Material: 65Mn is a high carbon manganese spring steel with a carbon content of 0.62-0.70% and a manganese content of 0.90-1.20%. This composition provides excellent yield strength and elasticity, making it suitable for spring applications.
Thickness: 65Mn 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 65Mn 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: 65Mn spring steel strips are heat-treated to achieve the desired hardness, typically in the range of 44-48 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.

Welded pipe, also known as welded steel pipe, is basically a steel pipe made of steel plate or strip steel after crimping and welding.
Welded pipes are mainly used for boilers, automobiles, ships, light-weight door and window steel for construction, furniture, various agricultural machinery, scaffolding, wire threading pipes, high-rise shelves, containers, etc.
Welded pipes are classified according to their uses: according to their uses, they are divided into general welded pipes, galvanized welded pipes, oxygen-blown welded pipes, wire casings, metric welded pipes, idler pipes, deep well pump pipes, automotive pipes, transformer pipes, electric welding thin-walled pipes, electric welding Special-shaped pipes and spiral welded pipes.

Characteristics of Hot Rolling Carbon Steel Coil
1. High strength: Steel coils have high strength and can withstand larger loads.
2. Corrosion resistance: The surface of the steel coil has been specially treated, so it can be used in different environments and climate conditions and has good corrosion resistance.
3. Easy to process: Steel coils can be processed into various shapes to adapt to different use needs.
4. Low cost: The price of steel coils is relatively low, which is more cost-effective than some other materials.
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?
