BARE 308/308H

BARE 308/308H is used for TIG, MIG, and submerged arc welding of unstabilized stainless steels such as Types 301, 302, 304, 305, 308. This filler metal is the most popular grade among stainless steels, used for general purpose applications where corrosion conditions are moderate. The C content in the 0.04-0.08 range provides higher strength at elevated temperatures.

BARE 308/308L

BARE 308/308L is used for TIG, MIG, and submerged arc welding of stainless steels such as Types 304L, 321, and 347. This classification is the same as the BARE 308/308H except that the carbon content is held to a maximum of 0.03% to reduce the possibility of intergranular carbide precipitation. This increases the resistance to intergranular corrosion without the use of stabilizers such as Cb, or Ta.

BARE 308LSi

BARE 308LSi is a stainless steel welding wire for TIG, MIG, and submerged arc welding. This wire is used to weld equipment made with 310, 302, 304, 304L, 305, 308, 308L and 347 stainless grades. This classification is the same as the BARE 308/308L except that the Si% is higher. The welding speed is higher than 308 or 308L due to improved wettability of weld metal.

BARE 309

BARE 309 is used for the welding of similar alloys in wrought or cast form. It is mostly used for welding dissimilar materials such as mild steel to stainless steel, as well as for a barrier layer in stainless overlays. For some applications, welding of straight chromium steels can be accomplished with this consumable.
