JIS S20C Carbon Steel

JIS S20C carbon steel is a mild steel with a carbon content of 0.18% to 0.23%. It is typically used in the manufacturing of machine parts, rods, and bars. The S20C designation refers to the Japanese Industrial Standard (JIS) for carbon steel grades.

S20C carbon steel has good weldability, machinability, and ductility. It is often used for parts that don't require high strength or hardness, such as gears, shafts, and bolts. S20C also has good wear resistance and can be surface hardened to improve its properties.

Additionally, S20C carbon steel is easily processed as it can be cut, formed, and shaped using a variety of welding and machining techniques. Its affordability and versatility make it a popular choice for many manufacturing applications.

Overall, JIS S20C carbon steel is a reliable and cost-effective option for a wide range of industrial applications.

• Chemical composition: chemical composition includes carbon (C) content between 0.18-0.23%, manganese (Mn) content between 0.3-0.6%, sulfur (S) and phosphorus (P) content are not more than 0.05%.
• Mechanical properties:  excellent mechanical properties, and its tensile strength is (41~65)kgf/mm², yield strength is (21~44)kgf/mm², and elongation is between (16~29)%.
• Welding performance:  good welding performance, and can be welded by common welding methods such as arc welding and argon arc welding.
• Heat treatment performance:  good heat treatment performance, suitable for normalizing, quenching, tempering and other heat treatment processes, and can produce parts with high strength and good toughness.
• Application:used in manufacturing machinery, automobiles, ships, chemical and other fields of parts, such as shafts, pins, coil springs, sprockets and so on.
