Nippon Alloys Inc is a leading 4320 Alloy Steel Round Bar Manufacturer in india. 4320 alloy steel is a high-strength, low-alloy steel known for its excellent toughness, wear resistance, and hardenability. It contains nickel, chromium, and molybdenum, which enhance its mechanical properties, making it suitable for applications requiring high durability and impact resistance. The round bar form of 4320 steel is commonly used in the manufacturing of gears, shafts, and heavy-duty components in the aerospace, automotive, and industrial sectors.

Available in hot-rolled, cold-drawn, and quenched-and-tempered conditions, 4320 alloy steel round bars can be heat-treated for increased surface hardness while maintaining core toughness. The alloy responds well to case hardening processes like carburizing, which further improves its durability and longevity in demanding applications. Additionally, its good machinability and fatigue resistance make it a preferred material for parts subjected to continuous wear and dynamic loads. With its balanced combination of strength, ductility, and machinability, 4320 alloy steel is a reliable choice for critical engineering applications.
