General Information - About Stainless Steel Over   time,   corrosion   can   have   a   devastating   effect   on   carbon   steel.   By   taking   chromium,   in   amount   greater   than   11%   and   adding   it   to carbon steel we create a steel with improved corrosion resisting properties – Stainless Steel. The   chromium   content   of   the   steel   creates   the   formation   of   a   tough,   adherent,   invisible,   corrosion   resisting   chromium   oxide   film   on   the steel    surface.    The    stainless    steel    family    has    many    Grades    with    different    characteristics.    The    corrosion    resistance,    and    mechanical properties   as   well   as   other   useful   properties   is   enhanced   by   increasing   the   chromium   content   and   the   addition   of   other   alloying   elements such as nickel, titanium, molybdenum and nitrogen. Long Term Value When the total life cycle costs are considered, stainless steel is often the least expensive option. Low Maintenance Costs Stainless   steel   is   washable   using   a   dilute   solution   of   household   detergent   without   ammonia   or   chloride.   Surfaces   should   be   washed   with   a soft    sponge    and    clean    water.    Where    stainless    steel    is    used    under    conditions    such    as    fire    applications    compounded    with    harsh environmental    conditions,    corrosion    attacks    the    material    but    can    be    repaired    following    proper    techniques    such    as    chemical    or mechanical processes if the surface finishes permit this. NOTE:   Always   ensure   that   if   the   appliance   is   received   with,   typically   a   white   PVC   plastic   film   over   the   stainless   steel   to   protect   it,   is   properly removed.   Also   that   once   the   PVC   plastic   film   is   removed,   that   the   glue   residue   that   it   leaves   behind,   is   washed   off.   This   can   be   done   by carefully   washing   these   places   with   very   hot   soapy   water.   One   must   be   careful   not   to   burn   due   to   the   hot   water.   This   prevents   smells when operating the appliance and makes it less prone to chloride corrosion attack – more aggressive closer to coastal areas. Ease of Fabrication Modern   steel   manipulation   techniques   mean   that   stainless   steel   can   be   cut,   welded,   formed   and   fabricated.   Stainless   steel   is   not   difficult to fabricate, however different techniques need to be used. Corrosion Resistance Lower   alloy   grades   resist   corrosion   in   normal   atmospheric   and   potable   water   environment,   while   the   more   highly   alloyed   grades   can   resist corrosion   in   many   acids   and   alkaline   solutions,   and   some   chloride   bearing   environments.   With   the   range   of   grades   of   stainless   steel,   this   is not a problem, but you are advised to contact your supplier for more information. 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 tend to work harden with cold working. Hygiene Internationally   recognized   as   by   far   the   most   hygienic   surface   for   the   preparation   of   foods.   The   unique   surfaces   of   stainless   steel   have   no pores   or   cracks   to   harbour   dirt,   grime   or   bacteria.   This   cleans   ability   far   exceeds   other   surfaces   and   makes   it   the   first   choice   for   hygienic conditions, such as hospitals, kitchens, abattoirs and other food and beverage applications.
