Overview of nitride steels
Group nitride alloy steels usually include medium carbon steel, lagerwey aluminum, chromium, titanium, vanadium and molybdenum (less Nickel). From these steels produce products that are in the process of operation are subjected to significant shock and alternating loads, accompanied by intense wear of the working surfaces. Such products include body bandages punching tools impact (for example, cold forging machines), camshafts, valvetrain bushings, parts gear.
The marking of such steels does not reflect the fact nitriding. A typical medium-alloyed structural steels, for which nitriding is most effective considered brand 30KHGSA, 38ХМЮА, 35ХГТ, 40KHN, 50KHFA and the like.
The optimum modes of termoobrabotki nitride steels is as follows:
Preliminary annealing, prior to machining of the workpiece, if it is provided by technological process;
annealing to obtain a steel of martensitic structure;
Nitriding according to any method — liquid, gas, ionic, of electric arc.
The criterion of suitability of the steel for subsequent operation is parametr superficial Rockwell hardness (should be below 60…62 HRC, but not more than 67 HRC, otherwise the finished part will be exposed to fragility). Critical articles after nitriding needs to be tested for fatigue strength. The surface must be solid, and the core was quite viscous (structure — sorbitol with a hardness of 32 to 40 HRC).
To by structural alloy steels subjected to nitriding, the company offers Electrocentury-steel. The vendor provides delivery of the metal at any point specified by the client.
Examples of the application of nitride steels:
Details of fuel pumps, cylinder liners, powerful engines, spindles 38ХМЮА;
Crankshafts — 18Х2Н4А;
Turbine parts and steam power plants, working for wear in corrosive environments — 12H13…30X13;
High-temperature steel — 15KH11MF;
Gear — 18HGT.
To by structural alloy steels subjected to nitriding, for the price the manufacturer offers the supplier company Electrocentury-steel. Ensured prompt delivery of products to any place specified by the consumer.
