Stainless steel is also called corrosion-resistant steel or CRES when the alloy type and grade are not detailed, particularly in the aviation industry. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments.

Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion and blocks corrosion from spreading into the metal's internal structure, and due to the similar size of the steel and oxide molecules they bond very strongly and remain attached to the surface.

Stainless steel perforated casing pipes are manufactured according to standard API 5CT and 5B, material includes: ASTM SS304/304L, SS316/316L, etc
