JIS SUP9 Steel

 

SUP9 steel is a type of spring steel that has high strength and durability. Here are some detailed information about SUP9 steel:

Standard: The primary standard for SUP9 steel is the Japanese standard JIS G4801.

 

Chemical composition: The chemical composition of SUP9 steel includes 0.52-0.60% carbon (C), 0.15-0.35% silicon (Si), 0.65-0.95% manganese (Mn), and the content of phosphorus (P) and sulfur (S) does not exceed 0.035%.

 

Properties: The tensile strength of SUP9 steel is 1080-1280 MPa, with a yield strength of 835 MPa and a fracture elongation of 10-20%.

 

Uses: SUP9 steel is primarily used for manufacturing various springs, such as vehicle suspension systems, industrial machinery, agricultural machinery, and railway vehicles. Due to its high strength and wear resistance, SUP9 steel can also be used to manufacture knives and blades.

 

Condition: SUP9 steel is usually supplied in the hot-rolled state, which means that it has the final characteristics during the heat treatment process.

 

Advantages: SUP9 steel has excellent elasticity and toughness, which can resist deformation and fracture. It also has good wear resistance and corrosion resistance.

 

Disadvantages: SUP9 steel is susceptible to oxidation and corrosion, so it requires proper maintenance and protection to extend its service life.

 

Common forms: SUP9 steel's common forms include round steel, flat steel, and square steel.

 

Comparison of national standards: There are differences in the spring steel grades for SUP9 steel in different countries. In China, the equivalent grade of SUP9 steel is 60Si2Mn, following the GB/T 1222 standard. In the United States, a similar steel standard is SAE 9254. Other countries also have similar spring steel grades, such as Germany's 1.5028 and the United Kingdom's EN45.

 

In summary, SUP9 steel is a type of spring steel that has high strength and durability, making it suitable for manufacturing various springs and blades. Understanding information such as standards, chemical composition, performance, uses, conditions, advantages, disadvantages, and common forms of SUP9 steel can help in selecting and applying this steel material.
