Product Description

The 301 stainless steel belt is a kind of metastable austenitic stainless steel with complete austenitic structure under the condition of sufficient solution.

In stainless steel, 301 is the most easily cold deformation strengthening steel grade, through the cold deformation processing can make the strength of steel, hardness, and retain enough plastic and toughness, together with the steel under the condition of the atmosphere with good rust resistance, but the poor corrosion resistance, reducing medium in acid and alkali salt chemical medium corrosion resistance is poorer, therefore is not recommended for corrosion harsh environment.


The 301 is mainly used in cold working condition for equipment parts that bear high loads and want to reduce the weight of the equipment and do not rust.

In addition, this steel is easy to produce work hardening when impacted by external forces and can absorb more impact energy, which will provide a more reliable safety guarantee for equipment and personnel.

The 301 is prone to work hardening during deformation and is used in places requiring higher strength
