Stellite® 6 Round Bar Supplier in India
Stellite® 6 round bar (UNS R30006) is turned and machined into valve seats and gates, pump shafts, bushes, pins and other wear components. The cobalt-chromium-tungsten alloy holds a hardness of 36–45 HRC to about 500 °C and resists abrasion, galling and cavitation, so machined parts keep their fit and finish in service where tool steels and stainless would seize or wear. Bar is machinable with carbide tooling and is frequently run self-mated.
