SS304 VS SS316 which is better ?


In the daily home environment, we often see the words 316 or 304 on some stainless steel screws, the heart will have doubts: “316 stainless steel screws and 304 which good?” May wish to carry on the professional analysis and evaluation from the comprehensive performance, the advantage of 316 stainless steel screw is more obvious.

First analysis of the composition, 316 stainless steel screw than 304 more than one element molybdenum Mo, improve the 316 stainless steel screw corrosion resistance, high temperature resistance, adaptation to the environment becomes more extensive. In different complex environments in the industry, 316 stainless steel screws and 304 stainless steel screws with the same specifications are used. After a period of operation, 304 stainless steel screws will appear some rust spots or deformation, and 316 stainless steel screws do not have any abnormalities.

Because the comprehensive performance of 316 stainless steel screws is more excellent, they are mainly used in food, industry and surgical equipment. In order to achieve more ideal corrosion resistance, in the process of producing 316 stainless steel screws, manufacturers will consider adding molybdenum metal, so that the structure of the whole wire has a certain change, to reach the standard corrosion resistance value. In the manufacture of some chemical containers, 316 stainless steel screws will be used, and the appearance will not change after wind and rain. After witnessing different industries, 316 stainless steel screws have become one of the main hardware accessories of Marine steel.

Stainless steel is various and refined, that 316 stainless steel screws belong to austenitic stainless steel material, with the help of Mo element, high temperature resistance reached 1200-1300 degrees, 304 is an American brand of ordinary austenitic stainless steel. There are great differences in corrosion resistance, oxidation resistance, high and low temperature resistance and tensile strength. If the economic conditions allow, or use 316 stainless steel screws will be more ideal.
