Alloy Steel AISI 8630 Bars are robust steel bars crafted for tough industrial and engineering tasks. Made from a blend of nickel, chromium, and molybdenum, these bars are known for their impressive toughness, fatigue resistance, and hardenability. Thanks to advanced forging and rolling techniques, they boast uniform dimensions, a superior surface finish, and reliable mechanical properties. They comply with international standards, making them perfect for critical roles in industries like automotive, aerospace, heavy machinery, and power generation, where reliability, durability, and performance are non-negotiable.
Alloy Steel AISI 8630 Bar is a low-alloy steel with a compositional balance of Carbon (0.28-0.33%), Manganese (0.40-0.60%), Chromium (0.40-0.60%), Nickel (0.40-0.70%), Molybdenum (0.15-0.25%), and Iron as the base material. It provides superior mechanical properties, such as tensile strength of 850-1100 MPa, yield strength of 650-850 MPa, and high toughness. Its hardness is between 217-285 HBW, giving it wear resistance. It is perfect for stress applications in aerospace, oil & gas, and automotive industries where it delivers greater machinability, weldability, and resistance to impact.
