Tri-Mark TM-B9 welding wire improves weld quality on modified Grade 91 steels used in high temperature, high pressure oil and gas applications.
The gas-shielded flux-cored wire offers all-position welding capabilities. It fully matches base material properties to ensure top weld quality. TM-B9 meets requirements of chrome-moly welding, including provision of an X-factor of less than 15 ppm, says its maker. It also provides a weld deposit with low diffusible content: 3.10 ml per 100g of weld metal to prevent cracking during pre and post-weld heat treat cycles of Grade 91.
