AUSTENITIC STAINLESS STEEL

  Is called the 300 series.

  It is basic make up is 18% chromium and 8% nickel

 Good to excellent corrosion resistance Good weldability and formability

 Good creep resistance

 Nonma!netic

 "he trucks use the stainless steel to make a boxes for

transport specific material# because$"he ustenitic &teel boasts superb hy!iene properties and is

!ood at workin! in both low and hi!h temperatures.

MARTENSITIC STAINLESS STEEL

  It has a carbon content which is hi!her than most other

stainless steels between 0.1 and 1.'%# also it has 18%

chromium.

  It is able to resist corrosion brou!ht about by en+ironmental

factors# it is still somewhat less durable than austenitic steel.

  "he most common uses for this type of stainless steel are

the manufacture of thin!s such as$

FERRITIC STAINLESS STEEL Is called the -00 series.

 It has carbon le+els of 10.% and '/% chromium

 Good corrosion resistance

 Good weldability and tou!hness

 "he fact that it is +ery hi!hly resistant to corrosion meansthat it can safely be used in sea water# and the fact that it is

!enerally actually less durable than austenitic steel.

  It is also useful when makin! thin!s such as$

DUPLEX STAINLESS STEEL

 "he two types of steel are combined in e2ual measure andthe resultin! steel contains a hi!her le+el of chromium and

an amount of nickel is lower.
