8670 Steel
SAE 8670 is a tough, low-alloy steel valued for its capacity to absorb impact, resist wear and serve in heavy-duty environments. It is particularly suited for components where impact, shock or cyclic loads are significant.
grades designations
SAE 8670 typical composition includes carbon, nickel, chromium, molybdenum, manganese, silicon and trace phosphorus and sulfur levels controlled for toughness performance.
SAE 8670 Characteristics
Property
specification
Weldability
SAE 8670 provides good weldability when used in the annealed or normalized condition.
Thermal Cutting
Careful control of heat input and cooling is crucial to avoid formation of brittle zones along the cut edge.
Bendability
8670 exhibits reasonable formability and bendability for shaping and fabrication in the annealed or as-rolled condition.
Ease of Fabrication
SAE 8670 is machinable and formable especially when supplied in the annealed condition.
