SUS410 Hex Flange Head Self Drilling Tapping Screw ST5.5-24*25 Corrosion Resistance Coating
TEK Stainless Steel 410 Series Products. products through special heat treatment, screw surface hardness up to more than HV750, core hardness between HV350 - HV450, whether it is surface hardness or core hardness are more than carbon steel screws, and its reasonable hardness ladder from the surface to the core to ensure the ideal combination of strength and toughness. SUS410 is martensitic stainless steel, its molding performance is good, can be heat treated; With high hardness, high strength, high temperature resistance, suitable for outdoor rain environment and corrosive environment; Although there will be red rust, but its corrosion rate is 0.01mm/ year, only 1/100 of ordinary carbon steel, even if the surface of the red rust, as long as gently wipe or polish, the surface will restore the inherent metallic luster.
