Nitriding 135 parts also retain case and core properties at temperatures up to 1000°F and typically show less distortion in heat treating than similar parts fabricated from alloys requiring quenching and tempering to achieve similar surface hardness. The problem then arises of the cast iron porosity and density. The ability of the nitriding to nitride cast iron has been known for many years and is not new. Also note that nitriding components after the process can slightly increase their volume – approx. In this way, the product achieves a much higher hardness of the top layer compared to carbon steels or steel for thermal improvement.

Metallurgist Adolph Machlet developed nitriding by accident in 1906. During treatment, nitrogen diffuses into the steel surface, increasing its hardness and wear resistance. • Quality and integrity of the steel surface precleaning prior to nitriding • Consistent steel chemistry to maximize “nitridability” The Pioneering Work of Machlet In the early years of the 20th century, Adolph Machlet worked as a met-allurgical engineer for the American Gas Company in Elizabeth, NJ. Apart from the basic grades - 38HJ, 38HMJ, 33H3MF, materials such as 40H2MF or 35HM are also nitrided. Nitriding Process. T: +49 541 / 357 39-0 sales@abrams-industries.eu • NITRODUR 34 CrAlNi 7 Al-alloyed nitriding steel grade for large cross-sections. There are two general types of nitriding processes: 1. Thus, nitriding is similar to carburizing in that surface composition is altered, but different in that nitrogen is added into ferrite instead of austenite. Nitriding Steel With a top apparent acerbity nitriding steel grades activity added chafe resistance Nitriding steel stockholders and suppliers, carrying to the accomplished of the India. N was observed [2]. By using special steel grades the surface hardness of nitrided components can be very high, say 1100 Vickers compared to 750-800 Vickers for a carburised and quenched structure. NITRIDING STEEL #135 MODIFIED: Nitriding #135 steel is a modification of AISI 4140 specifically designed to be nitrided for high surface hardness and abrasion resistance.

Abstract The article describes the results of investigations of controlled gas nitriding processes of alloyed structural steel grades 40HM and 38HMJ, used for machine components exposed to corrosion, wear and contact fatigue in service. Other advantages of nitriding steel are increased abrasion resistance, higher sliding properties of the hardened surface and increased fatigue resistance. During the whole process, the steel acts as a catalyst for ammonia decomposition, and before the nitrogen molecules are joined, the atoms are absorbed into the surface of the product in the interstitial spaces of the spatial net creating dispersion and hard nitrides. Nitriding materials include a number of steel types: NITREX METAL INC.Tel: +1-514-335-7191Toll free (Canada/ USA only): +1-877-335-7191Fax: +1-514-335-4160 | send e-mail. The nitride hardening process integrates into the bulk material, allowing the portion of metal below the surface layer to remain soft. The process of nitriding steel begins by heating parts in a furnace to a relatively low temperature (between 950 and 1,100 degrees Fahrenheit, depending on a part’s intended use) compared to other heat treatment methods. This alloy can be age hardened to very high strengths while providing very high surface hardness through nitriding. Divisions of ABRAMS Industries GmbH & Co. KG Hannoversche Str.

For alloy steels containing strong nitride-forming elements. Special nitriding steels such as Nitralloy. ALLOY STEEL. The outer layer that is a relatively homogeneous layer is referred to as bonding layer and below it is a diffusion zone in which the concentration of the diffused nitrogen content decreases with an increase in depth. We achieve very defined properties as a result of precision alloying, process control and procedures for melting, forming and heat treatment. The nitrid-ing temperature for most steels is between 500 °C and 550 °C. Low-temperature plasma assisted nitriding is a very promising technique to improve surface mechanical properties of stainless steels, keeping unaltered or even improving their surface corrosion resistance. Common nitriding steel grades are generally medium carbon alloy steel types that have strong nitride-forming elements such as aluminium chromium, vanadium and molybdenum. Elements C Mn Si Cr Mo P S Spec. Gas nitriding can be applied to unalloyed steels and irons to produce a corrosion- and wear-resistant nitride layer. Prior to nitriding, the product should be carefully cleaned of rust, grease and oil, sharp edges causing material fragility, decarbonized surface should be cleaned leaving the finished product practically ready.
