MECHANICAL PROPERTIES (RANGE)
Particularly suitable for hardfacing wear-resisting parts subject to sliding impact e.g. Slide ways, shock resistance e.g. cams and rolling impact resistance, e.g. rotors. Typical applications include rails, rail crossings, switch points, sprockets and wearing parts, such as rope pulleys, tumblers, rollers, caterpillar track rollers and links, wheel flanges, stud links and similar components.
For welding of fine grained steels and steels containing approximately 1 % Chromium, 0.5 % Nickel, 0.5% Copper, steels of dissimilar compositions having greater resistance to atmospheric corrosion. Excellent for weathering steels like Corten - A & B Steels, SAILCOR, ETC and of radiographic quality weld.
Keep dry and avoid condensation. Re-drying recommended at 300-3500C/ 2 Hrs. for 5 times max.
