Understanding the Chemical Composition and Mechanical Properties of 35S20 Steel Grade

[ad_1] The 35S20 steel grade is a low carbon, free-cutting steel that is commonly used in the production of precision components such as gears, bolts, and shafts. Its chemical composition typically includes the following elements:

– Carbon (C): 0.32-0.39%
– Silicon (Si): 0.15-0.35%
– Manganese (Mn): 1.3-1.7%
– Phosphorus (P): 0.08% max
– Sulfur (S): 0.08-0.15%

The mechanical properties of 35S20 steel grade are as follows:

– Tensile strength: 600-700 MPa
– Yield strength: 350-400 MPa
– Elongation: 9-12%
– Hardness: 190-220 HB

These properties make 35S20 steel grade suitable for applications that require good machinability and wear resistance. It can be easily machined and provides good surface finish, making it a popular choice in the automotive, machinery, and manufacturing industries.
