Why would someone need 302 stainless steel wall plates versus regular stainless steel wallplates? What is the difference?
302 Stainless steel has a greater corrosion resistance than regular stainless steel. It is also a non-magnetic metal and is used in a variety of commercial and industrial applications and anywhere food or beverages are served or sanitation is a concern. It is reputable for its good mechanical properties and in some places required by law to pass inspections. Spec grade stainless steel switch cover plates are the professional choice for government offices, utilities, and other facilities that must meet federal fire and safety requirements.

What direction is the brushing on 302 stainless steel wall plates?
One and two gang plates are vertically grained; three gang plates and larger have a horizontal grain. Satin brush finishes help hide fingerprints.

What color are 302 stainless steel wall plates? Are they the same color as regular 430 stainless steel?
Stainless steel color and finish is in between satin nickel and satin chrome finishes. 302 Stainless steel plates are a slightly warmer silvery-gray color than 430 stainless steel wall plates. Good match with brushed nickel finish faucets and fixtures.

What is the metal composition of 302 stainless steel?
These type 302 stainless steel (US Bureau Standards Symbol #32D) are made up of iron, 18% chrome and 8% nickel. Meets all UL standards.

Can I incorporate 302 stainless steel cover plates in my Nautical themed bedroom?
Definitely. 302 stainless steel wall switchplates can be used in a variety of decorating designs including, but not limited to, Contemporary, Scandinavian and Modern styles.

Yes, our 302 stainless steel collection is meant to be used in various commercial spaces such as warehouses, studios and gyms.

Types of Stainless Steels

There are three main types of stainless steel determined by their microstructure or predominant crystal phase: Austenitic, Ferritic and Martensitic. Austenitic steels have face centered cubic crystals or "austenite" as their main phase and include type 302 and type 304 stainless steel. Ferretic steels have body centered cubic crystals or "ferrite" as their main phase and include type 430. Martensitic steels are low carbon steels with a type 410 composition.

302 Stainless Steel Corrosion Resistance and Hardness

The common name for 302 stainless is Chromium-Nickel steel. Type 302 stainless steel has the same corrosion resistance as 304 stainless steel but with slightly higher strength due to additional carbon. It is commonly used in wire and strip form. When the alloy type and grade are not specified, stainless steel is called corrosion-resistant steel or CRES.

302 Stainless Steel Composition and Properties

Adding a minimum of 12% chromium to the steel makes it resist rust than other types of steel. Chromium in the steel combines with atmospheric oxygen to form a thin, invisible layer of chrome-containing oxide, called the passive film. Stainless steel does not stain, rust or corrode as easily as ordinary steel, in other words it stains less, however it is not stain-proof.

Type 302 stainless steel has a composition of iron, 18% chromium, and 8% nickel and is a slightly higher carbon form of type 304 stainless. Austenitic steels such as type 302 or type 304 can not hardened by heat treatment. Type 304 surgical stainless steel contains iron, 18-20% chromium and 8-10% nickel.

Ferritic steels such as type 430 stainless steel have a composition of 17% chromium. Ferritic steel is less ductile than austenitic steel and cannot be hardened by heat treatment. Martensitic steels are composed of iron, 12% chromium, and 0.12% carbon. They can be tempered and greatly hardened, but this reduces its toughness and makes it brittle. Few steels are fully hardened for this reason.
