Heat Treatment

The same 42CrMo pipe in as-rolled versus quenched-and-tempered condition is effectively two different materials — yield strength can differ by a factor of three or more. We heat treat to the delivery condition your application requires, with full process records.

What heat treatment can achieve

Alloy pipe Q&TRaise tensile and yield strength, elongation and reduction of area. Hardness to your specified HB / HRC.
Low-alloy upgradeQ345B quenched & tempered up to Q390 / Q420 / Q460 / Q500 / Q550 / Q620, grades C / D / E
Low-temperature impactGuaranteed impact energy at −20 °C / −40 °C, acceptance per EN or ASTM
