Thermanit X


EN ISO 3581-A E 18 8 Mn B 2 2
AWS A5.4 E307-15 (mod.)
Mat. No. 1.4370





Stainless. Resistant to scaling up to 850 °C (1562 °F). No adequate resistance against sulphureous combustion gases at temperatures above 500 °C (952 °F). For joining and surfacing applications with heat resistant Cr steels/ cast steel grades and heat resistant austenitic steels/ cats steel grades. Well suited to fabricating austentic-ferritic joints - max. service temperature 300 °C (572 °F). For joining unalloyed/ low alloy or Cr steels/ cast steel grades to austenitic steels. Low heat input required in order to avoid brittle martensitic transition zones. Not suitable for the welding of buffer layer, cladded sheet metal or cladding applications.
