AISI 8630
Low Alloy
AISI 8630 is a low-alloy steel known for its strength, toughness, and good hardenability. It contains approximately 0.28-0.34% carbon, along with 0.70-0.90% manganese, 0.40-0.60% chromium, and 0.80-1.10% nickel. These elements enhance its mechanical properties, making it suitable for applications requiring high strength and resistance to wear, such as gears, shafts, and heavy machinery components. AISI 8630 can be heat-treated to achieve desired hardness levels, and it offers good weldability. Its balance of toughness and strength makes it a popular choice in the automotive, aerospace, and industrial sectors.
