The molybdenum content increases corrosion resistance, improves resistance to pitting in chloride ion solutions, and increases strength at high temperatures.ģ16 stainless steel is particularly effective in acidic and corrosive environments. The 316 steel is an austenitic chrome-nickel stainless steel containing between two and three percent molybdenum. 316L is also a fantastic stainless steel for high temperature, high corrosion use, and is therefore popular for use in construction and offshore projects. However, 316L is a better choice for projects that require a lot of welding because 316L is more reliable than 316L in terms of welding maturity. They are both very powerful, corrosion resistant, and a good choice for high voltage situations. But although it has less carbon, the 316L is very similar to 316 in almost every way. This is easy to remember, as L stands for "low" as mentioned earlier. The differences between 316 and 316Lģ16 stainless steel contains more carbon than 316L. They are also both non-curable by heat treatment and can be easily shaped. Properties quoted below are guideline figuresonly nad should not be used for any design purposes.Welding seam Features shared by 316 and 316Līoth 316 and 316L are similar to 304, which is used in the food industry, among other things, but types 316 and 316L have better corrosion resistance and are stronger at high temperatures. Stainless steel work hardens rapidly, heavy positive feeds, sharp tooling, and a rigid set-up should be used. The use of chip breakers is advised since the chips can be stringy. Two important considerations in producing weld joints in the austenitic stainless steels are: Grade 304L is more resistant to carbide precipitation and can be heated into the above temperature range.Įxcellent welding properties post-weld annealing is not required when welding thin sections.Continuous use of 304 in the 800-1580☏ range is not recommended if subsequent aqueous corrosion resistance is important. Good oxidation resistance in intermittent service to 1600☏ and in continuous service to 1690☏.Grade 304L is preferred for use in environments sufficiently corrosive to cause intergranular corrosion of welds and heat-affected zones on susceptible alloys.At times, grade 304L may show a lower corrosion rate than the higher carbon Alloy 304 otherwise, the 304 and 304L may be considered to perform uniformly in most corrosive environments.Resistance to corrosion in oxidizing environments is a result of the 18 to 19% chromium that the 304 alloys contain.Resistance to moderately aggressive organic acids is a result of the 9 to 11% nickel that the 304 alloys contain.Woven or welded screens for mining, quarrying & water filtration.Chemical containers, including for transport.Automotive and aerospace structural use. Food processing equipment, particularly in beer brewing, milk processing, and winemaking.Nuts, bolts, screws, and other fasteners in the marine environment.
