Dive into the Characteristics and Performance of 403S17 Steel Grade

The 403S17 steel grade is a martensitic stainless steel that contains chromium, nickel, and other elements. It is known for its high strength, hardness, and corrosion resistance.

The mechanical properties of the 403S17 steel grade include its yield strength, tensile strength, impact strength, and hardness. These properties make it suitable for various applications where strength and durability are required, such as automotive components, cutlery, surgical instruments, and industrial equipment.

The yield strength of 403S17 steel grade is typically around 275 MPa, while its tensile strength can range from 550 to 770 MPa. The impact strength is generally above 100 J, indicating its ability to withstand sudden shocks or impacts. The hardness of this steel grade ranges from 25 to 35 HRC (Rockwell hardness scale), which indicates its ability to resist deformation and wear.

The chemical composition of the 403S17 steel grade includes elements such as carbon, manganese, phosphorus, sulfur, silicon, chromium, and nickel. The specific composition may vary based on different manufacturing processes and required properties. The typical chemical composition of 403S17 steel grade is as follows:

– Carbon (C): 0.08-0.15%
– Manganese (Mn): 1.00% max
– Phosphorus (P): 0.040% max
– Sulfur (S): 0.030% max
– Silicon (Si): 1.00% max
– Chromium (Cr): 11.50-13.50%
– Nickel (Ni): 0.60-0.90%

The 403S17 steel grade is commonly used in industries such as:

1. Automotive: It is used in the production of automotive components, such as exhaust systems, engine parts, and fasteners, due to its high strength and corrosion resistance.
