Stainless steel (304 - 316 - 316L)
These steels are characterised by a stable austenitic structure at any temperature, therefore there is no increase in mechanical strength after heat treatment.
The corrosion resistance is certainly good for all and is regarded as being notable for the low carbon types (such as 316L), with stabilising elements, with molybdenum, which resist in highly aggressive environments and in the presence of solutions that develop chlorine ions, as a result they are widely used in the oil, chemical, food, textile industries, in parts for furnaces and equipment for ships.
