Stainless Steel Obtained by Various Nitriding Processes ... because they are softer relative to the other stainless steel grades. Gas nitriding is a form of steel heat treatment in which one uses heat to diffuse nitrogen-rich gas onto the surface of the metal with the intention of hardening it. Click on “Privacy & Cookies Policy” for detailed information on the use of cookies on this website. At these low temperatures, the iron remains ferritic—phase changes that alter the structure of the iron do not occur. 2. Further use: plunger pistons, piston rods, spindles in grinders and milling machines, measuring equipment. Plasma nitriding of the aged A286 resulted in formation of expanded austenite. Low-temperature traditional gas nitriding treatment was conducted by using austenitic stainless steel grade 304. 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. Nitriding 135 is usually supplied in the pre-hardened condition, about 26/30 HRC, ready for nitriding. Chemistry. 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 N is an AOD + VAR low alloy nitriding steel. For alloy steels containing strong nitride-forming elements. Download Datasheet Equivalent Nitriding Steel Grades: European EU EN 31CrMo12 Listed nitriding steel manufacturers, suppliers, dealers & exporters are offering best deals for nitriding steel at your nearby location. Nitriding steel is steel treated by a highly specialized surface hardening process known as nitriding, which is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. Nitriding steels usually contain aluminum – Al, Chrome – Cr, Molybdenum – Mo. During steel nitriding, a layer is formed which can be divided into two main areas. 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. It is often used as gears in the rotorcraft industry.

We stock and supply a wide range of High Tensile, Case Hardening and Nitriding grades suitable for a wide range of industry applications. At this temperature, when nitrogen is diffused into the base steel, the hardening occurs without quenching. 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. The Nitriding process is an established and successful means of generating a hard case on a component. It is often used as gears in the rotorcraft industry. Heat treating it will develop high core strength. 2. ALLOY STEEL. Also note that nitriding components after the process can slightly increase their volume – approx. Rounds.

For high alloy steels, plasma nitriding is preferred to reduce the treatment temperature, increase nitrogen activity and prevent the onset of grain boundary precipitation (Yagita and Ohki, 2010). Steels for nitriding in relation to carbon steels have 2 to 4 times higher hardness and abrasion resistance after imparting properties, and consequently, increased susceptibility to brittleness. Quenching is not required for the production of hard case. Nitriding and Metallurgical Behavior. This diffusion takes place at relatively low temperatures near 524°C (975°F). Apart from the basic grades - 38HJ, 38HMJ, 33H3MF, materials such as 40H2MF or 35HM are also nitrided. There are two general types of nitriding processes: 1.

The grades listed below are the nitriding steels we stock as standard ready for processing and delivery. valve steels) etc. Nitriding steel: Nitrodur A speciality of Deutsche Edelstahlwerke Whenever machines and components are subject to high surface stresses and dynamic loads, it is vitally important that special high-performance steel is used. Other unevenness must be leveled with chip or grinding and stressed by tempering at a temperature above the nitriding temperature. Construction components: valve spindles and plates. Nitriding steel is produced when steel is subjected to the nitriding process. Nitriding 135M is suitable up to 1000°F. Before Nitriding the chemical composition (grade confirmations) of chosen steel material EN 19 was studied by using wet chemistry method (4, 5,6,7,8 & 9) and the percentage of assigning elements are shown in the Table 2.1 Table: 2.1 Chemistry of EN 19 Grade Steel EN19 25mm (%) Percentage of Assign. grades are available where companies have developed specifications to overcome specific problems associated with either mechanical properties or processing. Depending on the steel grade OvaX 200 is our advanced material to meet this need. 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. valve steels) etc. Grade Applications; 1.8550: Nitriding steel which makes it possible to achieve nitrided layers with a very high lavel of hardness. Nitriding is a surface-hardening heat treatment that introduces nitrogen into the surface of steel at a temperature range (500 to 550°C, or 930 to 1020°F), while it is in the ferrite condition. 2- Are there any risks in liquid nitriding of carburized 4140 steel? During treatment, nitrogen diffuses into the steel surface, increasing its hardness and wear resistance. Nitriding Process. Thus, nitriding is similar to carburizing in that surface composition is altered, but different in that nitrogen is added into ferrite instead of austenite. 3.2 Gas nitriding Gas nitriding is a case-hardening process whereby nitrogen is introduced into the sur - face by holding the steel at a suitable tem-perature in contact with a nitrogenous gas, usually ammonia. Nitriding 135M is a low alloy nitriding grade that provides a high case hardness while still maintaining high strength in the core. Precision Nitriding for Your Critical Specs.

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. High alloy steels: tool steels, heat-resistant steels (e.g. IF YOU CONTINUE TO USE THIS SITE, YOU AGREE THAT THE COOKIES WILL BE STORED ON YOUR DEVICE, Boiler steel for high temperature applications, Hadfield Steel - high-manganese hard-wearing austenitic. Nitriding can also increase the corrosion resistance of a component. Stainless steels (ferritic, martensitic, austenitic, PH grades) Cast iron (grey or nodular) EN40B in T condition has a tensile of 850-1000 N/mm². OvaX 200 is a perfect steel for plasma, gas or nitro-carburising. In this way, the product achieves a much higher hardness of the top layer compared to carbon steels or steel for thermal improvement. Table 10.2 gives some applications of a number of nitrided steel grades for surface and volume fatigue life improvement. The nitriding steel typically in the softened state is first subjected to a thermal improvement process after pre-machining and cutting of long products into shorter components. Construction components: valve spindles and plates. The steel grades above can all be made as BQ-Steel, IQ-Steel or M-Steel. The nitrid-ing temperature for most steels is between 500 °C and 550 °C. Nitriding is the process of saturating the top layer of a product by penetrating the nitrogen atoms most often in a dissociation stream of ammonia. All rights reserved. The internal structure of the products is exposed to the frequent occurrence of cracks when used inappropriately. Nitriding is a surface-hardening heat treatment that introduces nitrogen into the surface of steel at a temperature range (500 to 550°C, or 930 to 1020°F), while it is in the ferrite condition. The nitride hardening process integrates into the bulk material, allowing the portion of metal below the surface layer to remain soft.
