CHROMECORE 430N-S

CLASSIFICATION

EN 14700 T Fe7

DESCRIPTION

• Nitrogen bearing tubular wire for submerged arc cladding steel mill rolls
• Designed to produce a weld metal chemistry in one layer similar to 414N-S all weld metal chemical composition

APPLICATIONS

Enhanced wire chemistry is obtained by over-alloying the consumable according to typical dilution levels observed in open arc welding.
Chromecore 430N-S is suitable as a buffer material onto previously unclad rolls prior to the application of Chromecore 414N-S.
Chromecore 430N-S is intended to replace Chromecore 430-S since it provides a uniform microstructure and properties from the fusion line to the top machined surface.
