This force is typically applied using hammers or presses. The forging process refines the grain structure of metals and enhances their physical properties.
Read more →Importance of Heat Treatment in Large Forged Steel Parts Large forged steel components play a critical role in shipbuilding, railways, electric power, petrochemicals, metallurgy, and aerospace. These parts support national economic development and ensure the safety and reliability of high-end equipment. Their quality directly affects the performance
Read more →What Is Temper Embrittlement in Steel? 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
Read more →Electric Arc Furnace (EAF) Principle of EAF The Electric Arc Furnace (EAF) primarily relies on the intense heat generated by electric arcs. 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,
