GB 60 spring steel strip, also known as 60G steel, is a high carbon steel strip commonly used to manufacture various types of springs, coil springs, and flat springs. Here are the details of GB 60 spring steel strip:
Material: GB 60 spring steel strip is a high carbon steel with a carbon content of approximately 0.60-0.61%. It also contains small amounts of manganese, silicon, and other elements to enhance its mechanical properties.
Thickness: GB 60 spring steel strip is available in a variety of thicknesses, typically ranging from 0.1 mm to 3.0 mm, depending on the specific requirements of the application.
Width: The width of GB 60 spring steel strip can vary depending on the intended use, typically ranging from 5 mm to 300 mm.
Surface treatment: The steel strips are usually provided with a standard surface treatment provided by the hot rolling process. However, they can also be further processed to achieve a specific surface treatment as per the customer's requirements.
Hardness: GB 60 spring steel strip is heat treated to achieve the required hardness, which is typically in the range of 42-47 HRC (Rockwell hardness scale).
Tolerances: Close tolerances are maintained to ensure uniform thickness and width throughout the length of the strip, in accordance with industry standards and customer specifications.
It is important to note that the details of GB 60 spring steel strip may vary depending on the specific requirements and standards of the application. Therefore, it is recommended to consult us to ensure that the strip meets the necessary standards and performance criteria for the intended use.

Springs: These strips are widely used in the manufacturing of coil springs, flat springs, and various types of mechanical springs used in automotive, aerospace, industrial machinery, and consumer goods.
Blades and Cutting Tools: Spring steel strips are utilized in the production of saw blades, knives, cutting tools, and shear blades due to their high strength, wear resistance, and ability to maintain sharp edges.
Stamping and Forming: They are employed in stamping and forming operations to produce precision components, such as washers, shims, brackets, and clips, where their elasticity and formability are essential.
Automotive Components: Spring steel strips are used in the automotive industry for applications such as suspension components, clutch springs, brake springs, and seat belt components due to their ability to withstand high stress and fatigue.
Construction and Engineering: These strips are utilized in construction and engineering applications for manufacturing various types of fasteners, wire forms, and structural components that require high strength and resilience.
Industrial Equipment: They find use in industrial equipment and machinery for applications such as safety valve springs, conveyor belt components, and vibration damping devices.
Consumer Goods: Spring steel strips are used in the production of consumer goods such as lock mechanisms, measuring tapes, hand tools, and various household appliances.

1. Excellent Mechanical Properties to Meet Elasticity Requirements
High elastic limit and yield strength: After heat treatments such as quenching and tempering, spring steel strip maintains an extremely high elastic limit (the maximum stress before permanent deformation occurs). It quickly recovers to its original shape when subjected to repeated loads or deformation, ensuring stable elastic function in springs and other components (such as automotive shock absorber springs and return springs in precision instruments).
Excellent fatigue strength: Under long-term alternating loads (such as mechanical vibration and repeated tension/compression), it is less susceptible to fatigue fracture and has a long service life. For example, automotive valve springs must withstand thousands of reciprocating movements per minute, and the high fatigue resistance of spring steel strip is crucial for its reliable operation.
A balanced hardness and toughness: It possesses sufficient hardness to resist plastic deformation while maintaining a certain toughness to avoid brittle fracture, adapting to complex operating conditions (for example, elastic components operating in low-temperature environments require both hardness and low-temperature toughness).
2. Excellent Processing and Forming Properties
Excellent Cold Working Properties: Various complex shapes (such as coil springs, leaf springs, wave springs, and spring collars) can be formed through cold working processes such as cold rolling, stamping, bending, and winding. The finished product offers high dimensional accuracy (small thickness deviation and smooth surface), eliminating the need for extensive post-processing.
Stable Heat Treatment Processability: By adjusting parameters such as quenching temperature and tempering time, the material's hardness, elasticity, and other properties can be precisely controlled to meet the diverse elasticity requirements of different applications (for example, high-precision instrument springs require more precise performance control).
Weldability and Splicing: Some spring steel strips (such as low-alloy spring steel) can be welded together, making them suitable for the manufacture of large or custom-shaped elastic components, broadening their application range.
3. Diverse Material Options to Adapt to Different Applications
The composition and properties of spring steel strips can be adjusted according to specific needs. Common types include:
Carbon spring steel (such as 65Mn and 70# steel): Low cost and excellent elasticity make them suitable for low-stress springs in general machinery (such as mattress springs and clamp springs). Alloy spring steel (such as 50CrVA and 60Si2Mn): The addition of alloying elements such as chromium, vanadium, silicon, and manganese enhances fatigue strength and heat resistance, making it suitable for high-stress, high-temperature environments (such as automotive suspension springs and turbine valve springs).
Stainless steel spring steel (such as 304 and 316): It combines elasticity and corrosion resistance, making it suitable for humid, acidic, and alkaline environments (such as medical device springs and elastic components in marine equipment).
This diversity enables it to meet a wide range of needs, from general civilian applications to high-end industrial applications.

How to pack steel coils
1. Cardboard tube packaging: Place the Hot Roll Steel Coil in a cylinder made of cardboard, cover it at both ends, and seal it with tape;
2. Plastic strapping and packaging: Use plastic straps to bundle the Carbon Steel Coil into a bundle, cover them at both ends, and wrap them with plastic straps to fix them;
3. Cardboard gusset packaging: Fasten the steel coil with cardboard cleats and stamp both ends;
4. Iron buckle packaging: Use strip iron buckles to bundle the steel coils into a bundle and stamp both ends
In short, the packaging method of steel coils needs to take into account the needs of transportation, storage and use. The steel coil packaging materials must be strong, durable and tightly tied to ensure that the packaged steel coils will not be damaged during transportation. At the same time, safety needs to be paid attention to during the packaging process to avoid injuries to people, machinery, etc. due to packaging.
