Sometimes known as tinite is an extremely hard ceramic material often used as a coating on titanium alloys steel carbide and aluminium components to improve the substrate s surface properties.
Steel sheets coated with tin reaction.
Pretreated and painted cold rolled steel crs when scratched is particularly susceptible for red rust bleeding especially in acidic corrosive conditions 12 therefore steel is often galvanized to protect the steel.
Stainless steel and galvanized materials often are found together in the industry with applications such as galvanized fasteners stainless steel pressure vessels and roof and siding panels.
Additionally the substrate has been changed from steel to stainless steel benefitting from the corrosion resistance of stainless steel alloys.

The presence of two dissimilar metals in an assembly is not always a sign of trouble but it could be a problem.
Today terne coated metal is coated with 99 9 tin instead of hot dipping a more consistent galvanic deposition process is applied.
Tin coated sheet is used to make a wide variety of parts including deep drawn oil filter shells electronic shields and bakeware.
