Martensitic Stainless Steel 410S (S41008 / 1.4003 / SUS410S) Features: Mechanical properties: can be strengthened by heat treatment, moderate hardness (HRC 25-35), both wear resistance and certain toughness. Corrosion resistance: weaker than austenitic stainless steel, but performs well in mild environments (dry atmosphere, weak acid). Applications: General mechanical parts: shafts, pump parts, fasteners (scenes requiring medium strength and cost sensitivity). Automobile manufacturing: exhaust system brackets, brake disc edges (parts with low demand for high temperature oxidation resistance). Tools and tools: low-load tools, mold bushings (replacing high carbon steel to extend service life). Home appliance parts: washing machine inner drum support, oven internal bracket (areas not in direct contact with corrosive media). Limitations: Not suitable for high humidity, high chloride ion (such as coastal areas) or strong acid environments, and requires surface coating (such as galvanizing) protection. The heat treatment process has strict requirements, and improper treatment may lead to increased brittleness. Alternative options: For higher corrosion resistance requirements: 304 or 430 stainless steel can be selected; For higher strength requirements: 420 or 440C stainless steel can be selected. 🔍 Website: www.juyemetal.com 📞 Whatsapp：+86 13958321412 💌Email：[email protected]
