CEWELD® 4015 HL-Kb is used for joining and cladding 17% chromium alloys and cladding components where heat and corrosion resistance is required. Areas of application are sealing surfaces on gas, water and steam fittings.
CEWELD® 4015 HL-Kb is used for joining and cladding 17% chromium alloys and cladding components where heat and corrosion resistance is required. Areas of application are sealing surfaces on gas, water and steam fittings.
CEWELD® 4015 HL-Kb can withstand working temperatures of up to 450°C and offers scaling resistance up to 950°C. Preheating at 250 °C and stress relieving at 800 °C is recommended if this is permissible for the base metal. In the machined state there should be at least two weld layers on top of each other. The weld metal can be polished and is scale-resistant up to 900°C. The achievable hardness of the weld metal is mainly influenced by the dilution with the respective base material and its chemical composition. The higher the dilution and the C content of the base material, the higher the hardness of the weld metal. The preheat and interpass temperature should be 200 – 300ºC. A tempering 730 – 800ºC is possible.
