Stainless steel is an alloy composed mainly of iron, carbon and chromium, which is widely used in various industries for its excellent corrosion resistance and beautiful surface. Here are some common stainless steel products and their characteristics:
Main types
1. Austenitic stainless steel: such as 304 and 316 stainless steel, with excellent corrosion resistance and formability, often used in kitchen utensils, medical devices and building materials.
2. Ferritic stainless steel: such as 430 stainless steel, with good corrosion resistance and magnetism, often used in automobiles and home appliances.
3. Martensitic stainless steel: such as 420 stainless steel, with high strength and hardness, but low corrosion resistance, often used in knives and turbine blades.
4. Duplex stainless steel: such as 2205 stainless steel, combines the advantages of austenitic and ferritic stainless steels, with high strength and excellent corrosion resistance.
5. Precipitation hardening stainless steel: such as 17-4 PH, provides high strength and corrosion resistance through heat treatment, and is often used in aerospace and chemical equipment.
Main characteristics
·Corrosion resistance: Stainless steel can resist oxidation and corrosion due to the passivation layer formed on the surface due to its chromium content.
·Strength and hardness: Different types of stainless steel have different strengths and hardnesses, suitable for various application scenarios.
·Weldability: Most stainless steels have good weldability, suitable for manufacturing complex structures and equipment.
·Aesthetics: Stainless steel has a high surface finish and is suitable for products that require an aesthetic appearance.
Application areas
·Architectural: For structural components, cladding and roofing.
·Automotive: For exhaust systems, fuel tanks and decorative parts.
·Medical: For surgical instruments, implants and equipment.
·Household appliances: For kitchen utensils, dishwashers and refrigerators
