347 Stainless Steel Bar

347 Stainless Steel Bar

347 stainless steel is a niobium-stabilized austenitic stainless steel that offers excellent resistance to intergranular corrosion, especially after welding, and superior performance at high temperatures. The addition of niobium prevents carbide precipitation, maintaining its corrosion resistance in elevated temperatures (up to 800°C). It also exhibits good general corrosion resistance and oxidation resistance. 347 is commonly used in aerospace, chemical processing, and high-temperature exhaust systems.

Type of Stainless Steel:

Stainless steel is divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and duplex stainless steel according to the structure state.

Austenitic Stainless Steel

stainless steel with an austenitic structure at room temperature. Steel contains Cr≈18%, Ni≈8%-25% and C≈0.1%. Steel has high toughness and plasticity, but low strength.

Martensitic Stainless Steel

A steel whose mechanical properties can be adjusted by heat treatment. It has different strength and toughness at different tempering temperatures.

Duplex Stainless Steel

Austenitic and ferrite each account for about half of the structure. When the C content is low, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Si, Nb, Ti, and N. This type of steel has the characteristics of austenitic and ferritic stainless steel

 

Ferritic Stainless Steel

It contains 15% to 30% chromium and has a body-centered cubic crystal structure. This type of steel generally does not contain nickel, and sometimes contains a small amount of Mo, Ti, Nb and other elements. This type of steel has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance.

Austenitic Stainless Steel 201, 301, 304, 305, 310, 314, 316, 321, 347, 370, etc
Martensitic Stainless Steel 410, 414, 416, 416, 420, 431, 440A, 440B, 440C, etc
Duplex Stainless Steel S31803, S32101, S32205, S32304, S32750, etc
Ferritic Stainless Steel 429, 430, 433, 434, 435, 436, 439, etc
