Worldwide Equivalents Of Grade S45C

S45C is a Japanese standard grade of carbon steel. It stands for "S" steel, "45" refers to the carbon content, and "C" indicates that it is a carbon steel. S45C has good mechanical properties, including high tensile strength and hardness. It is commonly used in the manufacturing of machine parts, gears, and shafts.

Note that the chemical composition and mechanical properties may vary slightly between different standards and grades, so it's important to consult the specific standards/specifications for each application.

1. AISI 1045 – This is the American equivalent of S45C. It is a carbon steel that can be heat treated to produce good surface hardness and wear resistance. It is commonly used for machinery parts and shafts.

2. DIN 1.1191 – This is the German equivalent of S45C. It is a carbon steel that is characterized by its good strength and toughness properties. It is commonly used for shafts, gears, and other machinery components.

3. JIS S50C – This is a higher grade of carbon steel compared to S45C. It has better mechanical properties, such as higher hardness, toughness, and wear resistance. It is commonly used for die casting, injection molds, and other precision machinery parts.

4. GB 45 – This is the Chinese equivalent of S45C. It is a carbon steel that is commonly used for general machinery parts and components. It has good machinability, weldability, and heat treatment properties.

5. EN8 – This is the British equivalent of S45C. It is a medium carbon steel that is commonly used for axles, shafts, and other machinery components. It has good strength, toughness, and machinability properties.

Chemical Composition

JIS Steel S45C Common Available Shapes

1. Round Bar: available in round bars ranging from 5mm to 250mm in diameter. These bars are used in the manufacturing of shafts, gears, and hydraulic cylinders.

2. Flat Bar: available in flat bars ranging from 10mm to 200mm in width and 3mm to 150mm in thickness. These bars are used in the production of mold bases, dies, and industrial tools.

3. Plate/Sheet: available in plate and sheet forms with a thickness ranging from 2mm to 300mm. These are used in the production of molds, jigs, and machine parts.

4. Square Bar: available in square bars ranging from 10mm to 200mm in size. These bars are used in the production of machine parts, forging dies, and hydraulic components.

5. Hexagonal Bar: available in hexagonal bars ranging from 5mm to 100mm in size. These bars are used in the production of nuts, bolts, and other fasteners.
