DESCRIPTION
VSS-310 is a lime-titania type stainless steel electrode which may form the deposited metal of 25% Cr-20%Ni stainless steel with perfect structure of austenite. The deposited metal has excellent corrosion resistibility and heat resistibility, and shows distinguished ductility because the Ni alloy contents are higher than that of 309 type. It is suitable for welding the steel of high hardenability such as 13% Cr steel, Cr-Mo steel etc., which is difficult to preheating or postheating. Peeling-off of the slag is very good.
APPLICATIONS
Welding of steel corresponding to AISI310S.
INSTRUCTION FOR WELDING
(1) The weld metal is sensitive to hot cracking, because high Cr and Ni alloy contents will be the perfect structure of austenite. Therefore, select the lower welding current stated in the table below.
(2) Keep interpass temperature less 150ºC and do not weld continuously.
