HOT ROLLED 8620 BAR

CHARACTERISTICS

Hot rolled (HR) 8620 bar is a low carbon nickel chromium molybdenum alloy is a low cost steel with good carburized properties. The nickel content contributes to case toughness at high strength with above average core toughness. The chromium and molybdenum support the proper formation of carbides resulting in good surface hardness and wear. It is the most widely used carburizing alloy.

APPLICATIONS

Typical applications for hot rolled 8620 steel bar include gears, pinions, shafts, and other applications where it is helpful to have a steel that can be readily machined and carburized to controlled case depths.

8620 ALLOY ROUND BAR

Alloy 8620 is a hardenable chromium, molybdenum, nickel, low alloy carburizing steel developed for case-hardening. Through case-hardening it develops good wear characteristics. It has good forming qualities and may be welded using conventional welding methods. 8620 can be machines before carburizing and only finish machining after heat treatment of carburizing, usually limited to grinding. It has a tensile strength of 97,000PSI and yield strength of 57,000 PSI with elongation of 25%. 8620 also has good fatigue resistance. It is commonly used for carburized gears, pinions, shafts, bearings, piston rings, ring gears, crankshafts, etc.

8620 Steel Round Bar

8620 Steel is a carburizing alloy steel that can be used in a variety of medium strength applications. In addition, 8620 steel is provided in Hot Roll condition or HR. It's a low Carbon, Ni - Cr - Mo (Nickel Chromium Molybdenum) alloy. Generally a lower cost steel which helps in cutting down on material costs. Flexible hardening treatments allow optimization of core properties. Some applications for this alloy include gears, shafts and any other application that requires steel that's readily machined. Alloy 8620 is furnished in Aircraft Quality.
