What are the marine stainless steel materials?

   

     304L low carbon stainless steel

  304L low carbon stainless steel is a general stainless steel material and a stainless steel with austenitic structure, which is widely used in the production of marine equipment requiring good comprehensive properties (corrosion resistance and formability).

  316L low carbon stainless steel

  316L low carbon stainless steel After 304L low carbon stainless steel, 316L low carbon stainless steel is the second most widely used austenitic stainless steel grade. Because the addition of molybdenum (Mo) metal element makes it obtain excellent corrosion resistance, it is often used in the food industry and surgical equipment. Compared with 304L low carbon stainless steel, 316L low carbon stainless steel has better resistance to chloride corrosion, so it is also called "marine stainless steel".

  2205 Duplex Stainless Steel

  2205 duplex stainless steel is a duplex stainless steel composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. Its yield strength is more than double that of 304L low carbon stainless steel and 316L low carbon stainless steel. This feature makes 2205 duplex stainless steel lighter than two low carbon stainless steels. It has high strength, good impact toughness and good overall and local stress corrosion resistance.
