Why Use 8620 Chromoly?

8620 alloy steel has a much higher carbon content than mild steel which translates into increased strength. This material is characterized by a hard outer surface, combined with a ductile interior for higher strength. Minimum properties of 8620 (chrome-nickel-moly) alloy steel; Tensile Strength, psi: 97,000 Yield, psi 57,000.  What does this mean for you? Our 8620 chromoly parts can take more abuse day in and day out than our competition, ask anyone who uses them.
