00Cr24Ni6Mo3N is a super austenitic stainless steel, which is a two-phase austenitic-ferritic stainless steel. It is a kind of dual-phase stainless steel with a very wide range of uses. Not only does it have excellent chemical and mechanical properties, but its weldability and plasticity are also very good.

00Cr24Ni6Mo3N is composed of austenite and ferrite. The carbon content of the steel is slightly higher than Mo-free super austenitic steel, so it has a lower alloying cost. Compared with Mo-free super austenitic steel, the corrosion resistance of 00Cr24Ni6Mo3N is improved significantly by adding Mo. Therefore,

The material is resistant to pitting and crevice corrosion in chloride media (also known as intergranular corrosion).Owing to its good resistance to chloride stress corrosion cracking,it is an ideal material for oil refining equipment and other anti-corrosion industry. In addition, the steel has good comprehensive properties, good weldability and plasticity, good forming performance and excellent toughness, which can effectively reduce the structure vibration and its sound transmission performance, so it is widely applied in paper making and other industries.

00Cr24Ni6Mo3N stainless steel is suitable for a wide range of applications,such as seawater equipment, chemical and petrochemical plants, pharmaceutical and food production equipment, gas turbines and evaporators, as well as automotive exhaust pipes, marine and offshore structural components, etc.
