unlike aluminium copper and gold stainless steel is not a metal it is an alloy, we do not find it in the periodic table.
stainless steel also known as inox steel as it is inoxydable.stainless steel is alloy of iron and corbon and cromium.
cromium forms a passive film to prevent corrosion.
the composition basically have
corbon 0.1 to 2.1 and cromium upto 10 to 11 percent by weight rest is iron.With superior durability, corrosion resistance, and dimensional stability, many of alloys are perfectly suited for utilization in marine and other industries.These are the few different kinds of stainless steel alloys Austenitic,Duplex, Ferritic,Martensitic,Precipitation Hardening,Superaustenitic and Superferritic
The grade of stainless mainly used in marine industry are
A1which is 303 grade A2 grade 304 and A4 grade316
the composition of these steel consists of
corbon , manganeese, phosporous, sulfer, cromium, molybdenum and nickel .
titanium phospate also alloyed with stainless steel which is widely used in aviation and marine industry
