Chemical and Pharmaceutical market
A wide range of service environments
are found in the chemical industry ranging from water to strong
acids or bases or a multitude of organic compounds at temperatures
ambient to 2300 º F (1260 ºC). Stainless steels are used
for a large percentage of these applications. In many inorganic
and organic chemical processes nickel alloys are used for the more
conditions where general corrosion, pitting or SCC can be present.
Nickel base alloys are often used in high temperature applications
above 1000ºF when high temperature strength, creep resistance,
and oxidation resistance is needed. Techalloy has a broad line
of coated electrodes and solid wires in stainless, duplex, super
and nickel alloy grades for the variety of service conditions present
in the chemical industry.
The Pharmaceutical Industry depends on stainless steel vessels for
mixing components and maintaining purity. These stainless vessels
are typically made of 316L and are successfully welded with Techalloy
316LHS welding wires. The high silicon content of the weld wire gives
the desired smooth flat contour to minimize finish grinding and polishing.
