Factory supply Customized Cobalt Based Alloy Rod Stellite 6B Round Bar
1. Stellite alloys have higher melting points than nickel (or iron) alloys ,This gives them the ability to absorb stress to a higher absolute temperature .
2. Stellite alloys give superior hot corrosion resistance to gas turbine atmospheres , this is due to their high chromium content.
3. Stellite alloys show superior thermal fatigue resistance and weldability over nickel alloys .
---Excellent wear and corrosion resistance even at high temperature up to 800℃
SYTOP cobalt base alloys is a range of cobalt-chromium-tungsten alloys with wear resistance, corrosion and high thermal resistance. It is widely used in oil & gas, machinery, wood cutting, automotive, paper and food processing industry etc.
