Trillion Connaught Ltd. 316L is a stainless steel grades containing mainly Cr, Ni, Mo numerals probably contains the percentage (not accurate, just probably), 316L This material corresponding label, sus 316L is a corresponding reference numeral. The China standard grades for 022Cr17Ni12Mo2 old grades (new standard) 00Cr17Ni14Mo2 chemical composition of carbon C: ≤ 0.030 silicon Si: ≤ 1.00 Manganese Mn: ≤ 2.00 316l trillion promise Hotline: 010-84329660 http://bjzhaonuo.com. the cn / sulfur S: ≤ 0.030 P: ≤ 0.035 Chromium Cr: 16.00 ~~ 18.00 Ni-Ni: 12.00 16.00 Mo Mo: 2.00 to 3.00 corrosion resistant 316L because of their excellent corrosion resistance in the chemical industry has a wide range of applications, 316L also belong derivative 18-8 type austenitic stainless steel grades, add 2 to 3% of Mo element. Also derived on the basis of 316L many kinds of steel, and to add small amount of Ti derived 316Ti, after adding a small amount of N, for instance derived from a 316N, an increase of Ni and Mo content derived 317L. 316L majority of existing on the market is produced in accordance with the American standard. For cost reasons, the steel mills generally to the Ni content of the product down as much as possible limit rely on. American Standard provisions 316L Ni content of 10 to 14%, the Japanese standard provisions 316L Ni content of 12 to 15%. According to the minimum standard, American standard, and the standard Ni content 2% of the difference reflects the enormous price, so customers need to see or buy 316L products, products with reference to ASTM or JIS standard. 316L Mo content makes the steel has excellent resistance to pitting, containing halogen Cl-ion environment can be safely used. As the the 316L main application of its chemical properties, steel mills demanding customers on the surface of the 316L surface inspection requirements slightly lower (relative to 304), to strengthen the the surface inspection efforts. Mechanical properties of tensile strength σb (MPa): ≥ 480 conditions yield strength σ0.2 (MPa): ≥ 177 Elongation δ5 (%): ≥ 40 Reduction of area ψ (%): ≥ 60 Hardness: ≤ Less than 187HB; ≤ 90HRB; ≤ 200HV Hardness ≤ 187HB ≤ 90HRB ≤ 200HV density: 7.98g/cm3; ratio of specific heats (20 ℃): 0.502J / (g * K) thermal conductivity (W / (m * K)) 100 ° C 300 ° C 500 ℃ 15.1 18.4 20.9 1010 ~ 1150 ℃ fast-cooling heat treatment solid solution. Microstructure organization for the austenitic type. Differences and identify 316L stainless steel and 304L stainless steel are the two most commonly used stainless steel 304, 316 (or corresponding to the German / European standard 1.4308,1.4408), 316 and 304 in the chemical composition of the most important distinction is the 316 containing Mo, and generally accepted 316, the corrosion resistance is better than 304 more resistant to corrosion in high temperature environments. Therefore, under high temperature environment, the engineer will generally choose to 316 parts of the material. But things are no absolutes, concentrated sulfuric acid environment, no matter how high the temperature also do not use 316! Otherwise, this may make a big. Who studied mechanical engineering and learned thread, remember that in order to prevent thread killed in a high-temperature case, the need to smear a dark solid lubricants: molybdenum disulfide (MoS2), derived from it 2:00 The conclusion is not: [1] Moisturizer is indeed a high temperature material (know the gold what crucible melting? molybdenum crucible!). [2]: molybdenum easily and High sulfur ion reaction to generate the sulfide. So there is no any kind of stainless steel is invincible super corrosion resistance. After all, stainless steel is an impurity (although these impurities than steel is more resistant to corrosion ^ ^) more steel, steel and other substances reaction.
