ENDURA (creusabro)
The Premiere Wear Resistant And Work Hardening New 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 is the answer.
Endura Advantages
1. Best Wear Resistance of any abrasion resistant plate
- 8 times greater wear than mild steel
- 1 1/2 times greater than conventional 500 BHN steels
2. Ability to “Work Harden” from 470 BHN to 540 BHN
3. Ease of Processing compared to conventional 500 BHN steels
4. Can be Welded with Low Hydrogen Rod providing a major cost saving
5. No pre or post heating required for welding
MICRO STRUCTURE
- SUPERIOR WEAR ABILITY
- SUPERIOR WORK-HARDENING
- SUPERIOR WORK ABILITY
- SUPERIOR WELD ABILITY
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 HARDOX 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 provides elasticity effect which limits gouging, tearing and shearing. Limited amount of “Unstable or Retained Austenite” reduces chipping and cracking.
HARDOX 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.

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.
PROCESSING
| BENDING | WELDING | MACHINING | |
| ENDURA | Radius = 5 times Thickness | No pre or post heating required up to 2″ | Possible with High Speed tools |
| HARDOX | Radius = 7 times Thickness | Pre and post heating required on ALL thickness | Tungsten carbide tools only |
Bending radius can be reduced by bending at right angles to the grain or direction of rolling
