What kind of material is 8620?
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.
Is 8620 a low alloy steel?
Overview. A medium-strength, low-carbon alloy steel, 8620 contains good toughness and strength properties, along with good core strength. 8620 has a high case toughness and above average core toughness due to the nickel content. Additionally, it is the most widely used carburizing alloy steel.
