DESCRIPTION
304 stainless is a low carbon (0.08% max) version
of basic 18-8 also known as 302. Type 302 has 18%
chromium and 8% nickel. Type 304 has slightly lower
strength than 302 due to its lower carbon content.
Type 304 finds extensive use in welding applications
because the low carbon permits some exposure in
the
carbide precipitation range of 800 0 F - 1500 OF
without the need for post-annealing operations.
However, the severity of corrosive environments
may necessitate annealing after welding or the use
of 304L. Type 304L has a carbon content of 0.03%
or less. This alloy can be used in the as-welded
condition without becoming susceptible to intergranular
corrosion.
DESIGN
FEATURES
Oxidation resistance up to 1650 0 F for
continuous service and up to 1 1500 deg.F where
cyclic heating is involved.
General purpose corrosion resistance.
Non-hardenable except by cold working.
Non-magnetic except when cold worked.
May be susceptible to chloride stress corrosion
cracking.
Used where field working is employed.
