Bare corrosion resisting chromium-nickel welding rod for welding of similar steels of 24% Cr, 13% Ni types. The alloy is also used for welding of buffer layers on CMn steels and welding of dissimilar joints. When using the wire for buffer layers and dissimilar joints it is necessary to control the dilution of the weld. OK Tigrod 309L has a good general corrosion resistance. When used for joining dissimilar materials the corrosion resistance is of secondary importance.

‍

FCAW wire for 22%Cr - 12%Ni stainless steel For flat and horizontal position welding. Developed to be used when welding most mild or carbon steels to type 304. The higher percentages of Cr and Ni provide the necessary crack resistance. Carbon content 0.04% maximum.

A metal cored wire alloyed with 17%Cr and 1% Mo used with M21 shielding gas.

‍

Bare corrosion resisting chromium-nickel rods. OK Tigrod 308L has a good general corrosion resistance. The alloy has a low carbon content which makes this alloy particularly recommended were there is a risc of intergranular corrosion. The alloy is widely used in the chemical and food processing industries as well as for pipes, tubes and boilers. For joining of stainless steels of 18% Cr - 8% Ni-type with low carbon content and Nb-stabilized steels of the same type if the service temperature will not exceed 350°C. Can also be used for welding of Cr-steels except in sulphur rich environments.

Bare corrosion resisting chromium-nickel rods for welding of austenitic chromium nickel alloys of 18% Cr 8% Ni-type. OK Tigrod 308LSi has a good general corrosion resistance. The alloy has a low carbon content which makes this alloy particularly recommended were there is a risk of intergranular corrosion. The higher silicon content improves the welding properties, such as wetting. The alloy is widely used in the chemical and food processing industries as well as for pipes, tubes and boilers.

Exaton SX is a high silicon containing austenitic stainless steel wire for joining grades, such as UNS S32615 (e.g. Alleima® SX). The wire is developed for use in concentrated sulfuric acid and in high concentrated nitric acid. Exaton SX GTAW is used for joining and overlay welding.

‍

A continous solid corrosion resisting chromium-nickel-manganese wire for welding of austenitic stainless alloys of 18% Cr, 8% Ni, 7% Mn types. OK Autrod 16.95 has a general corrosion resistance similar to that of the corresponding parent metal. The higher silicon content improves the welding properties, such as wetting. The product is a modified variant of ER307, basically with a higher Mn content to make the weld metal less sensitive to hot cracking. When used for joining dissimilar materials the corrosion resistance is of secondary importance. The alloy is used in a wide range of applications across the industry such as joining of austenitic, manganese, work hardenable steels as well as armourplate and heat resistant steels.

OK Autrod 347Si is an austenitic stainless steel filler material for welding of stainless steel alloys of 18Cr/8Ni/Nb and 18Cr/8Ni/Ti types where good general corrosion resistance is required. The alloy is stabilized with Niobium to improve the resistance against intergranular corrosion of the weld metal. The higher silicon content improves the welding properties, such as wetting. Due to the niobium content the alloy is recommended for use at higher temperatures.

‍

Bare corrosion resisting chromium-nickel welding rod for welding of heat resistant austenitic steels of the 25Cr-20Ni-type. The wire has a high Cr content and gives good oxidation resistance at high temperatures. Common applications are industrial furnaces and boiler parts as well as heat exchangers.
