Samuel Steels stands out as a top manufacturer and supplier of Alloy Steel AISI 8630 Bars in Abuja, Nigeria. They offer high-quality alloy steel bars that are celebrated for their remarkable strength, toughness, and versatility. AISI 8630 is a low-alloy steel enriched with nickel, chromium, and molybdenum, providing excellent hardenability and resistance to fatigue. These bars find their place in critical industrial components that demand superior mechanical performance under pressure. With advanced manufacturing processes, Samuel Steels guarantees precise dimensions, consistent composition, and a top-notch surface finish. Their AISI 8630 Bars are perfect for use in automotive, oil and gas, heavy machinery, and power transmission systems.
Alloy Steel AISI 8630 Bars generally consist of carbon (0.28–0.33%), manganese (0.40–0.70%), silicon (0.20–0.35%), chromium (0.40–0.60%), nickel (0.40–0.70%), and molybdenum (0.15–0.25%), with iron making up the rest. These bars showcase a tensile strength ranging from 830 to 930 MPa and a yield strength of about 415 MPa, along with an elongation of roughly 20%. They are known for their high toughness, fatigue resistance, and good impact strength, even in low temperatures. The balanced composition of the alloy ensures excellent hardenability, machinability, and weldability, making it ideal for heat treatment processes like carburizing and quenching.
