2.Introduction
2Stainless steel grade 301 is usually supplied in the form of strips and wires, with a tensile strength of up to 1800 Mpa, to produce tempers ranging from 1/16 Hard to Full Hard. By subjecting grade 301 to controlled analysis it is capable of retaining sufficient ductility even in ½ hard conditions. This form of grade 301 may be used in aircraft, rail car components and architectural structures. Tempers of this grade, ranging from ¾ to full hard, may be used in applications requiring high wear resistance and spring features with simple form designs.
