10 Times the Wear Life of Conventional
Mild Steel

JADCO QT-PLUS wear steel combines a specific chemistry and unique heat treating process to produce a premium-quality grade of alloy steel that’s unmatched in the industry.

Although QT-PLUS offers outstanding abrasion and wear resistance, parts manufactured from QT-PLUS remain highly ductile because QT-PLUS combines the abrasion resistance of 500 bhn with the ductility of 400 bhn.

QT-PLUS steel plates come in a varied of standard or cut-to-size dimensions.

Why Specify QT-PLUS?

  • > Weldability
    QT-PLUS exhibits excellent weldability. Cheaper steels have carbon contents as high as 50%, resulting in poor weldability, and are susceptible to cracking.

  • > Toughness
    QT-PLUS is extremely tough. Cheaper steels typically have little or no alloy, and high carbon content, that reduce toughness.

  • > Through-Hardness
    QT-PLUS chemical composition produces a material that retains its inner toughness. Cheaper steels possess a lean chemistry that eliminates through-hardness.

  • > Consistent Properties
    QT-PLUS has uniform characteristics. With cheaper steels, lack of proper heat treating creates “hard” and “soft” spots.

  • > Quality Parts
    QT-PLUS is manufactured under the strictest quality standards. With cheaper steels, lack of quality control results in plates that are warped or wavy, making installation dicult and costly.

  • > Fabrication
    QT-PLUS is manufactured from a high quality premium steel that can be easily fabricated. With cheaper steels, forming, machining and welding are more difficult.

FORMING PROCEDURES FOR QT-PLUS®

QT-Plus® is cold formable with the proper equipment and material preparation. The material toughness allows it to be rolled or formed for almost any application. We recommend a minimum radius of 8T across the grain. Please follow the outlined procedures to minimize cracking concerns.

  1. Plate must be bent in direction perpendicular to the grain.
  2. Grind corners of gas-cut edge 12" beyond bend area before bending
  3. Grind any notches off gas cut surface in area of bend
  4. Can pre-heat to 300F to improve formability....but not over 400F
  5. Use as wide a female die (throat) as possible
  6. Use as wide a male punch as possible (3" radius rather than a 1" radius)
  7. Bump in several bends rather than one large one
  8. Look at outside radius surface before bending and grind out any gouges
