CHROMEWELD™ Complex
CHROMEWELD™ Nb-Plus is a Niobium (Nb) carbide overlay plate optimized for fine particle and extreme abrasion. CHROMEWELD” Nb-Plus weld deposit consists of primary Chromium carbides with added Niobium carbides in an austenitic matrix. CHROMEWELD” Nb-Plus increases wear life
significantly due to the enriched, fine particle abrasion resistant deposit. CHROMEWELD™ Nb-Plus also increases wear resistance at elevated temperatures due to its enhanced chemistry.
GENERAL INFORMATION
• Hardness ranges from 63-68 HRC, based on weld deposit thickness.
• Remains abrasion resistant at temperatures up to 650°C.
• Diplays excellent fine particle abrasion resistance and will withstand continuous moderate impact. Overlay is a composite of Chromium and Niobium in a Chromium austenitic matrix.
• Standard Thickness Ranges from 3mm on 3mm through 12mm on 12mm. Backing Plate can be customised as per the user requirement to Stainless Steel, Other Carbon Steels.
• CHROMEWELDTM Nb-Plus is also available in Smooth Finish with Anti-Hang Up Properties enabling greater flowability.
