8620 As Rolled

HOT ROLLED & COLD FINISHED

PACIFIC 8620 is a triple alloyed nickel-chrome-moly steel. It has become the standard alloy grade for carburizing because of its balanced case-core hardenability, availability and moderate cost.

PACIFIC 8620H is rough turned oversize in sizes exceeding 3" diameter. These sizes are also calcium treated, vacuum degassed and ultrasonic tested for optimum machinability, cleanliness and soundness.

This grade is often used in the as received condition where moderate strength with good weldability is required. In sizes up to 2" diameter it can be quenched and tempered to the 100,000 psi yield strength range.
