Temper embrittlement refers to a phenomenon where quenched steel becomes brittle after tempering within certain temperature ranges or after slowly cooling through these ranges. It can significantly affect the toughness and reliability of steel components. Classification of Temper Embrittlement Temper embrittlement

In the arc zone, temperatures can reach up to 4000°C. The steelmaking process inside an EAF generally includes three stages: Melting phase Oxidation phase Reduction
Read more →Background and Significance In recent years, the high-end cast and forged parts market has seen rapid growth, with increasing demand for premium-quality forgings. However, traditional melting and casting techniques often struggle to meet the stringent requirements of advanced forgings, such as bellows, 18-18 retaining rings, and H13
Read more →16MnCr5H is a German-grade steel known for its good hardenability and machinability. After heat treatment, it provides high hardness, strong wear resistance, and good impact toughness at low temperatures. This Mn-Cr alloy steel is widely used in automotive gears for models like Santana, Audi, and Jetta. However,
