Stainless steel can be divided into five major families and over thirty categories. The grades depends on the type of element that has been introduced into the alloy. Knowing the different types of stainless steel and their uses is important.
304 stainless steel
300 Series stainless steel is the most widely used alloy, with type 304, in particular, being the most commonly used. 304 stainless steel is found in many products such as industrial kitchens, kitchen sinks, household appliances, architectural railings, etc. Due to the multiple qualities of the 304 grade, its production is equivalent to more than 50% of all stainless steels worldwide
316 stainless steel
Grade 316 stainless steel is very similar to 304. Its main difference is that 2% molybdenum has been added, thereby enhancing corrosion resistance in specific situations (e.g., saline environments).
430 stainless steel
430 stainless steel is one of the few stainless steels that is magnetic. The mechanical properties of this steel are lower than those of grade 300 steel with regard to the resistance of the welds to pressure and the resistance of the surface to corrosion.
