Nippon Alloys Inc is a 4620 Alloy Steel Round Bar Manufacturer. We make precision-engineered round bar manufactured out of low-alloy nickel-molybdenum steel and also offer 4620 alloy steel an alloy that has the properties of case hardening, and therefore it has a core that is very tough without taking away one of its vital qualities, wear resistance. These bar shaped steel are very popular in cars, planes, defense and belt industries where surface hardness and shock resistance plays a significant role. They are manufactured to various standards and are applicable in most applications where they are used in gears, crankshafts, pinions and bushings. View our trusted collection of Alloy Steel Round Bar for critical infrastructure needs.
Available on all major B2B portals, our 4620 Alloy steel round bar has an ensured dependability with demonstrated metallurgical accomplishment and easy adaptability towards carburizing besides heat treatment. These bars are aimed at bulk supply and with effective logistics in mind, so they are perfect OEMs and industrial fabricators who require core ductility and surface strength in a single solution. They are tough and easy to process and thus a reliable material in long-service-life and high-load components.
Soft for improved machinability and forming, these bars are ideal for applications requiring later case hardening, such as gear blanks and mechanical prototypes.
Pre treated with carburizing for wear resistant surface and strong core, these are used in finished components like gears, rollers, and couplings.
What makes 4620 alloy steel suitable for case hardening applications?
4620 steel has a low carbon core with alloying elements like nickel and molybdenum, enabling a soft, tough center and a hard, wear resistant surface after carburizing and quenching.
What are the common applications of 4620 round bars?
4620 alloy steel is used in gears, shafts, axles, bushings, and other components that require high surface wear resistance and a ductile core, especially in automotive and aerospace sectors.
Can 4620 alloy steel be machined and welded?
Yes, it is machinable in the annealed condition and suitable for welding, though preheating and post weld heat treatment may be required for structural integrity in critical applications.
