Is there any difference between 304 and 316 stainless steel tubes?
[1] Brand difference.
304:06Cr19Ni10, 304L: 00Cr19Ni10;
316:0Cr17Ni12MO2, 316L: 00Cr17Ni14Mo2.
[2] Composition differences.
[3] Corrosion resistance difference. In general, 304 stainless steel and 316 stainless steel both in the chemical corrosion resistance performance difference is not big, but in some specific medium. Some of their relationships can be clearly seen in the picture of "relationship between 304 and other stainless steel" shared before. When 304 stainless steel was initially developed, this material was more sensitive to spot corrosion under certain circumstances. To reduce these sensitivities an additional 2-3% of molybdenum was added, resulting in 316 stainless steel. And this extra molybdenum can also reduce the corrosion of certain thermal organic acids. In various types of water quality (distilled water, drinking water, river water, boiler water, etc.), 304 stainless steel and 316 stainless steel corrosion resistance is almost the same, but when the content of chloride ions in the medium is very high, 316 stainless steel is more suitable, specific case specific analysis.
[4] Price difference. Due to the worldwide shortage of molybdenum and the higher nickel content in 316 stainless steel, 316 stainless steel is more expensive than 304. [5] Low carbon type. The corrosion resistance of austenitic stainless steel comes from the protective layer of chromium oxide formed on the metal surface. When the material temperature is heated to 450 degrees - 900 degrees, the structure changes, will form chromium carbide along the crystal edge and can not form chromium oxide protective layer, thus reducing the corrosion resistance, this is also known as "intergranular corrosion". The result is 304L and 316L, which reduce intergranular corrosion due to their low carbon content. In particular, higher intergranular corrosion sensitivity does not mean that non-low carbon content is more susceptible to corrosion, and this sensitivity is also higher in a high chlorine environment.
