430DDQ – 1.4016

430DDQ – 1.4016

(South America offer) A variant of our 430 grade, this 16% Chromium Ferritic Stainless Steel offers increased forming and drawing capabilities.

Main features

Good resistance to both corrosion (in moderately aggressive environments) and high-temperature oxidation, enhanced cold formability, an attractive surface appearance upon delivery without additional finishing. 430DDQ also has good resistance to high temperature oxidation. This grade serves as an alternative when the 430 is at the limit of its forming and drawing capabilities. Thanks to its improved forming properties, our clients can reduce their non-quality and internal rejection rates when 430DDQ is used on parts that are difficult to form. Producing complex formed parts in regular thicknesses enables more creativity and evolution in terms of design. It is particularly beneficial in strengthening the structure with the use of tighter radii, as well as reducing the thickness of parts that have a similar or identical geometry to those of 430. Can replace 439 grade in more complex parts if a stabilised grade is not required for welding purposes. Delivered by Aperam South America.
