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
This is the most cost effective grade of steel. So the 301 Stainless Steel wire Price is lower compared to other grades of stainless steels and all metallic products in general. There are different versions of the material with low carbon and high carbon content. The low carbon version, 301 wires are very good for welding applications as they have less carbide precipitation and less localized corrosion.
301 is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc. Compared with 304 steel, the content of Cr and Ni is less, the tensile strength and hardness are increased during cold working, and it is non-magnetic, but it is magnetic after cold working. Uses: trains, aircraft, conveyor wires, vehicles, bolts, springs, screens.
