ULTRA-HOLDER™
A.I.S.I. 4340 Modified Pre-Hard 38/43 RcH
DSS #40U
ULTRA-HOLDER™ is a high strength
holder material and should be used in conjunction with high hard insert materials, where
longer die life and lower maintenance costs are needed. The uniform structure and
alloy content makes it suited to withstanding high service loading and reduces coining on
the parting line. When using ULTRA-HOLDER™ in large holder block
applications, the center hardness is consistently higher than that of standard holder
material.
