ENDURA Steel

The Premiere Wear Resistant and Work Hardening New ENDURA Steel

If you require a steel which is very tough, very hard, very abrasion resistant, easy to process and weld, and is competitively priced, then TITUS ENDURA STEEL is the answer.

 

ENDURA Steel Advantages

  1. Best Wear Resistance of any abrasion resistant plate
    • 8 times greater wear than mild steel
    • 2-4 times greater life than conventional 500 BHN steels
  2. Reduce plate thickness up to 25% vs AR 500 (ie. 2″ -> 1.5″)
  3. Ability to “Work Harden” from 470 BHN to 560 BHN
  4. Ease of Processing compared to conventional 500 BHN steels
  5. Can be Welded with Low Hydrogen Rod providing a major cost saving
  6. No pre or post heating required for welding

 

Micro Structure

Due to precise and uniform addition of Nickel, Chrome, and Molybdenum, ENDURA has:

  • Superior Wear Ability
  • Superior Work-Hardening
  • Superior Work Ability
  • Superior Weld Ability
  • Thinner Plate Thickness

 

Trip Effect

ENDURA’s unique Micro Structure is uniform and homogenous making it highly abrasion resistant. This is due in part, to the fact that ENDURA is “oil- quenched’ during heat treatment. Conventional AR 500 steels are “water- quenched” resulting in an irregular and distorted micro structure.

 

 

ENDURA’s revolutionary T.R.I.P. effect (Transformation Induced by Plasticity) reduces tearing, shearing, and chip removal.

ENDURA vs AR 500

Manufacturing

ENDURA is OIL QUENCHED resulting in a “fine Homogenous Micro Structure” for improved hardness and easier processing. Small and even dispersion of Carbides provides hardness and abrasion resistance, less brittleness and less cracking. Homogenous Micro Structure also provides “elasticity effect” which limits gouging, tearing and shearing. Limited amount of “Unstable or Retained Austenite” reduces chipping and cracking.

AR 500 is WATER QUENCHED resulting in a “course non homogenous microstructure”. Large and uneven dispersion of carbides provides embrittling effect prone to cracking Pockets of “Unstable or Retained Austenite” causes chipping and cracking.

Plate thickness can be reduced up to 25% vs AR 500 (ie. 2″ -> 1½), saving costs and increasing payload.

Please Note:

ENDURA’s work-hardening properties – Lower initial hardness for easier processing, but increases 50-70 brinell points with impact.

ENDURA is 1/3 more resistant to impact and cracking.

ENDURA is 7% tougher before ultimate failure of the steel.

ENDURA has 5-6% more resistance before deformation of the steel begins.

ENDURA is 50% more elastic thereby reducing cracking and breaking.

Please Note: ENDURA is easier to bend and less prone to cracking

Bending radius can be reduced by bending at right angles to the grain or direction of rolling
