S45C Steel Plate

S45C is a medium carbon steel grade. It is characterized by good strength and hardness properties, as well as excellent machinability and weldability. S45C steel plates are commonly used in industrial applications such as manufacturing machinery, automotive parts, construction equipment, and tools. The chemical composition of S45C includes 0.42-0.48% carbon, 0.60-0.90% manganese, 0.15-0.35% silicon, 0.03% phosphorus, 0.035% sulfur, and 0.4% iron. The mechanical properties of S45C include a tensile strength of 570-700 MPa, yield strength of 330-470 MPa, elongation of 20-25%, and reduction of area of 45-60%. S45C steel plates are available in different sizes and thicknesses, and can be customized based on the specific requirements of the application.

The following are the main points of S45C steel plate product specifications:

1. Excellent corrosion resistance: containing more chromium, molybdenum and other alloying elements, can effectively improve the corrosion resistance of the steel plate.

2. Cost-effective: Compared with high-grade alloy steel, S45C steel plate is more affordable, and can be widely used in many industrial fields.

3. Good machinability: with high strength, excellent machinability and plasticity, it can meet the needs of mechanical parts manufacturing.

4, high tensile strength: tensile strength can reach 600-750MPa, is the ideal strength and durability requirements of the material.
