Stainless steel bar is divided into a lot of kinds, and stainless steel bars are made of different materials have different performance and function. 316 and 304 stainless steel bar containing different content of chemical element, there are some different performance difference. From the using range and value, 316 stainless steel is better than 304 stainless steel bar, it took a lot of advantages.
Before introduce the difference of two kinds of stainless steel with good or bad, in order to help the many who are buyers, very good to distinguish the two kinds of materials. First to explain how to use stainless steel testing potion, to two kinds of stainless steel bar, fundamental difference. Actually this potion examination, mainly for stainless steel and nickel element in molybdenum elements content in different, effectively. In the use of liquid for two kinds of stainless steel material, testing, can be different by chromogenic reaction, contrast numerical table, investigate what kind of stainless steel bars.
Compared two kinds of stainless steel bar, due to the content of containing molybdenum elements in 316, more than 304. So in the ocean and chemical industrial environment, the corrosion resistance of 316, is better than 304 stainless steel. 316 stainless steel and also can according to adjust the structure of components, create a more suitable for the material in the industrial building. So-called 304 with 316 stainless steel bar, it is according to the ASTM standard to produce a brand. In different countries and regions, has a different name. 304 contains 19% chromium and 9% nickel element, while 316 containing chromium, nickel element is as high as 12% and 17% and 2% molybdenum elements.
Because contain a kind of elements, with 316 stainless steel with more performance. Such as have better between fine corrosion resistance ability, the ability to resist oxidation corrosion, and reduce the warm tendencies. In addition, also have good resistance to chloride corrosion performance, the phrase sanitary requirements higher. Although both strength and hardness, but the performance of the 316 stainless steel bar, if only there were some slightly.
