![]() ![]() This is because a protective layer of chromium oxide cannot be formed due to lack of oxygen.Įspecially in small valves, the possibility of deposits on the valve plate is very small, so pitting corrosion rarely occurs. Pitting corrosion is a phenomenon mainly caused by deposit corrosion on the surface of stainless steel. Due to the worldwide shortage of molybdenum and the higher nickel content in 316 stainless steel, the price of 316 stainless steel is more expensive than 304 stainless steel. In addition, these additional molybdenum can also reduce the corrosion of certain hot organic acids.ģ16 stainless steel has almost become a standard material in the food and beverage industry. An additional 2-3% molybdenum can reduce this sensitivity, and thus 316 was born. Under certain circumstances, this material is more sensitive to Pitting Corrosion. The stainless steel originally developed is 304. Generally speaking, 304 stainless steel and 316 stainless steel have little difference in chemical corrosion resistance, but they are different under certain specific media. And 316 stainless steel is also resistant to corrosion by the ocean and corrosive industrial atmosphere. The corrosion resistance of 316 stainless steel is better than that of 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper. 316L stainless steel has a maximum carbon content of 0.03, which can be used in applications that cannot be annealed after welding and require maximum corrosion resistance. 316 stainless steel also has good chloride corrosion properties, so it is usually used in marine environments. 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. Due to the molybdenum in steel, the overall performance of this steel is better than 310 and 304 stainless steel. The molybdenum content in 316L stainless steel is slightly higher than that in 316 stainless steel. Scope of application: Products with special requirements for anti-grain boundary corrosion.ģ16 and 316L stainless steels are stainless steels containing molybdenum. Performance introduction: As a low-carbon series of 316 steel, in addition to the same characteristics as 316 steel, it has excellent grain boundary corrosion resistance. Scope of application: equipment used in seawater, chemical, dye, paper, oxalic acid, fertilizer and other production equipment photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts. It can be used under harsh conditions it has excellent work hardening (non-magnetic). Performance introduction: Due to the addition of molybdenum, 316 stainless steel has excellent corrosion resistance, atmospheric corrosion resistance and high temperature strength. Then what are the differences between 316 and 316L stainless steel? Check out the following article and you will get the answer. ![]()
