motor shaft of stainness steel303.suitable for automatic lathes,
bolts and nuts.
303 stainless steel is austenitic respectively containing sulfur
and selenium free cutting stainless steel, used for the
requirements of easy cutting and high surface finish of the
303 stainless steel is austenitic stainless steel cutting wear
acid, to improve the performance of the steel in steel to not more
than 0.60% molybdenum, resistant to erosion.
303 stainless steel mechanical properties after annealing to
stress, tensile 515MPa, yield 205MPa, elongation rate of 40%.
stainless steel 303 standard hardness 90-100 HRC, 20-25 HRB, note:
HRB100 = HRC22.9.
The 303 is respectively containing sulfur and selenium free cutting
stainless steel, improve the cutting performance of the main
requirements for cutting and surface finish high.303 stainless
steel and high-temperature bonding properties. Most suitable for
automatic lathes, bolts and nuts.
