A sharp strength degradation in this material occurs as the thermal aged strength degradation of 42crmo steel in a thermal fieldWhat is a Graphitization? - Definition from CorrosionpediaMay 27, 2014 · The formation of graphite is due to the nucleation and growth process that occurs when the steel is exposed to temperatures above 800°F (426°C). Graphite is a weak material with very low ductility and low resistance to thermal or mechanical fatigue or shock. Graphitization causes localized and weak areas on the affected steel component.What is Steel Corrosion? - Definition from CorrosionpediaSep 18, 2013 · Slowly it loses its mechanical strength and elasticity. Thus, the useful life of steel structures and other applications are severely curtailed. Hence, there is a need to apply suitable protective coating, depending upon the type of application and environment. Some alloys of steel have certain inbuilt corrosion resistance.

Chuang Wang's 5 research works with 5 citations and 202 reads, including: Strength degradation of 42CrMo steel in a thermal field and its characterization methodCarbon Steel Handbook - OLIweldability, carbon steel is one of the most commonly used materials in the electric power generation industry. Carbon steels in which carbon represents 0.150.35%those used most often as boiler and piping materialsare the focus of this Carbon Steel Handbook. Although carbon steel is available in virtually all product forms, it is theApplication potential of high performance steels for strength degradation of 42crmo steel in a thermal fieldSteel grade 42CrMo has been widely used in China for making high strength bolts. However the resistance to hydrogen induced cracking of this alloy is insufficient for the application. Modification of this steel grade by microalloying allows tolerating up to six times higher hydrogen content without causing severe hydrogen embrittlement.
