Industries & Applications

Type 301 stainless steel is an austenitic stainless steel capable of achieving high mechanical strength and ductility by cold working. This steel is not hardenable by heat treatment, is non-magnetic in the annealed condition and begins to become magnetized with cold working. Type 301 is preferred over 302 and 304 in the hardened condition because it achieves high elongation combined with high strength, which facilitates its fabrication and broadens its applications.

Springs, screws, bolts, springs, fasteners, clips, clamps, pins, computer parts, electrical connectors, contactors, variety of stamped parts.

Type 302 stainless steel is an austenitic stainless steel capable of achieving high mechanical strength and ductility by cold working. This steel is not hardenable by heat treatment, is non-magnetic in the annealed condition and begins to increase in magnetism with cold working.

Springs, screws, bolts, springs, fasteners, clips, clamps, pins, computer parts, electrical connectors, contactors, variety of stamped parts.

Type 304 is the most widely used of the austenitic stainless steels, it is non-magnetic in the annealed condition and becomes magnetic when cold work is applied. Type 304 is generally used in the annealed condition because of its good combination of corrosion resistance and formability. It is recommended whenever possible to change to type 301 if hardening is required because it does not harden easily.
