Nitriding / Nitrocarburizing Control Upgrade

RFQ

Nitriding is used in the aerospace, automotive, defense, energy, gearing, industrial, plastics, and tooling industries for applications ranging from crankshafts to camshafts, die-cast dies, extrusion dies, forging dies, gearbox assemblies, gears, injectors, landing gears, molds, valve parts, springs, tools, and many more.

Nitriding/nitrocarburizing materials include a number of steel types:

Carbon steels
Alloy steels that can be hardened
Special nitriding steels such as Nitralloy
High alloy steels: tool steels, heat-resistant steels (e.g. valve steels) etc.
Stainless steels (ferritic, martensitic, austenitic, PH grades)
Cast iron (grey or nodular)
