Paper and Pulp markets
The pulp and paper market relies on stainless
steel weld wires and electrodes for the conversion of raw materials
into the final products and utilization of the final products.
In the conversion process highly corrosive environments, utilizing
bleaches and highly caustic solutions, require the use of Techalloy
brand stainless welding wires and electrodes to overlay the inner
surfaces of digesters to protect against corrosion.
Stainless grades 309L, 312 and duplex stainless
grades 2209 in diameters of .035” and .045” on 33 lb.
wire basket spools are the most utilized along with 309L-16 and
312-16 large diameter electrodes. Paper printing rolls are often
refurbished utilizing 308L and 316L weld wires with a thermal spray,
mig or submerged arc welding process.
