Lastifil 802

Welding of heat resistant steel (AISI 310)

Fully austenitic solid welding wire suitable for welding heat resistant steels with working temperatures up to 1150 °C (2100 °F) (oxidizing atmosphere).

Resistant against thermal shocks, against corrosion and oxidation at high temperatures.

Also suitable for welding heat resistant steel of the C-Cr-Al type, for welding armoured steel and for joining austenitic stainless steel to carbon steel or low-alloyed steel.

Specifications & Usage

Application

Welding heat resistant steel used in heat treatment installations, cement furnaces, process industry.

Wn° 1.4841, 1.4845, 1.4837, 1.4840, X15CrNiSi2520, G-X15CrNi2520

AISI 310, 310S, 309

Afnor Z5CN2520, Z10CN2520, X10CrAl7, X10CrAl24.

Remark: Staying too long at temperatures between 650 °C and 850 °C (1200 - 1560 °F) decreases the toughness of Lastifil 802.
