8620 HR Bar

Alro stocks 8620 Hot Rolled Steel. 8620 is a low carbon nickel chromium molybdenum alloy steel with good carburized properties.  The nickel content contributes to a high strength case toughness and 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.

Alro also stock 8620 CF (Cold Finish)
8620 is available in plate, rounds, flats, squares, and bars
