316L stainless steel plate Chinese stainless steel

China Shandong Baote metal products Co., Ltd. specializes in producing steel pipe diameter: 6mm-1200mm!

316L is a brand of stainless steel, AISI 316L is the corresponding American brand and Sus 316L is the corresponding Japanese brand. China's unified digital code is s31603, the standard brand is 022cr17ni12mo2 (new standard), and the old brand is 00Cr17Ni14Mo2, which indicates that it mainly contains Cr, Ni and Mo, and the number indicates the approximate percentage. The national standard is GB / T 20878-2007 (current edition).

Various types of steel pipes and non standard steel pipes can be created by suppliers

Spot sales of steel pipes: bid winning steel pipes, American standard steel pipes, German standard steel pipes, British standard steel pipes, Japanese standard steel pipes and French steel pipes. We sincerely welcome friends from all walks of life to visit, investigate and negotiate business, and hand over the order to us, so that the purchasing customers can save worry and effort. Our steel pipes are exported to Germany, the United States, South Africa, the Middle East, India, South Korea, Pakistan, Iran and other parts of the world.

316L is widely used in the chemical industry because of its excellent corrosion resistance. 316L is also a derivative steel of 18-8 austenitic stainless steel, with 2 ~ 3% Mo added. On the basis of 316L, many steel grades are derived, such as 316Ti after adding a small amount of Ti, 316N after adding a small amount of N, and 317L after increasing the content of Ni and mo.

Most of the existing 316L on the market are produced according to American standards. In consideration of cost, steel mills generally limit the Ni content of products to the lower limit as far as possible. The American standard stipulates that the Ni content of 316L is 10 ~ 14%, and the Japanese standard stipulates that the Ni content of 316L is 12 ~ 15%. According to the minimum standard, there is a difference of 2% in Ni content between American Standard and Japanese standard, which is reflected in the price. Therefore, when purchasing 316L products, customers still need to see whether the products refer to ASTM or JIS standards.

Annual sales materials of Baote steel pipe: ASTM A53-B, A106A / B, St45-8, 10#, 20#, 35#, 45#, Q355 (ABCD) 20CrMo44, 4119, 4130, 4135, 4140, 4340, 20g, 40Mn2, 45Mn2, 27SiMn, 40MnB, 20mnvb, 20Cr, 40Cr, 35CrMo, 42CrMo, 12Cr1MoV, 38CrMoAl, 50CrV, 20CrMnSi, 30CrMnSi, 35CrMnSi, 20CrMnTi, 30crmnti, 40CrNiMoA, 15CrMoG 201, 202, 301, 304, 316, 321, 316L, 310S, etc

The two most commonly used stainless steels 304316 (or corresponding to 1.4308 and 1.4408 of German / European standard), the main difference between 316 and 304 in chemical composition is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance and is more corrosion resistant than 304 in high temperature environment. Therefore, in high temperature environment, engineers generally choose 316 parts. But the so-called thing is not absolute. In the environment of concentrated sulfuric, never use 316 at any high temperature Or it'll be a big deal. 

People who study mechanics have all studied threads. I still remember a dark solid lubricant that needs to be applied to prevent threads from biting under high temperature: molybdenum disulfide (MoS2), from which two conclusions can be drawn: first, Mo is indeed a high-temperature resistant material (do you know what crucible gold is melted in? Molybdenum crucible!). 2: Molybdenum easily reacts with high valence sulfur ions to form sulfide. Therefore, no stainless steel is super invincible and corrosion-resistant. In the final analysis, stainless steel is a piece of steel with more impurities (but these impurities are more corrosion-resistant than steel). If it is steel, it can react with other substances.

The company was founded in 2003. It abides by the contract and reputation. While continuously improving the competitiveness of customers through service, it has also won market praise for ourselves.
