8620 Steel
SAE 8620 is a low-alloy, case-hardening steel known for its excellent combination of surface wear resistance and core toughness. This grade is engineered for applications which require a hard outer layer and a ductile, shock-resisting core.
grades designations
The alloying elements of SAE 8620 provide the grade’s capacity for carburizing, depth of hardening, and core strength.
SAE 8620 Mechanical and Physical Properties
Property
specification
Weldability
SAE 8620 offers good weldability.
Thermal Cutting
When thermally cutting (laser, plasma or oxy-fuel) SAE 8620 material, managing heat input and cooling is critical to prevent unintended hardening or brittleness at the cut edge.
Bendability
In the annealed or normalized state, SAE 8620 shows good formability and bendability for general fabrication.
Ease of Fabrication
SAE 8620 is broadly machinable and formable in the annealed or normalized state.
