Product Description
ASTM A29 AISI 5160 Spring Steel
1: AISI 5160 Steel Introduction
SAE 5160 steel is a silicon-manganese series alloy spring steel with high carbon content. It is an American steel grade from ASTM A29. Known for its high strength, excellent toughness, and superior fatigue resistance, SAE 5160 is widely used in the manufacture of various mechanical components that require high durability and resilience. Common applications include leaf springs, coil springs, hand tools, and blades. SAE 5160 is typically supplied in the annealed condition for forming and then heat-treated to achieve its required mechanical properties.

6: Goods available in China
If you want to purchase 5160 steel from China, you can find suppliers who can provide it in both flat bar and round bar forms. However, it is not a standard or widely stocked grade in the domestic Chinese market. This is because the domestic market predominantly uses 60CrMnA, 60Si2Mn, or other more common spring steels for similar applications. If you can accept 60CrMnA as a substitute for 5160 material, it can significantly improve availability, reduce lead time, and save cost.
