QT PLUS

Severe Impact and Abrasion Resistant Plate

QT PLUS

Lasts 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. QT-PLUS® wear life is 3 to 5 times longer than AR400 commodity wear steel.

QT-PLUS® is produced to ISO 9001:2015 certified standards ensuring the highest quality.

QT-Plus Liner

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

WHY?

WELDABILITY

The exhibited excellent weldability of QT-PLUS® is due to the tightly controlled carbon range (.24 -.26) and extremely low hydrogen levels, (<4 ppm).

TOUGHNESS

QT PLUS® is extremely tough due to enriched nickel content and the proprietary heat-treatment process.

THROUGH-HARDNESS

The 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.

CONSISTENT QUALITY

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

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

Our QT PLUS® Wear Steel is designed for superior formability when compared to other high abrasion-resistant plates in this class. QT PLUS® is cold-formable. Also, the toughness of  QT PLUS® enables it to be rolled and/or formed for almost any application up to 2” thick. We recommend 8T across the grain and 12T with the grain. For plate over 2” thick, 12T transverse to the grain is recommended.

WELDING

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.

QT PLUS® has the mechanical properties for the harshest environments.
