Case 550 Core 200- Its machineability is poor.Heat Treatment:- Finish by water quenching from 1050 °C to keep the carbides in solid solution.Applications:After a properly controlled heat treatment, this steel is characterized by high strength, high ductility and excellent resistance to wear and thus it finds uses such as in- Jaw crushing machinery.- Digger teeth, elevator chains.- Railway track work.- Dredging equipment (buckets, tumblers, etc.)b) High Carbon, High Chromium, Wear Resistant Steel [TABLE=align: center][TR][TD=align: left] برای مشاهده این محتوا لطفاً ثبت نام کنید یا وارد شوید. ورود یا ثبت نام [/TD][/TR][TR][TD=align: left]High Carbon, High Chromium, Wear Resistant Steel[/TD][/TR][/TABLE] Chemical composition:C 1.5 to 2.25%Cr 12%Mo 1%V 0.25%- The steel is quenched in oil or air.Properties:- Require slow heating.- Are very deep hardening.- Have low thermal conductivity.- Require careful heat-treatment and avoidance of decarburization.Special carbide present in steel makes it very resistant to tempering, around 58 – 59 Rockwell C being retained after tempering at 315 °C. 4 لینک به دیدگاه
