Understanding the Composition and Properties of 434S17 Steel Grade

[ad_1] The 434S17 steel grade is a martensitic stainless steel that is commonly used in applications where high strength and good corrosion resistance are required. The chemical composition of 434S17 steel typically includes the following elements:

– Carbon (C): 0.12-0.17%
– Silicon (Si): 1.00% max
– Manganese (Mn): 1.00% max
– Phosphorus (P): 0.040% max
– Sulfur (S): 0.030% max
– Chromium (Cr): 16.00-18.00%
– Nickel (Ni): 0.50% max

The mechanical properties of 434S17 steel typically include:

– Tensile strength: 650-850 MPa
– Yield strength: 350-450 MPa
– Elongation: 15-20%
– Hardness: 20-25 HRC

The combination of its chemical composition and mechanical properties makes 434S17 steel suitable for a wide range of applications, including automotive components, industrial equipment, and tools where high strength and corrosion resistance are crucial. It is important to consult the specific standards and specifications for the required properties and composition for any particular application.
