TEDDI STEEL
1 / 5
Stainless steel plate is an alloy material made from iron with the addition of chromium, nickel and other elements. According to different compositions and uses, stainless steel sheet can be divided into many different types.
1. Chromium Stainless Steel PlateContains at least 10.5% chromium, which forms a dense chromium oxide film for corrosion prevention. Widely used in chemical, petroleum, and pharmaceutical fields due to high temperature and corrosion resistance.
2. Nickel Stainless Steel PlateFeatures high nickel content to improve corrosion resistance and toughness. Commonly used in chemical and marine equipment manufacturing.
3. Titanium Stainless Steel PlateContains titanium to enhance strength, wear resistance, and high temperature performance. Widely used in aerospace and shipbuilding.
4. Aluminium Alloy Stainless Steel PlateIncorporates aluminium to improve strength and wear resistance. Commonly used in automotive manufacturing and construction.
5. Titanium Composite Stainless Steel PlateA composite material combining the corrosion resistance of stainless steel with the strength of titanium metal, offering superior durability for shipbuilding and chemical equipment.
