Grade DD (Deep Draw)
Specialised Cr-Mn-Ni grade engineered for severe deep-drawing operations.
Material Overview
Cr-Mn-Ni Austenitic
DD is purpose-built for components that undergo severe cold deformation. The slightly higher nickel and lower carbon content reduce work-hardening, allowing producers to achieve high draw ratios with minimal cracking or earing.
