Grade and Standard

Chinese Standard: GB/T 1222-2016 (Spring Steel)

Grade Interpretation:

60: Average carbon content 0.60%

Si2: Silicon content 1.50 - 2.00% (Core strengthening element)

Mn: Manganese content 0.60 - 0.90% (Improves hardenability)

International benchmarking:

USA: ASTM: AISI 9260 (similar composition)

Japan: JIS: SUP7 (similar performance)

Product Features:
High strength and high elastic limit: After heat treatment (quenching + tempering), the steel wire has extremely high strength and elasticity, and can withstand a long-term repeated stress working environment.
Good fatigue performance: Suitable for manufacturing precision springs or heavy-duty springs used under high-frequency vibration or impact.
Good heat treatment performance: It has good hardenability and can adjust the hardness and strength level according to customer needs.
Strong wear resistance and long life: The surface can be further treated by shot peening, phosphating, coating, etc. to improve wear resistance and corrosion resistance.

Product Application:

Automobile suspension springs, railway fastener springs, and mechanical valve springs
