In the present times, the 304 and 316 stainless steel have been the two most popular kinds of materials specifically used for manufacturing of Sanitary valves. It would be pertinent to mention here that for normal customers, the ones who were not familiar with the sanitary valve materials, both the 304 and 316 steel have been simply different in their specific numbers.
However, the major difference would be relatively huge between them. Let us go through further in order to understand and gain knowledge on the kind of sanitary valve material to be chosen for your specific needs.
Understanding 304 and 316 stainless steel
It would not be wrong to suggest that the stainless steel products have been known to comprise of the mixture of several kinds of elements inclusive of nickel, chromium, manganese, and carbon. It would be accounting for why the 3014 stainless steel along with the 316 stainless steel has similar chemical composition. They have been deemed to be similar in their appearance as well. Despite the 304 stainless steel and the 316 stainless steel having similar composition, the 304 stainless steel would be similar only when coupled with the other element, called as Molybdenum.
The molybdenum would further increase the resistance of the corrosion of the material. It would be made ideal for a majority of acidic environments. Therefore, even though the 304 steel would win for the wide applicable rages, in specific scenarios, inclusive of the acidic material, highly concentrated saline environments, or industrial solvents, which would be causing corrosion and failure of the 304 stainless steel, the 316 stainless steel would be preferred. It would not be wrong to suggest that the inclusion of molybdenum in 316 steel has been the major reason for its exorbitant price to that of 304 stainless steel. On an average, the 316 stainless steel would cost nearly 20% to 30% more than the 304 stainless steel.
Whether 316 stainless steel is worth additional money
You may ponder upon the question whether 316 stainless steel has been worth the additional cost over the grade 304 steel. You should rest assured that every person has his or her own opinion. However, it would still be dependent on what and where you would be processing. In case you were having an application with decently powerful corrosives or looking forward to relying on chlorides, you should rest assured that you would be paying a premium for grade 316 stainless steel would be worth your time, money, and efforts.
