Material: GB 55Si2Mn spring steel strip is a high silicon-manganese spring steel with a carbon content of about 0.52-0.60%, silicon content of 1.50-2.00%, and manganese content of 0.60-0.90%. The addition of silicon and manganese enhances the hardenability and elastic properties of the steel.
Thickness: GB 55Si2Mn spring steel strips are available in various thicknesses, typically ranging from 0.1mm to 3.0mm, depending on the specific requirements of the application.
Width: The width of GB 55Si2Mn spring steel strips can vary based on the intended use, commonly ranging from 5mm to 300mm.
Surface Finish: The strips are usually supplied with a standard surface finish resulting from the hot rolling process. However, they can also be further processed to achieve specific surface finishes as per the customer’s requirements.
Hardness: GB 55Si2Mn spring steel strips are heat-treated to achieve the desired hardness, typically in the range of 42-47 HRC (Rockwell hardness scale) after heat treatment.
Tolerance: Precision tolerances are maintained to ensure uniform thickness and width across the entire length of the strip, meeting 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.

The advantages of spring steel strips include:
High Yield Strength: Spring steel strips are designed to withstand high stress and deformation while maintaining their shape and elasticity. This high yield strength allows them to be used in various types of springs and components that require resilience and durability.
Excellent Elasticity: Spring steel strips exhibit excellent elastic properties, enabling them to return to their original shape after being subjected to deformation. This characteristic is crucial for applications where repeated bending or flexing is required.
Good Fatigue Resistance: Spring steel strips are engineered to resist fatigue failure, making them suitable for applications involving cyclic loading and prolonged use without experiencing a loss of performance.
Wide Range of Applications: These strips are utilized in a diverse range of industries, including automotive, aerospace, construction, and manufacturing, where their high strength and resilience are essential for various components and assemblies.
Customizable Properties: Spring steel strips can be heat-treated and processed to achieve specific hardness, surface finish, and dimensional tolerances, allowing for customization to meet the unique requirements of different applications.
Cost-Effective: Spring steel strips offer a cost-effective solution for applications that demand high performance and reliability, as they provide long-term durability and reduced maintenance requirements.
Usually bare package
Transportation: Express (Sample Delivery), Air, Rail, Land, Sea shipping (FCL or LCL or Bulk)
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.
Q: Are u a manufacturer?
A: Yes, we are a manufacturer. We have our own factory located in Daqiuzhuang Village, Tianjin City, China. Besides, we cooperate with many state-owned enterprises, such as BAOSTEEL, SHOUGANG GROUP, SHAGANG GROUP,etc.
Q: Can I have a trial order only several tons?
A: Of course. We can ship the cargo for u with LCL serivece.(Less container load)
Q: Do u have payment superiority?
A: For big order, 30-90 days L/C can be acceptable.
Q: If sample free?
A: Sample free, but the buyer pays for the freight.
Q: Are you gold supplier and do trade assurance?
A: We seven years cold supplier and accept trade assurance.
