General Description

AS P-347 is a low carbon rutile coated electrode. It gives a niobium stabilized, Cr-Ni type filler metal of AISI 304 or similar quality.
It has an excellent strength especially in oxidizing environments like nitric acid. Smooth weld beads are highly resistant to acids and to intergranular corrosion at operating temperatures up to 350°C.

Applications and Materials to be Welded

AS P-347 can be used particularly in the welding of austenitic stainless steels of AISI 321 and 347 type. It can also be used for Cr-Ni steels and for steel cast parts having same or similar analysis results with the electrode. Tanks and vessels that are used in chemical and food industries; parts  exposing to the effects of acid, gas and vapor; and water fittings are among some application areas. AS P-308 L can be used for 18% Cr - 8% Ni, Nb stabilized steel parts that are working under low operating temperatures.
