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&T | Raise tensile and yield strength, elongation and reduction of area. Hardness to your specified HB / HRC. |
|---|---|
| Low-alloy upgrade | Q345B quenched & tempered up to Q390 / Q420 / Q460 / Q500 / Q550 / Q620, grades C / D / E |
| Low-temperature impact | Guaranteed impact energy at −20 °C / −40 °C, acceptance per EN or ASTM |
Range
| Processes | Normalizing · annealing · quench & temper · quenching · stress relief |
|---|---|
| Grades handled | 20# · 45# · 40Cr · 42CrMo · 35CrMo · 27SiMn · 30CrMnSiA · 20CrMnTi · Q345B/C/D/E · Q390 series |
| Outside diameter | Φ40 – 630 mm |
| Wall thickness | 10 – 70 mm |
| Length | Full lengths up to 14 m in a single furnace charge — no batch splitting |
