Through Surface Hardening (TSH)

TSH Technologies, Inc. is a subsidiary of ERS Engineering Corporation and exclusively offers the Innovative TSH Technology.

Innovative contour hardening process that utilizes advanced steel technology
Parts are through heated and controlled water quenched resulting in surface harden layer profiling of part
TSH material with heat treat technology is an alternative to carburizing and conventional induction hardening
Novel steel metallurgy leading to lower cost, low hardenability (LH) steels and superior component metallurgy
