Staybrite® 4435WCQ+ is a state-of-the-art, fully austenitic, remelted stainless steel (ESR), CrNiMo type with about 18 % Cr, 14 % Ni, 2.7 % Mo.
Excellent polishing is one of the main requirements for the highly qualified materials used in the watch industry. This is why Staybrite® 4435WCQ+ has been specially developed: A very high polishability and improved corrosion resistance, for the production of cases, bottoms, rings, circles, and watch straps.
The obtaining of a polishing of very high level and an incomparable shine, results from a specific chemical analysis and a very great mastery of the remelting process of the alloy. This allows also to guarantee a homogeneous and controlled structure (inclusions) as well as a very fine grain and the absence of ferrite.
Staybrite® 4435WCQ+ was developed by Hempel Special Metals AG, Dübendorf/Zürich, Switzerland.

Staybrite® 4435WCQ+ must be annealed under the same conditions as standard grade 1.4435WCQ. From
Temperatures of 1000-1050°C are recommended with fast cooling.
Staybrite® 4435 WCQ+ is a material with a controlled and fine grain size, thanks to the remelting process.
(thickness 6 and thinner) and this allows for optimum cold forming, better corrosion resistance and a better polish.
