Info on Stainless Steel

Stainless Steel is essentially a low carbon steel to which chromium has been added. It is this addition of chromium, in amounts greater than 12%, that gives the steel its unique 'stainless', corrosion resisting properties.

The chromium content of the steel allows the formation of a tough, adherent, invisible, corrosion resisting chromium oxide film on the steel surface. If damaged mechanically or chemically this film is self healing, provided that oxygen, even in very small amounts, is present. The corrosion resistance, as well as other useful properties of the steel is enhanced by increased chromium content and the addition of other elements such as molybdenum, nickel and nitrogen.

Benefits of Stainless Steel

Long Term Value
When the total life cycle costs are considered, stainless steel is often the least expensive option

Low Maintenance Costs
Stainless Steel normally only requires a periodic wash using a dilute solution of household detergent and water. Surfaces should be washed with a soft sponge and water.

Ease of Fabrication
Modern steel manipulation techniques mean that stainless steels can be cut, welded, formed and fabricated as readily as traditional steels and other materials.

Corrosion Resistance
Lower alloy grades resist corrosion in normal atmospheric and potable water environments, while the more highly alloyed grades can resist corrosion in many acids and alkaline solutions, and some chloride bearing environments, properties which are widely in process plants.

Strength
The mechanical properties of stainless steels allow thinner sections to be used than with other materials, thus reducing weight without compromising strength. Austenitic grades work harden with cold working and duplex steels allow for reduced thicknesses over traditional grades. Substantial cost savings therefore result as well as increased competitiveness with alternative materials.

Hygiene
Internationally recognised as by far the most hygienic surface for the preparation of foods. The unique surface of stainless steel has no pores or cracks to habour dirt, grime or bacteria. This cleansability far exceeds other surfaces makes it the first choice for strict hygienic conditions, such as hospitals, commercial kitchens, abattoirs and other food and beverage processing plants.

Aesthetic Appearance
The bright, easily maintained surface of stainless steel provides an attractive and contemporary appearance, ideal for a wide and growing range of applications
