Stainless steel plate is an alloy material made from iron with the addition of chromium, nickel and other elements. It is categorized into various types based on composition:
🔹 Chromium Stainless Steel: Contains at least 10.5% chromium. Excellent corrosion resistance. Widely used in chemical and petroleum fields.
🔹 Nickel Stainless Steel: High nickel content improves oxidation resistance and toughness. Ideal for marine and chemical equipment.
🔹 Titanium Stainless Steel: Enhanced strength and wear resistance for aerospace and shipbuilding.
🔹 Aluminium Alloy Stainless Steel: Improved high-temperature resistance for automotive and construction.
🔹 Titanium Composite: Combines stainless steel's corrosion resistance with titanium's strength.
