SUP11 Spring Steel Bar

 

SUP11 steel is a type of spring steel with the following specific information:

Standard: The primary standard for SUP11 steel is the Japanese standard JIS G4801.

 

Chemical composition: The chemical composition of SUP11 steel includes carbon (C) ranging from 0.56-0.64%, silicon (Si) ranging from 1.80-2.20%, manganese (Mn) ranging from 0.70-1.00%, and the content of phosphorus (P) and sulfur (S) does not exceed 0.035%.

 

Properties: SUP11 steel has a tensile strength of 1275-1420 MPa, a yield strength of 1180 MPa, and a fracture elongation of 9%.

 

Uses: SUP11 steel is primarily used for manufacturing high-strength springs, such as automotive suspension systems, industrial machinery, and agricultural machinery.

 

Condition: SUP11 steel is usually supplied in the hot-rolled state, which means it has the final characteristics during the heat treatment process.

 

Advantages: SUP11 steel has high strength and good corrosion resistance.

 

Disadvantages: SUP11 steel is susceptible to oxidation and corrosion, so proper maintenance and protection are required to extend its service life.

 

Common forms: Common forms of SUP11 steel include round steel, flat steel, and square steel.

 

Comparison of national standards: There are slight differences in the spring steel grades for SUP11 steel in different countries. For example, in China, the equivalent grade to SUP11 steel is 60Si2CrA, following the GB/T 1222 standard. In Europe, similar steel standards include EN 10089, and in the United States, the equivalent steel standard is AISI 9260.

 

In summary, SUP11 steel is a high-strength spring steel with excellent strength and corrosion resistance. Understanding its standards, chemical composition, properties, uses, condition, advantages, disadvantages, and common forms can help in selecting and applying this steel material.
