AISI 4140 alloy steel has a high carbon content (usually between 0.40% and 0.55%) and contains appropriate amounts of chromium and molybdenum elements, which give it extremely high strength and toughness. This makes AISI 4140 alloy steel exhibit excellent fracture resistance when subjected to impact... read more
1. High strength and wear resistance By adding appropriate amounts of alloy elements, such as chromium (Cr), molybdenum (Mo), etc., alloy steel can significantly improve the strength and hardness of the steel while maintaining good wear resistance. This is crucial for components such as screws and b... read more
