301 is an austenitic stainless steel, widely used in it’s temper rolled condition for the manufacture of small springs, without the need for heat treatment. our 301 falls within GB ∕ T20878-2007, this grade is also known as 12Cr17Ni7
Stainless steel 301 has a good corrosion resistance due to a content of 17 % Chromium and 7 % Nickel. A high tensile strength is obtained by cold rolling. Compared to Alloy 1.4301 (AISI 304) a much higher tensile strength of more than 2000 N/mm²(HV610) can be reached. Because of this, 1.4310 is suitable for stainless feeler gauge stock, precision foils, stainless springs and parts of higher strength. This alloy is little magnetic and can not be held by magnetic tables of grinding machines.
