Description

Post Forge Operations

By providing heat treatment services in-house, NKH is able to maintain greater control over heat treating process. The facility comprise batch furnaces both oil fired & electrical, continuous electrical heating furnaces, solution treatment etc. to carry out annealing, Normalising, hardening, tempering, iso-thermal annealing, solution treatment etc. or other operations as specified by our customer. Close temperature control and process monitoring with the help of temperature recorders ensures uniform properties duly supported by evaluation of metallurgical properties through representative test piecesand test accordingly mentioned below on the available facilities provided by our Facilitation center, which is NATIONAL ACCREDITION BOARD FOR TESTING AND CALIBRATION LAB (NABL) APPROVED.
