How we fixed a hardness inconsistency that was cracking molds at 800 cycles
A German mold maker had received two shipments of H13 with hardness readings swinging from 44 to 51 HRC on the same bar — and two molds had already cracked in service.
We sourced premium ESR-remelted H13 instead, arranged a Bureau Veritas hardness survey across five points per bar, and delivered full documentation within 5 days of order confirmation.
Zero variance issues reported. Now a repeat buyer — 68 tons annually over 18 months.
