Do not use abrasive cleaners that will scratch the surface.
Depending on the surface finish of your stainless steel, abrasive cleaners can cause scratching. Duller finishes probably won’t show scratching as much as mirror or highly polished finishes. When in doubt, test in a hidden spot, and also work from the least risky type of cleaning, [...]

Annealing
The steel is heated to a temperature above or within the critical range, then cooled at a predetermined slow rate (usually in a furnace) to produce a coarse pearlite structure. This treatment is used to soften the steel for improved machinability; to improve or restore ductility for subsequent forming operations; or to eliminate the residual [...]

Stainless steel is defined as a steel alloy with a minimum of 11.5 wt% chromium content.Stainless steel does not stain, corrode or rust as easily as ordinary steel (it “stains less”), but it is not stain-proof. It is also called corrosion resistant steel when the alloy type and grade are not detailed, particularly in the [...]

Usage of stainless steel in Marine Environments
The metals most commonly used today in the construction of yachts, marine structures and fittings are stainless steel and aluminium. While aluminium is light, it has limited corrosion resistance in seawater and requires significant maintenance. Stainless steel, on the other hand, is recognised as the premium material [...]

Selection of stainless steel grades
Stainless steels have diverse properties which provide viable and cost-effective solutions to a vast range of applications. In practice, development of a hierarchy of required properties reduces the range to a manageable number of highly versatile materials, enabling users to choose the most appropriate grade for the particular application.
The family [...]
