For maximum Service Life and flexibility of application, an alloy plate product must offer an ideal ratio of toughness / hardness yet remain a satisfactory degree of formability and ease of field welding. Tri-Braze® is produced by carefully controlled heat treated processes to provide the requirements of this ratio demand.
Tri-Braze® Engineering Data
Hardenability: Tri-Braze® possesses excellent hardenability for depth of hardness. A typical Jominy end quench hardenability shown below illustrates this unique characteristic.
From the Jominy end quench hardenability curve, it can be seen that Tri-Braze® is essentially martensitic at the 10-16 inch position, the cooling rate of which corresponds to the cooling rate in the center of a 2-1/2 inch plate.
Tri-Braze® is designed to have a softer core in very heavy sections to maintain good ductility and provide improved notch sensitivity which is lacking in many thick, hard materials.
Tensile Strength & Hardness:
| Brinell Hardness* |
418/ 512 BHN |
| Yield Strength |
192,000 / 240,000 psi |
| Tensile Strength |
215,000 / 267,000 psi |
| Elongation |
12/20 % |
| Reduction of Area |
40/60 % |
*Although 418 BHN is the minimum hardness obtained with Tri-Braze®, 444 BHN is the "aim to" hardness level and most plates will be 444 BHN minimum.
Elevated Temperature Strength:
Tri-Braze® is a quenched and tempered steel. While all steels tend to lose strength when used at elevated temperatures, creep, stress-rupture and elevated temperature tests have shown that Tri-Braze® maintains good strength at temperatures approaching 1000 °F. Because Tri-Braze® is tempered at 400 °F, heating it above this temperature will cause a decrease in hardness and strength but the lowering of these properties will be very gradual.
