Why do 316L stainless steel pipe fittings have better corrosion resistance

Why do 316L stainless steel pipe fittings have better corrosion resistance 316 stainless steel is a molybdenum-containing stainless steel. Due to the molybdenum in the steel, the overall performance of this steel is better than 310 and 304 stainless steel. Under high-temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 1. 316 stainless steel also has good chloride corrosion resistance, so it is usually used in marine environments. The carbon content of 316L stainless steel is 0.03, which can be used in applications where annealing cannot be performed after welding and corrosion resistance is required. 2. Corrosion resistance: The corrosion resistance is better than 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper. Moreover, 316 stainless steel is also resistant to corrosion in marine and corrosive industrial atmospheres. 3. Heat resistance: 316 stainless steel has good oxidation resistance in intermittent use below 1600 degrees and continuous use below 1700 degrees: 316 stainless steel should not be used continuously in the range of 800-1575 degrees, but it has good heat resistance when used continuously outside this temperature range. 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel and can be used in the above temperature range.
