X2Cr13 + QT conveyor roller of rolling mill
X2Cr13 + QT conveyor roller of rolling mill:
Material: X2Cr13 + QT conveyor roller
Forgings, Martensitic stainless steel.
The conveyor roller of rolling mill producing process: Forged round of martensite—- Tempered —- Rough machining—- Finishing —-Inspection— Packaging.
The material is a chrome-alloyed heat treatable steel with medium carbon content which is rust proof. It has a good corrosion resistance because of its chrome content in moderate aggressive, non chloric substances like soap, solvents and organic acid.
This material shows its highest corrosion resistance with fine grinded and polished surface. The machinability of the material is comparable with alloyed heat treatable steels and causes no significant difficulties.
The material can be hardened by holding the temperature between 950°C and 1050° C with a subsequent cooling in air, oil or polymer. The strength of the material depends on the tempering temperature.It is usually divided in two heat treatment conditions, QT700 and QT800. This material is used in mechanical engineering and power engineering.
