Black St37 St50 Low Carbon Steel Coil Hot Rolled Steel Coil Ss400 SS300

Black St37 St50 Low Carbon Steel Coil description

St37 and St50 are both low carbon steel grades commonly used in various industries. When referring to a black St37 St50 low carbon steel coil, it means that the steel is in the form of a coil and meets the requirements specified for both St37 and St50 low carbon steel. Here is a description of a black St37 St50 low carbon steel coil:

1. Composition: St37 and St50 low carbon steel coils primarily consist of iron and a low carbon content, typically ranging from 0.06% to 0.15%. These grades may also contain small amounts of other elements such as manganese, phosphorus, sulfur, and silicon, which can vary depending on the specific grade and manufacturing process.

2. Strength and ductility: St37 and St50 low carbon steel coils offer moderate strength and good ductility. They have a minimum tensile strength of 340 to 470 MPa (St37) and 490 to 630 MPa (St50), respectively. These properties make them suitable for various structural and general engineering applications.

3. Formability: The coil form of St37 and St50 low carbon steel allows for easy processing and fabrication. They can be cut, bent, and shaped into different forms without sacrificing their structural integrity. This makes them suitable for applications that require complex shapes, such as structural components, machinery, and equipment.

4. Weldability: St37 and St50 low carbon steel coils generally offer good weldability. They can be welded using common welding methods such as arc welding, MIG (metal inert gas) welding, and TIG (tungsten inert gas) welding. However, preheating and post-weld heat treatment may be required for thicker sections or critical applications to ensure proper weld strength and minimize the risk of weld cracking.

5. Surface Finish: A black St37 St50 low carbon steel coil typically has a black oxide scale or a black finish applied to the surface. This surface finish provides some level of protection against rust and corrosion. However, additional protective coatings or treatments may be required for extended protection, especially in corrosive environments.

6. Applications: St37 and St50 low carbon steel coils find applications in various industries, including but not limited to:

   • Structural components in buildings and bridges
   • Automotive components
   • Machinery and equipment manufacturing
   • General fabrication and manufacturing
   • Pipes and tubes
   • Storage tanks
   • Construction materials

Please note that the specific properties and availability of a black St37 St50 low carbon steel coil may vary depending on the manufacturer and the specific manufacturing process. It is recommended to consult with the supplier or review the relevant specifications to ensure the desired properties and specifications are met for your specific application.
