These elements are not intentionally added to improve the quality of steel, but are brought in by ore and smelting process, so they are called impurity elements.GB 40CrNi2Mo GB/T 3077 - BBN STEEL STORESGB 40CrNi2Mo GB/T 3077 chemical. Carbon, Silicon, Manganese, Phosphorus, Sulfur are the main basic elements in GB 40CrNi2Mo GB/T 3077. Carbon is the most important hardening element in steel. Silicon helps to strengthen the strength. Like manganese, silicon is used to maintain the strength of steel during steel production.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This gb t 3077 40b steel chemical element alloy steel gb t 3077 40b steel chemical element still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
