We stock stainless steel sheet and strip from .20 mm thickness to 3.00 mm in 301 temper rolled and 420 hardened and tempered. 301 is ideal for making small springs without the necessity for heat treatment. 420 is suitable for the manufacture of blades, cutlery etc. For general spring manufacture we recommend 301. 420 is included in our stock as along with spring steels it is widely used for blade manufacture, but unsuitable for springs. Type 301(1.4310) is an austenitic steel, it permits cold working to the ideal combination of mechanical properties desired for springs. Its unique combination of hardness and toughness makes for better forming quality in this Full Hard Temper plus increased fatigue life in the finished spring. 420 is a martensitic hardened and tempered steel ideal for flat springs, blades and cutting tools
