The mechanical seal of floating roof 20crmo relies on mechanical force to press the sealing steel plate tightly against the tank wall, so that it can slide on the tank wall and avoid gap as far as possible. However, mechanical seal has high requirements for the geometry of storage tank and poor adaptability, so mechanical seal is rarely used in newly built floating roof 20crmo.

20CrMo alloy steel is used in the manufacture of non-corrosive media in chemical equipment and high pressure pipes, fasteners, steam turbines, boiler blades and forgings with working temperature below 250 °C, and important carburizing parts such as gears and shafts in general machines.See all results for this questionRelated searches for 20crmo20crmo equivalent20crmo steel20crnimo steel equivalentscm20 steel equivalent20mocr4 steel equivalent15crmo20cr steel4137 material vs 4140 materialProperties of 20CrMo steel plate steel plate,Properties of 20crmo20CrMo steel plate is a kind of low carbon steel. Because of its low carbon content and low manganese and silicon content, 20CrMo steel plate usually does not produce severe hardening or quenching structure due to welding.

A nanostructured surface layer was produced on an 20CrMo steel plate by means of ultrasonic shot peening (USSP) treatment. Plasma nitriding of the treated and un-treated sample were investigated by using structure analysis (X-ray diffraction, optical microscopy, and transmission electron microscopy ) as well as hardness measurements. It was found that a nanostructured surface layer sample 20crmoAuthor: Jian Sun, Jing Zhang, Wei Ping Tong, Liang Zuo, Ji Cheng HePublish Year: 2012Influence of Retained Austenite on Fatigue Performance of 20crmoOct 11, 2019 · SAE 8620 and 20CrMo materials were subjected to carburizing process to obtain the identical hardened layer of HRC 61-64. The carburized surface and core properties of the materials were examined and characterized through optical microstructure to measure the presence of cementite carbides and Retained Austenite (RA).Henan Xinlianxin Steel Co., Ltd20CrMo 30CrMo 35CrMo 20Cr 40Cr 20Mn2 40Mn2 16CuCr RQ65 50Mn2V 50Mn2Nb B61N-S SC460 21CrMo10 38CrMoAl 35SIMn 25C3MovA 20CrMnMo 21Cr1MoV 30CrMnSiA 35CrMnSiA 7.

1. GB T-3077 20CRMO standard applies to manufacture of bearing ring steel pipe rolling elements made by high-carbon chromium bearing steel processed with hot rolled forged round, steel wire, cold rolled. Continuous casting steel is not recommended to be the material of balls. 2.Failure Analysis on the GCr15 Bearing Steel and the 20CrMo 20crmoFailure analysis on the GCr15 bearing steel and the 20CrMo carburized steel nuts was performed after two sets of fatigue tests of GD8020×1100 ball screw pair. By means of scanning electron microscopy observation, energy dispersive analysis and microhardness testing, it is found that there is an obvious indentation, slight pitting and microcracks on the raceway of the GCr15 bearing steel nut 20crmoCited by: 1Publish Year: 2014Author: Yu Hong Gai, Ye Yan, Cheng Nan Li, Bao Min Li, Wei Du, Mu Sen LiEvaluation of surface-modified 20CrMo by plasma nitriding 20crmoDec 01, 2012 · For the 20CrMo steel sample, the increased hardness may be attributed to the grains refinement in the surface layer and the work hardening. To distinguish the effects of work hardening and grain refinement, the relationship between the hardness and d 1/2 ( d is the grain size) was examined, and the result is shown in Fig. 4 .Cited by: 19Publish Year: 2012Author: J.
