Mahle performance piston rings

Mahle has introduced new piston rings for the performance market. The rings are made out of SAE9254 steel which enable high velocity oxygen fuel (HVOF) coatings and physical vapor deposition (PVD) coatings to be applied. This base steel allows customers to get advanced second rings from the same steel. It’s Mahle’s first foray into the performance piston ring market.
