Increase its tensile strength at a temperature 15 ~ 80 ° C range is relatively uniform. More importantly: stainless steel screws with decreasing temperature, slowly reducing its impact toughness, there is no brittle transition temperature. So stainless steel at low temperatures to maintain sufficient ductility and toughness.
