VDM adopts nitric acid-free pickling
16 November 2020
VDM Metals Group, a German manufacturer of nickel alloys and special stainless steels, has adopted Henkel´s next-generation nitric acid (HNO3) free Bonderite C-CP (Cleanox) pickling process for dedicated wire products. The Bonderite C-CP product range answers market requirements within the metals industry to significantly increase the sustainability value of their production processes.
The Cleanox technology has been in use for decades for wires, tubes, coils, bars, and components. It is suitable for all stainless steel grades and can be used in multiple applications, including immersion, spray, continuous line, or batch solution processes. VDM Metals, based in Werdohl, is using Henkel’s Cleanox technology to pickle rolled wire of high-alloyed materials to ensure compliance with NOx limits.
Henkel´s Bonderite C-CP overcomes the environmental and cost hurdles with its line of nitric acid-free cleaning technologies. The lower amount of sludge created by the new technology, when compared to the traditional process, is a further sustainability advantage. Furthermore, global process costs are equal to or lower than conventional methods. The Bonderite C-CP process is suitable for any stainless steel or special grade based on austenite, ferrite, martensite, duplex, or super duplex, including high-chromium AISI/SAE 4XX qualities.
