PRODUCT DESCRIPTION
PRODUCT INTRODUCTION
60Si2Mn alloy steel sheet is a high-quality spring steel containing silicon and manganese, designed for parts that require high elasticity, yield strength, and long-term fatigue resistance. This grade is widely recognized under the Chinese GB/T 1222 standard and is equivalent to JIS SUP7 or AISI 9260 in international standards.
The alloy composition, especially its high silicon content, enhances its hardenability and spring performance, making it ideal for heat treatment processes like quenching and tempering. This steel sheet provides a good balance of strength and ductility, allowing it to withstand repeated mechanical stress.
Key Features:
Grade: 60Si2Mn / GB/T 1222
High elastic limit and tensile strength
Excellent fatigue resistance under cyclic loading
Good hardenability after heat treatment
Machinable in annealed state
Available in hot rolled or cold drawn sheets
PRODUCT APPLICATION
60Si2Mn steel sheets are widely used for manufacturing spring-type components that operate under high stress and require excellent return elasticity. Common application areas include:
Automotive suspension leaf springs
Coil springs and torsion springs
Agricultural machinery parts
Rail vehicle suspension systems
Clutch parts and elastic washers
Engineering tools and wear-resistant components
Thanks to its combination of high yield strength and fatigue resistance, 60Si2Mn is a reliable material for parts that must endure long-term vibration or dynamic load conditions.
