EXTREME Impact and Abrasion Resistant WEAR Plate
Engineered Tough & Ductile, lIke No Other Wear Plate
QT-PLUS® wear life is 3 to 5 times longer than AR400 commodity wear steel.QT-PLUS® proprietary chemistry and unique thermal heat-treating process produces a premium quality severe impact and abrasion resistant plate unmatched in the industry. This incredibly tough and hard steel with extraordinary ductility, is produced with tightly controlled carbon levels for ease of weldability, and excellent formability. QT-PLUS® is alloy rich, and is “true” through-plate hardening…it is supreme quality wear plate, engineered like no other in the world. QT-PLUS® is produced to ISO 9001:2015 certified standards ensuring the highest quality.
Parts manufactured with QT-PLUS® provide outstanding resistance to abrasion and wear and are extraordinarily ductile.
QT-PLUS® plates come in a variety of standard or cut-to-size dimensions. QT-PLUS® plates are stocked in sizes from ¼” up to 5” thick.
QT-PLUS® IS SUPERIOR TO AR GRADE STEELS
WELDABILITYThe exhibited excellent weldability of QT-PLUS® is due to the tightly controlled carbon range (.24 -.26) and extremely low hydrogen levels, (<4 ppm).
QT-PLUS® is extremely tough due to enriched nickel content and the proprietary heat-treatment process.
THROUGH-HARDNESSThe chemical composition of our tough wear steel, QT-PLUS®, produces a product that retains hardness throughout the entire plate thickness. By comparison, the sparse alloy content of commodity-grade steels prohibits through-hardness of the plate, resulting in rapid wear.
Our QT-PLUS® Wear Steel is produced under the strictest quality standards with characteristics that are uniform in every plate, providing reliable predictability for all applications.
By comparison, commodity AR grade steels’ inconsistent heat-treating processes and wide variations in chemistries create “hard” and “soft” spots and plate warping, resulting in rapid, unpredictable wear rates and difficult installations.
WORKING WITH QT PLUS® WEAR STEEL
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.
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.
When welding QT-PLUS® Wear Steel, use E7018 or E8018 weld rod. Rods should be dry-welded on a moisture-free surface.
Pre-heating is preferred to reduce thermal shock (250° is a general rule).
If pre-heating is not possible, a 309 stainless rod/wire is preferred.
Welds in restraint should be avoided.
