  • Characteristics and Application of 9Cr18 Stainless

    9Cr18 stainless steel ball. 9Cr18 stainless steel ball is a spherical iron-iron wear-resistant body which is mainly composed of carbon, chromium, manganese, molybdenum and the like, and is formed by forging, spinning, rolling, grinding and casting. It is crushed today. The most important part of the industrial and bearing industry.

  • Surface modification of 9Cr18 bearing steels by a

    2000-6-1 · In the aerospace industry, 9Cr18 martensitic stainless steel (AISI 440) is commonly used as a bearing material. Because of its ability to rapidly treat irregular industrial components, plasma immersion ion implantation (PIII) is an effective method to improve the wear resistance of 9Cr18 precision bearings and prolong their working lifetime.

  • Schweinfurt Raid - WW2 Timeline (October 14th, 1943)

    2000-6-16 · Coupons of 9Cr18 bearing steel composition in wt.%: Si-0.8, Mn-0.72, P-0.035, S-0.03, C-0.96; and Cr-17.8, Fe-79.655 were cut from a real bearing ring in a. quenched-and-tempered state. The samples were grounded and mechanically polished to a surface roughness, R a, of 0.05 mm. They were then cleaned with acetone before PIII. Implantation was carried out

  • Death on the High Road: The Schweinfurt Raid

    American planners, including Generals Ira Eaker and Carl ‘Tooey’ Spaatz, countered that precision attacks against selected industrial targets like oil production facilities, aircraft and ball bearing plants were the best use of bomber strength. ‘It is better to cause a high degree of destruction in a few essential industries…than to cause a small degree in many,’ the USAAF Committee of Operations Analysts …

  • Tribological mechanism and property of 9Cr18 friction

    2004-1-16 · However, one main existing application problem is that the poor tribological performances of 9Cr18 steel can induce a bearing failure, which will impact the machine and the reliability of the whole system . Previous studies have revealed that failure of bearings occurs mainly on the surface or in the near-surface region . Consequently, enhancing the surface properties by surface treatment is a good way of prolonging the lifetime and working reliability of bearings.
