CST’s Ni-Surf process for gas nitriding is a contemporary multi-stage procedure for case hardening alloy steels such as 4140 and 4340, special nitriding … He discovered that the nitriding process … After gas … Gas Nitriding is a thermo-chemical case hardening process. The entire nitriding process is executed in an automatic, self-adjusting and operator independent manner. The operating process temperature is lower than other surface diffusion processes. Typical gas nitriding depths are .010”-.020”. The process temperature range is 500˚C – 530˚C (930˚F – 975˚F). Fry then investigated the effects of alloying elements on surface hard-ness. Gas Nitriding Nitriding is a highly specialized surface hardening treatment that produces a thin but high hardness case on a wide variety of steels. The gas nitriding process (also called “ammonia nitriding”) provides a way to case harden the surface of steel components, hardening them to better resist scratches, abrasions … Gas nitriding of sintered steels with low density is not recommended. Process Selection and Quality Control. Heat treating process control software: Designed to monitor, control and regulate all nitriding process … The process of case hardening via gas nitriding is performed by heating previously hardened parts in a controlled atmosphere to a temperature below the previous tempering temperature. For gas nitriding, our Ohio facility is well located for Midwest manufacturers, offering one of the largest nitriding departments in the country. The gas nitriding process control systems are designed to provide a fully automatic operation. Gas Nitriding is a low temperature case hardening process that is ideal for producing hardened surfaces on pre-heat treated alloy steels such as 4140 and 4340, pre-heat treated tool steels such as H13, and specialty grades such as Nitralloy 135M. The nitrogen —which is soluble in iron at nitriding … The Gas Nitriding Process. Gas Nitriding Process. Dimensional distortion is minimal in the process … Disassociated Ammonia is the source of atomic Nitrogen that is diffused into the part surface to create a hardened case that is wear resistant and corrosion resistant. The process temperature for Gas Nitriding … Thus was developed the single-stage gas nitriding process as it is known today. Gas Nitriding requires precise control of the treatment process. The temperature is held for a length of time proportionate to the case depth requirement. Gas nitriding is a case hardening process where nitrogen is imparted to workpieces heated in furnaces at around 1,000 degrees Fahrenheit. Home; Gas Nitriding; Gas Nitride case hardening is a method of imparting very high hardness to the surface of steel alloys and is used to harden a vast array of components for many … posted On Tuesday, December 1, 2020 in Blog While every surface treatment has its advantages and disadvantages, gas and ion (plasma) nitriding are often compared when engineers … The significant advantage of nitriding over other surface … use hydrogen as a dilutant gas. Commonly, the definition of term ‘nitriding’ is synonym to gas-nitriding of nitriding (alloy) steels (also called nitralloys), i.e., it is understood as the enrichment of solid steel surface with nitrogen by heating it in an atmosphere of NH 3 gas … Corrosionpedia explains Gas Nitriding In the process of gas nitriding, nitrogen is introduced into the surface of a solid ferrous alloy by maintaining the metal at a suitable temperature while in contact with a nitrogenous gas… Gas Nitriding Process. Ammonia (NH3) is injected into the furnace during heating and breaks apart upon contact with the workpiece.
