Marine Ship Stainless Steel Piping System

Three main marine stainless steels

304L low carbon stainless steel

304L low carbon stainless steel is a universal stainless steel material, and it is also a stainless steel with austenitic structure. It is widely used in the manufacture of marine equipment that requires good comprehensive properties (corrosion resistance and formability).

316L low carbon stainless steel

316L low carbon stainless steel is the second most widely used austenitic stainless steel after 304L low carbon stainless steel. Because the addition of molybdenum (Mo) metal element makes it obtain excellent corrosion resistance, it is often used in the food industry and surgery. 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. The weight is a bit lighter than the two low carbon stainless steels. It has high strength, good impact toughness and good overall and local stress corrosion resistance.
