What We Do
WE HELP GLASS MANUFACTURERS MOVE PRODUCT
JADCO produces CHROMEWELD™, a chromium carbide overlay plate for all applications but a product that works nice for glass and ceramics. As an industry leader with multiple overlay chemistries, JADCO is able to meet your project requirements. Our in-house fabrication services provide you with a completed product, offering you an all in one provider.
JADCO Wear Solutions for Glass:
When looking at JADCO, there are a few things to consider that we want to point out. We assume you want to evaluate the Nickel content because of the fear of Ni sulphide inclusions but also the wear performance in product life expectancy. When it comes to Ni, the common number that we have worked to as “Glass Industry Standard” is 0.25% Ni maximum allowable in our plate. JADCO does not use or introduce Ni into our CW600 overlay plate but we do make note to users that nickel does occur normally in chromite oxide and there are small trace amounts of Ni found within any manufactures wire that is used in an overlay process. Since JADCO utilizes an open arc weld process to produce our plate, we tend to see even lower amounts on Ni than those manufacturers utilizing a bulk weld process. In understanding this, we set our max allowable limit at an industry standard of 0.25% but control the process to well below 0.20% which has been easily accepted by glass producers. If you have an internal company standard that is different, just let us know and we will be happy to discuss and show how we can accommodate.
The other area to consider is wear performance of the overlay plate. This is the reason we conduct ASTM G65 wear tests and consistently outperform the industry in mass loss comparison. JADCO’s plate is on average 5 to 10 Brinell points higher than other manufacturers which tends to give us better wear life in most applications. The other benefit of a higher wear rate is lower Ni introduction in the process. In other words if the plate lasts longer, or wears less, then it is introducing less “material” into the process. So longer wear equals less Ni introduction. Another way to think about this is if you were using an AR500 type wear steel and the overlay plate outperforms this type of material by 3X plus wear life, the AR500 plate is introducing the possibility of Ni into the process 3X times faster because of the wear given over same time period.
