52100 Aircraft Quality Alloy Material Information

52100 aircraft quality alloy material is a high carbon, high chromium electric furnace material (meeting Bearing Quality standards).  These standards require special melting, teeming, heating, rolling, cooling and conditioning practices; also thoroughly examination for minute imperfections.  52100 material develops high hardness and exceptional resistance to wear and abrasion.  In smaller sections it has high compressive strength.  Because of the high carbon content, bars are furnished in a spheroidize annealed condition in order to provide the best possible machinability.  This combination of properties makes 52100 material an ideal choice for a variety of applications such as races and balls or rollers in anti-friction bearings, oil well perforating gun bullets, dies, punches, shear and cutting blades, cam rollers.

 52100 material is very hard to weld.  It can be welded by all of the common welding processes providing the section is preheated and stress relieved after welding.  The grade of welding rod to be used depends upon thickness of section, design, service requirements, etc.

 Hardening 52100 material depends on the quench requirements.  For oil quenching, hardening is in the range between 1500 – 1600 F.  For water quench, hardening is in the range between 1425 – 1475 F.  Average as quenched RC hardness 63.
