Uncovering the Properties and Uses of 403S17 Steel Grade

[ad_1] 403S17 is a stainless steel grade that is commonly used in mechanical and structural applications due to its excellent combination of mechanical properties and corrosion resistance. It is a martensitic stainless steel with a chromium content of 12-14% and a carbon content of 0.15-0.22%, as well as small amounts of manganese, silicon, phosphorus, sulfur, and other elements.

The technical properties of 403S17 steel grade include high tensile strength, good hardness, and moderate ductility. It has a maximum tensile strength of 600-750 MPa and a maximum hardness of 192 HB. This makes it suitable for a wide range of applications such as shafts, gears, bearings, and other structural components where high strength and corrosion resistance are required.

The chemical composition of 403S17 steel grade is as follows:
– Carbon: 0.15-0.22%
– Chromium: 12-14%
– Manganese: 1% max
– Silicon: 1% max
– Phosphorus: 0.04% max
– Sulfur: 0.03% max
– Iron: Balance

The high chromium content in 403S17 steel grade provides excellent corrosion resistance, making it suitable for use in mildly corrosive environments. It is not recommended for use in highly corrosive environments or at high temperatures, as it does not have the same level of corrosion resistance as austenitic or duplex stainless steels.

In conclusion, 403S17 steel grade is a versatile stainless steel with excellent mechanical properties and corrosion resistance, making it suitable for a wide range of mechanical and structural applications. However, its use should be limited to mildly corrosive environments and moderate temperatures.
