AISI 6150 Springs

6150 Equivalents - ASTM A29, EN 10083, JIS G4801, GB/T 3077

Durable, dependable AISI 6150 springs power industrial applications thanks to their hardness and shock-resistant properties. This chromium-vanadium spring steel is a competitive option for both tempering and oil-hardening processes. Thanks to Coiling Technologies, you can easily order custom springs using AISI 6150 steel or your chosen alloy.

Characteristics of AISI 6150 Springs

Springs manufactured with AISI 6150 are made of fine-grained, highly abrasion-resistant carbon-chromium alloy steel. This steel provides outstanding shock resistance and toughness when heat treated. When tempered, the alloy is a popular option for environments with harsh shocks and vibrations. The following technical specifications highlight the characteristics of this alloy that make it a competitive choice in many industries.
