Detailed introduction to JIS G3131 SPHC steel coil

JIS G3131 SPHC steel coil is the Japanese Industrial Standard specification for hot-rolled general-purpose steel plates or steel coils. This steel is commonly used in general forming, stamping, bending and welding applications and has good machinability properties.

The chemical composition of JIS G3131 SPHC steel coil is usually strictly controlled to ensure that its mechanical properties meet the requirements. These steel coils have been hot-rolled during the production process, and there is usually a layer of oxide scale on the surface, which needs to be removed through corresponding surface treatment methods.

Standard specifications and dimensions are developed in accordance with JIS G3131 standards to meet the needs of different industries and application fields. In terms of quality control, steel coils must comply with relevant standards and undergo strict inspections to ensure that their quality and performance meet specified requirements.

The typical chemical composition and mechanical properties of JIS G3131 SPHC steel coil are as follows:

Chemical composition (typical values):
- Carbon content (C): 0.15% or less
- Manganese content (Mn): 0.60% or less
- Silicon content (Si): 0.05% or less
- Sulfur content (S): 0.05% or less
- Phosphorus content (P): 0.05% or less

Mechanical properties (typical values):
- Yield strength: 270 MPa
- Tensile strength: 27 kgf/mm² (265 N/mm²)
- Elongation: more than 27%

These values are typical reference values, and the specific chemical composition and mechanical properties should be determined according to the actual manufacturer and product specifications. JIS G3131 SPHC steel coil generally have good processability and are suitable for general forming, stamping, bending and welding applications.

JIS G3131 SPHC steel coil is widely used in automobile manufacturing, home appliance manufacturing, construction industry and other fields, and the market demand is stable. With the advancement of industrialization and the continuous development of technology, the application of this steel in various industries is also expanding and deepening.
