Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper
and titanium. The alloy's chemical composition is designed to provide exceptional

STAINLESS STEELSTAINLESS STEEL
Character of Stainless Steel
TP304l(S30403)
Stainless steel 304L, the low carbon version of 304, does not require post-weld
annealing and so is extensively used in heavy gauge components (over about 6mm).
TP304(S30400)
Stainless steel 304 is a 300 Series Stainless Steel austenitic. It has a minimum of
18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is
defined as a Chromium-Nickel austenitic alloy.
It is used for a wide variety of home and commercial applications, this is one of the
most familiar and most frequently used alloys in the stainless steel family.
TP316(S31600)
Type 316 is a molybdenum-bearing grade. This addition gives the better overall
corrosion resistance properties than type 304 and higher creep strength at elevated
temperatures. Type 316 gives useful service at room temperature in sulphuric acid of
concentration of lower than 15% and higher than 85%. It also resists chloride attack
and is often selected for use in marine atmospheres.
TP 316L(S31603)
Type 316L stainless steel is a molybdenum bearing austenitic. It is more resistant to
general corrosion and pitting than conventional nickel chromium stainless steels
such as 302-304. It has higher creep resistance, excellent formability, rupture and
good tensile strength at high temperatures, good corrosion and pitting resistance.
