CHROMECORE R 17 4 PH-S
EN 14700 T ZFe7
• Stainless steel tubular wire for submerged arc cladding
• Martensitic precipitation hardening stainless steel deposit
• In the as welded condition, the deposit can be machined to the exact profile required
• It withstands cavitation and corrosion very well
• Heat treatment at 430 - 470°C is recommended after welding and machining in order to achieve a tempered martensitic structure containing Ni/Cu precipitates
Chromecore R 17 4 PH S is used for cladding or hardfacing steel mill rolls, rebuilding hydro turbine components, shafts, impellers, steam turbine components etc.
