/cm3
