Stainless steel pipe fittings are widely used in various industrial fields and life scenes. Their main materials and uses are as follows:
1. Main materials
1) 304 stainless steel:
Composition: Contains 18% chromium and 8% nickel.
Features: Good corrosion resistance, strong toughness, easy processing and welding.
Use: Suitable for food processing equipment, chemical equipment, medical equipment, architectural decoration, etc.
2) 316 stainless steel:
Composition: 2-3% molybdenum is added on the basis of 304.
Features: Excellent resistance to chloride ion corrosion, more resistant to high temperature and high corrosion environment.
Use: Widely used in marine environment equipment, chemical equipment, medical equipment, pharmaceutical equipment, etc.
3) 201 stainless steel:
Composition: Contains higher manganese and nitrogen, lower chromium and nickel content.
Features: Low cost, slightly worse corrosion resistance than 304, but good mechanical properties.
Use: Suitable for low-requirement decorative materials, household appliances, kitchen utensils, etc.
4) 321 stainless steel:
Composition: Titanium is added on the basis of 304.
Features: Good high temperature resistance and excellent resistance to intergranular corrosion.
Application: Suitable for high temperature environments such as aviation, exhaust systems, boilers, etc.
5) 430 stainless steel:
Composition: Contains high chromium but no nickel.
Features: Good corrosion resistance and formability, low cost.
Application: Suitable for interior decoration, home appliance parts, automotive decoration, etc.
