SF-1S stainless steel corrosion resistant material

  • parameters

SF-1S stainless steel corrosion-resistant material is made of stainless steel material, sintered in the middle of corrosion-resistant alloy powder, and the surface is rolled with low-friction material mainly composed of polytetrafluoroethylene. It is resistant to oils, acids, alkalis, seawater and abrasion. It is most suitable for use in food and beverage machinery, chemical pumping valves with moderate acid-base flow, pharmaceutical machinery, printing and dyeing machinery, chemical machinery, and marine industry. This material is lead-free and meets the requirements of the EU ROHS Directive.
