2021-6-17 Cyaniding is a case hardening process in which both C and N 2 in form of cyaniding salt are added to surface of low and medium carbon steel. Sodium cyanide or potassium cyanide may be used as the hardening medium. It is a process of superficial case hardening which combines the absorption of carbon and nitrogen to obtain surface hardness.

2021-6-21 Quenching is usually accomplished with a water spray introduced at the proper time through jets in or near the inductor block or coil. In some instances, however, parts are oil-quenched by immersing them in a bath of oil after they reach the hardening temperature. Summary. This article described the primary methods of steel surface hardening.

2014-11-5 Hardening is accomplished when the high-carbon surface layer is quenched to form martensitic case with good wear and fatigue resistance superim-posed on a tough, low-carbon steel core. Of the various diffusion methods (Table 2), gas carburi-zation is the most widely used, followed by gas nitriding and carbonitriding.

2021-6-21 This process is similar to cyaniding except that the absorption of carbon and nitrogen is accomplished by heating the part in a gaseous atmosphere containing hydrocarbons and ammonia. Temperatures of 1425-1625°F (774 to 885°C) are used for parts to be quenched, and lower temperatures, 1200-1450°F (649 to 788°C), may be used where a liquid ...

2021-1-1 As it is a austenitic stainless steel it cannot be subjected to heat treatment process, so a case hardening process called cyaniding is used to improve the properties. The following conclusions has been made. 1. By performing liquid cyaniding process it is observed that specimen treated for 120 min has a case depth of 17 µm. 2.

2021-6-21 ADVERTISEMENTS: 1. Main aim of hardening tools is to induce high hardness. The cutting property of the tool is directly proportional to the hardness of the steel. 2. Many machine parts and all tools are also hardened to achieve high wear resistance. Higher is the hardness, higher is the wear and abrasion resistance.
