WORKING WITH QT PLUS® WEAR STEEL
FABRICATION INFORMATION
FLAME CUTTING
Easily flame cut QT-PLUS® with oxyacetylene or plasma. Hardening will occur at the edge of the cut, therefore it’s beneficial to pre-heat before flame cutting (300°F) or allow enough stock to get below the hardened edge.
The minimum plate temperature prior to thermal cutting should be +60°F.
Note: At JADCO, high-definition plasma is used to burn, and the material is under water to decrease distortion of the heat-affected area. For plates ¾” and thicker, preheat the plate to 300°F to prevent edge cracking. When preheating the plate do not heat directly with a torch, use indirect heat to heat evenly over the entire plate.
MACHINING
QT-PLUS® may be machined and drilled using conventional methods with proper tooling and speeds.
Please contact your JADCO representative to discuss your specific requirements.
FORMING
WELDING
QT-PLUS ® has a low carbon content which allows ease of weldability. When welding QT-PLUS® it is recommended to use JADCO FUSION™ Universal, a high strength, work hardened stainless steel that can be welded to dissimilar metals, designed for harsh working environments. Typical low hydrogen rods/wires such as E7018 or E8018 weld rod, E71T flux core wire and ER70S solid wire can also be used. Pre-heat to 250°F through thickness within 3 inches of welding zone before welding. Slow cool welds with blankets. Welds in restraint should be avoided.
QT-PLUS® has the mechanical properties for the harshest environments.
