|General Knowledge on stainless steel|
Grade SS 304 and Grade SS 316 are the austenitic stainless steel, the difference is 316 to pay more 2% molybdenum. 316 Such corrosion resistance, particularly resistance to chloride corrosion better than the 304. The price is about 20% more expensive. 304, 316, etc. are US Steel said the law No.
304 corresponds to domestic grades 0Cr18Ni9, is a versatile stainless steel, stainless steel is the most common, it is widely used to produce good overall performance requirements (corrosion resistance and formability) of equipment and parts, such as food equipment, general chemical equipment. 304 has excellent cold working and forming properties. Processing can produce plates, tubes, wire, tape, type a variety of products for the manufacture of cold heading, deep drawing, deep drawing molded parts. Welding in general, may be the usual welding methods of welding, brazing are not required before and after heat treatment. But 304 is also inadequate in performance: after welding sensitive to intergranular corrosion of steel large cross-sectional dimensions; CL- containing water (including wet atmosphere) is very sensitive to stress corrosion; low mechanical strength, machinability poor and so on.
F-304F represents sulfur content higher than the 304 or so almost doubled in about 0.1, more better in the processing process, followed by the words of rust resistance and the lack of a little more than 304 up a little!
304L corresponding domestic brands 00Cr18Ni11, lower carbon 304 stainless steel variant, the need for welding applications. Lower carbon content makes it close to the weld heat affected zone to minimize carbide precipitation, and carbide precipitation may lead to intergranular corrosion of stainless steel in some environments (welding erosion).
316 corresponding domestic brands 0Cr17Ni12Mo2, low-carbon stainless steel, welding performance is better than 304, and because the stainless steel containing molybdenum, which in the marine environment and the chemical industry point of corrosion resistance substantially better than the 304 stainless steel. High temperature conditions, when the concentration of sulfuric acid is less than 15% and above 85%, 316 stainless steel with a wide range of uses. 316 stainless steel also has a good corrosion performance and chlorides. Among them, 316 stainless steel variant include carbon steel 316L, 316N nitrogen and high strength stainless steel combined with higher sulfur content cutting stainless steel 316F.
Ultra-low carbon stainless steel 316L, the maximum carbon content of 0.03, can not be annealed for maximum corrosion resistance and require welding applications. Its corrosion resistance than 304 stainless steel, with good resistance in pulp and paper production process corrosion.
316 and 316L heat better, do use heat-resistant steel, 304 no. In the intermittent use of 1600 degrees and 1700 degrees continuous use in the following, the 316 stainless steel has good resistance to oxidation. In the range of 800-1575 degrees, it is best not to continuous operation, but continuous use 316 stainless steel outside the temperature range, the stainless steel has good heat resistance. Resistant 316L stainless steel carbide precipitation performance better than the 316 stainless steel, available in the above temperature range.
