The application of the first generation of duplex stainless steel began in the 1930s, and its typical representatives are Type 329 (S32900) and Uranus 50 (S32404).

Under normal circumstances, the ferritic content in austenitic stainless steel is 50%-60%, while the ferritic content in duplex stainless steel is higher, up to more than 75%.

420 stainless steel is a kind of Martensitic stainless steel, with certain wear resistance and corrosion resistance, high hardness characteristics, suitable for all kinds of precision machinery, beari

Grade 440C stainless steel is a high carbon steel that, after heat treatment, can achieve the highest hardness, wear resistance and strength of all stainless steel grades.

430 stainless steel: In the industry is known as "stainless iron", because it is a kind of ferritic stainless steel, has good corrosion resistance, has excellent thermal conductivity than austenitic s

What material is 904L alloy? Based on a 20% chromium and 25% nickel content, 904L is a higher alloying austenitic stainless steel that has been developed for applications containing dilute liu acids.

904L is a high alloyed austenitic stainless steel with a very low carbon content.

440C high-strength cutting tool steel, slightly higher carbon content, after appropriate heat treatment can obtain high yield strength, hardness can reach 58HRC, is one of the hardest stainless steel.

In our daily life, stainless steel is a very common product material, like what stainless steel POTS and pans are often used in daily life. The use of stainless steel is very wide, small to stainless

The corrosion resistance of stainless steel is mainly the result of chromium content. A stable layer of chromium oxide is formed on the surface of the steel to prevent chemical reactions with large ch

400 series stainless steel is an alloy of iron, carbon and chromium. Because it does not contain nickel, it is a nickel-free stainless steel, also known as stainless iron.

2205 is a grade of stainless steel, stainless steel according to the classification of microstructure can be divided into: martensitic steel, ferritic steel, austenitic steel, austenitic ferritic (dup
