Ordinary low alloy steel is a common alloy steel containing a small amount of alloying elements (the total amount does not exceed 3% in most cases). This kind of steel has relatively high strength, relatively good comprehensive properties, corrosion resistance, wear resistance, low-temperature resistance, good cutting performance, welding performance, etc. Under the condition of saving a large amount of scarce alloy elements (such as nickel and chromium), it is usually 1t of ordinary low alloy steel can be used as much as 1.2-1.3t of carbon steel, and its service life and use range far exceed that of carbon steel. Ordinary low alloy steel can be smelted in an open hearth or converter using general smelting methods, and the cost is close to that of carbon steel.
