Is OCr17Ni12Mo2N stainless steel magnetic? 

OCr17Ni12Mo2N type stainless steel is non-hardenable with 0.08% carbon content. Austenitic steel. It has higher strength than conventional Type 316, has good corrosion resistance to most chemicals, salts and acids, and lasts well in marine environments. OCr17Ni12Mo2N type stainless steel was developed for primary forming into wrought products. Although it is non-magnetic annealed, when cold worked it becomes quite magnetic. It has similar processability to 302 and 304 stainless steel, which means it can be easily rolled, stamped and formed.

Can OCr17Ni12Mo2N stainless steel be welded?

Welding of OCr17Ni12Mo2N stainless steel is often considered a difficult task, however, with the right tools and technique, it can be accomplished with ease. Some of the key properties that make OCr17Ni12Mo2N stainless steel an ideal welding material are its high strength, corrosion resistance and weldability.

What is the corrosion resistance of OCr17Ni12Mo2N stainless steel?

OCr17Ni12Mo2N stainless steel is an austenitic stainless steel with high content of chromium and nitrogen. The high chromium and nitrogen content give the steel excellent corrosion resistance. The steel also has good mechanical properties and is easy to weld and form.

How about the manufacture and heat treatment of OCr17Ni12Mo2N stainless steel?

OCr17Ni12Mo2N stainless steel is an austenitic chromium-nickel alloy with low carbon content. It is widely used in occasions where the corrosion resistance of 304L stainless steel is insufficient. The addition of molybdenum improves the corrosion resistance of OCr17Ni12Mo2N stainless steel to pitting and crevice corrosion in chloride environment. The higher molybdenum content also gives OCr17Ni12Mo2N stainless steel better resistance to pitting and crevice corrosion in generally corrosive environments. OCr17Ni12Mo2N stainless steel can be solution annealed in the temperature range of 1010-1150 degrees, and then cooled rapidly. OCr17Ni12Mo2N stainless steel cannot be hardened by overheating.

What are the advantages and disadvantages of OCr17Ni12Mo2N stainless steel? 

While OCr17Ni12Mo2N stainless steel is primarily used for the production of fasteners and other small parts, it is occasionally used for larger projects. As with all grades of stainless steel, there are both advantages and disadvantages to using OCr17Ni12Mo2N.

advantage:

- OCr17Ni12Mo2N stainless steel is more corrosion resistant than other grades of stainless steel. This makes it ideal for applications where corrosion resistance is a critical concern.

-Although OCr17Ni12Mo2N stainless steel has high corrosion resistance, it is still relatively easy to process. This makes it ideal for applications requiring fabrication and welding.

shortcoming:

- OCr17Ni12Mo2N stainless steel is more expensive than other grades of stainless steel. This makes it a less cost-effective option for certain applications.

-Because of being more corrosion resistant, OCr17Ni12Mo2N stainless steel may require more frequent cleaning and maintenance than other grades of stainless steel.

What is the use of OCr17Ni12Mo2N stainless steel?

OCr17Ni12Mo2N stainless steel is a nitrogenated version of 316 stainless steel.
