Interpass temperature: Max. 150°C. Heat input: Max. 2.0 kJ/mm. Heat treatment: Generally none. For constructions that include low-alloy steels in mixed joints, a stress-relieving annealing stage may be advisable. However, this type of alloy may be susceptible to embrittlement-inducing precipitation in the temperature range 550 – 950°C. Always consult the supplier of the parent metal or seek other expert advice to ensure that the correct heat treatment process is carried out. Structure: Austenite with 5 – 10% ferrite. Scaling temperature: Approx. 1000°C (air). Corrosion resistance: Primarily designed for high temperature applications with service temperatures up to 1000°C. The resistance to intercrystalline corrosion is somewhat limited due to the high carbon content.

Power supply unit on a piece of equipment failed. The unit is no longer produced and there was no reconditioned units available. OKmarts provided a replacement unit for far less than the original cost. It went right in the electrical cabinet and works perfectly.
