SAE 8620
Carbon Steel SAE 8620, also known as AISI 8620, is a low-alloy steel with good toughness and strength properties. It is widely used in various industries due to its excellent combination of hardenability, weldability, and machinability. Let's delve into the specifics of SAE 8620 steel:
Steel Properties
Tensile Strength: Typically ranges from 530 to 700 MPa (77 to 101 ksi) depending on the heat treatment condition.
Yield Strength: Varies widely based on the heat treatment and can range from 370 to 630 MPa (54 to 91 ksi).
Elongation: Around 15-25% in the normalized or annealed condition.
Hardness: Typically, the hardness after heat treatment ranges from 150 to 250 HB (Brinell Hardness).
Application
Automotive Industry: Gears, crankshafts, camshafts, and transmission components.
Aerospace Industry: Aircraft landing gear components, gears, and structural parts.
Machinery: Shafts, pins, bushings, and hydraulic fittings.
