317L Stainless Steel Sheet Seawater Resistance For Boats And Ships
Product Description
317L (UNS s31726) alloy is an austenitic stainless steel based on molybdenum. Compared with conventional chromium nickel austenitic stainless steel such as 304 alloy, it has stronger chemical corrosion resistance. In addition, compared with conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance. It is a low carbon grade or l grade, which has anti sensitization properties during welding and heat treatment.
Compared with 316L, 317L steel has good seawater resistance and SCC resistance. It is used for boats and ships,chemical products and other chemical equipment requiring high corrosion resistance.
performance
Alloy 317L and 317LMN stainless steels are more resistant to atmospheric and other mild corrosion than conventional chromium nickel stainless steels. Generally speaking, the environment without corrosiveness to 18Cr-8Ni steel will not cause corrosion to alloys containing molybdenum
Alloy 317LMN and 317L stainless steel can resist the corrosion of sulfuric acid solution better than conventional chromium nickel stainless steel. The corrosion resistance of the alloy increases with the increase of the composition of gold and molybdenum. These alloys can withstand sulfuric acid at concentrations up to 5% in environments up to 120 ° f (49 ° C). These alloys have excellent corrosion resistance at temperatures below 100 ° f (38 ° C) and can resist the corrosion of higher concentration solutions.
Oxidation resistance of 317L stainless steel
Chromium nickel molybdenum steels have excellent oxidation resistance, and in the ordinary atmosphere, when the temperature is not higher than 1600-1650 ° f (871-899 ° C), the scale formation rate is low.
Sclerosis
These grades shall not be hardened by heat treatment.
