Product Description

Product Description

AISI/SAE 8720 Steel Bar Low-Carbon Alloy Steel for Machining

AISI/SAE 8720 (UNS G87200) is a low-carbon, low-alloy structural steel containing chromium, nickel, and molybdenum. It offers excellent carburizing and hardenability, making it suitable for manufacturing components that require high strength and wear resistance. With good mechanical properties and machining characteristics in the annealed condition, AISI/SAE 8720 is commonly used in gears, shafts, and other structural parts that undergo carburizing and heat treatment.
