Stainless Steel

EN 10088

Stainless steel is a rolled chromium steel with very high corrosion resistance.

Steels that are resistant to corrosion and to heat, usually known as stainless steels, are composed of alloy elements like nickel, molybdenum, titanium, niobium, copper and sulphur, in addition to iron and to chrome.

Stainless steels are composed of at least 12% chrome. This basic stainlessness can be increased to produce various categories of stainless steel.

Ferritic steels

: ferromagnetic, > 16% chrome (AISI  430, 441)

Austenitic steels

: non magnetic, > 16% chrome, 8% nickel (AISI 304, 316), have greater resistance to corrosion.

Origoni Zanoletti sells coils, sheets and strips of series 300 and 400 steel and normally processes stainless steel on a painting line on one side or on both sides for primer applications to improve glues and polyurethane foams adhesion.

Surface finishes

The most common finishes are 2B (glossy, obtained by passing lightly through a rolling mill with Skinpass mirror cylinders), BA (mirrored), various glazing and brushing processed (Scotch Brite)

Main applications

AISI 304

: Construction, Plumbing, Furniture, Piping, Food Industry.

AISI 316

: Chemical industry, highly polluted environments.

AISI 430

: Household appliances, painted for outdoor use for industrial and residential construction with great resistance to corrosion.
