Stamping and Forming Parts:
Suitable for high precision parts such as washer, shims, bracket, clips and other deformed products which is needed flexibility and dimension stability.
Auto Parts:
It’s best known for being used in suspension components, clutch springs, brake springs and seat belt parts.
Civil /Structural Engineering:
Also for high strength and tough fasteners, wire forms, and building block parts that you can depend on.
Industrial Equipment:
Used in safety valve springs, conveyor system components, vibration attenuators, and machinery parts subjected to unique continuous loads.
Consumer Products:
As part of durable lock mechanisms, measuring tape, hand tools, home appliances and more, its long spring life keeps products moving.
Molten Iron Pretreatment:
Magnesium-based desulfurization was performed to lower sulfur content and enhance steel clean attractiveness to achieve superior mechanical properties and good reliability.
Converter Steelmaking:
The combined blowing of the upper and lower blowing converter process refines molten steel and precisely controls the chemical composition, purity and evenness of steel.
Alloying & LF Refining:
The content of carbon, manganese, silicon and other alloying elements is accurately adjusted according to the requirements of GB 60 steel. LF refining de-burrs and enhances interior; quality.
Calcium Feeding & Soft Blowing:
Calcium treatment alters non-metallic inclusions and the soft blowing also adds on uniform temperature and composition for whole ms. steel.
Continuous Casting:
The refined steel is then continuously cast into medium and wide conventional slabs with good internal structure and dimensional accuracy.
Slab Heating & Rolling:
Cast slabs are reheated in the heating furnace and then rough rolled in 5 passes and finally rolled in 7 passes controlled rolling condition to achieve the final thickness, the desired strength and surface quality.
Controlled Cooling & Coiling:
Upon rolling, the steel sheet is subjected to laminar flow cooling to refine the microstructure and mechanical properties and coiled.
Packaging:
Completed GB 60 spring steel strips are examined tightly, rust protected, and safe packaged to be transported for worldwide customers.
1. Excellent Mechanical Properties
High Elastic Limit and Yield Strength:
After heat treatment, GB 60 Spring Steel Strip achieves high elastic limit and yield strength, allowing it to quickly return to its original shape under repeated loading and deformation. It is ideal for springs and elastic components requiring stable performance.
Outstanding Fatigue Resistance:
The material maintains excellent performance under continuous vibration, tension, and compression cycles, reducing the risk of fatigue failure and extending service life in demanding applications.
Balanced Hardness and Toughness:
GB 60 steel provides sufficient hardness to resist deformation while maintaining good toughness to prevent brittle fracture, ensuring reliable performance under complex working conditions.
2. Excellent Processing and Forming Performance
Good Cold Working Ability:
The strip can be processed through cold rolling, stamping, bending, and winding to manufacture coil springs, flat springs, spring clips, and other precision components with accurate dimensions.
Stable Heat Treatment Performance:
Through controlled quenching and tempering processes, the hardness, strength, and elasticity of GB 60 Spring Steel Strip can be adjusted to meet different application requirements.
Reliable Fabrication Performance:
Suitable for various manufacturing processes, providing flexibility for customized spring components and industrial applications.
3. Wide Application Range
GB 60 Spring Steel Strip offers a cost-effective solution for many industries due to its excellent elasticity and strength. It is commonly used in general mechanical springs, automotive components, industrial equipment, and precision elastic parts.
Compared with alloy spring steels such as 50CrVA and 60Si2Mn, GB 60 provides reliable performance for medium-stress applications, while alloy grades are preferred for higher fatigue strength, heat resistance, and heavy-duty working conditions. Its versatility makes it suitable for both general industrial products and specialized mechanical components.
Usually bare package
Packaging
Cardboard Tube Packaging:
GB 60 Spring Steel Strips are fixed on strong cardboard tubes with two ends covered and sealed to avoid surface become of harm in transit.
Plastic Strapping Packaging:
Steel coils are tied up by strong plastic straps together with end protection and wrapping to hold the coil stability and protect from deforming.
Cardboard Protection Packaging:
Cardboard Cleat and edge protectors can be use in protecting coil surface and edges from scrathes, impact and damage from handling.
Steel Strap Packaging:
Heavy-duty iron buckle or steel strap package for the strong fixation in long distance export shipping.
All of the above packaging are based on the premise that the steel coils will be safely, moisture-proof, rust-proof and damage-proof whether in storage or in transportation.
