Chrome rings on the other hand require a coarser finish usually achieved with 280 grit stones before they agree to seal properly.
Chrome moly piston rings.
Cast iron by nature is very brittle and therefore not as strong as gas.
As we ll see the process is somewhat specific and less than rewarding if you screw it up.
At hastings we manufacture a bold and broad offering of piston rings one that spans thousands of applications for virtually any engine.
The face of the top rings in these sets are electroplated with chromium to provide a surface.
According to joe moriarty of tse racing engines greenland nh about the only applications.
The current je piston catalog lists a multitude of ring materials which may appear at first to be a daunting challenge.
The first is carbon s teel which is a much more malleable material than cast iron is able to handle higher temperatures without losing temper and is better able to withstand bouts with detonation.
With the most comprehensive line of piston rings compression rings and oil rings in the world we have a piston ring for practically any application racing automotive heavy duty transportation agriculture industrial small engine and more.
Chrome file fit ring sets are listed by bore diameter and list available over sizes.
A great way to take full advantage of the 21st century engineering that goes into piston rings is optimize the break in ring seating procedure.
This goes way beyond just choosing the right break in oil although that s an excellent start.
Prior to the advent of moly chrome plated top rings enjoyed widespread use in high performance engines.
