Red wine label how choose 2019 stainless steel.
17304 stainless steel is according to the United States ASTM standards to produce a brand of stainless steel.
304 0 cr19ni9 (equivalent to our country
304 19% chromium and nickel 9%.
304 is a kind of common stainless steel, it is widely used to produce good comprehensive performance (
Corrosion resistance and formability)
Equipment and parts.
316 l steel is the low C series of 316 steel grade, besides and 316 steel have the same characteristics, its corrosion resistance is better.
Stainless steel is molybdenum stainless steel 316 and 317.
Molybdenum content of 317 stainless steel was a little bit clever than 316 stainless steel.
Because of molybdenum in steel, the steel grade overall performance is better than that of 310 and 304 stainless steel, high temperature conditions, when the concentration of sulfuric acid is less than 15% and higher than 85%, the 316 stainless steel has a wide range of USES.
316 stainless steel also has good performance of chloride erosion, so often used in Marine environment.
The biggest carbon 0 316 l stainless steel.
03 and can be used for welding cannot be after annealing and the purpose of the maximum corrosion resistance.
Corrosion resistance is better than 304 stainless steel, in the process of pulp and paper production has good corrosion resistance performance.
Ocean and erosion resistance and 316 stainless steel industrial atmosphere.
316 stainless steel has good welding performance.
Can use all the standard welding method to weld.
When welding, can according to the purpose, 316 or 309 l, 316 cb and cb filler rod or electrode of stainless steel welding.
In order to obtain the best corrosion resistance, 316 stainless steel welding section of annealing treatment after welding is required.
If you use 316 l stainless steel, do not need to undertake annealing treatment after welding.
200 series stainless steel is during the second world war, as a substitute for 300 series stainless steel developed first in the United States.
At the time, because of the war, as the strategic materials of nickel were strictly controlled in various countries concerned, the serious shortage of supply of nickel.
In order to solve the shortage of nickel supply situation, the production and supply of stainless steel, the United States developed in the new steel grade manganese generation of nickel austenitic stainless steel series.
After the end of world war ii, the United States nickel supply conditions gradually improved, therefore, 300 series stainless steel production is no longer the restriction of the raw materials nervous, so 200 series haven't get bigger development.
Several had Indian people involved in the development of 200 series stainless steel, after return to India, from India is a manganese resources are relatively abundant, lack of nickel resources, according to the conditions of the development in the United States 200 series steel varieties of stainless steel back to India.
The destruction of 200 series steel under acid condition speed is about 10-304 stainless steel
