Voestalphine Bohler Q E 8018-B2 H4 Creep Resistant Stick Electrodes

Premium 8018 Stick Electrodes

BÖHLER FOX DCMS kb is a core wire alloyed covered electrode with basic coating for shielded metal arc welding. The 1% Cr / 0.5% Mo type weld metal exhibits a bainitic microstructure with favorable mechanical properties in tempered and quenched and tempered condition. Under certain conditions applications in the as welded condition is possible. The range of application covers joint welding of similar alloyed creep resistant steel and steel casting. BÖHLER FOX DCMS kb is approved for application under creep condition at design temperatures up to 570 ºC. Due to the low content of residual and tramp elements the weld metal offers a typical Bruscato factor < 12 ppm. Thus, being resistant to temper embrittlement and complies with the requirements on step-cooling testing. The optimized coating guarantees low level of diffusible hydrogen in the weld metal and a metal recovery of 115 %

When to use 8018-B2 Instead of 7018:

• High temperature applications that require additional creep resistance
  • Continuous service up to 570°C
• Base metal matching:
  • ASTM Pipe & Tube: A335 Grade P11 / P12, A213 Grade T11 / T12
  • ASTM Forgings & Plate: A182 Grade F11 / F12, A387 Grade 11, A234 Grade WP11
  • Castings: A217 Grade WC6
• Requirement for reduced embrittlement when undergoing step-cooling or long heat cycles
