Complete Stud Welding NBT weld studs are available in mild steel and stainless steel materials.


NBT studs are used to secure refractory material and to provide heat dissipation in coal burning boilers. BT studs are commonly made in 430 stainless steel. This stainless typically provides longer stud life than mild steel and is more cost effective than stainless grades 302 and 304.

NBT studs are available in Auto Feed (AF) quality. Please indicate if AF quality is needed.

The “F” ferrules are preferred for welding to flat surfaces. The “C” ferrules are preferred for welding to boiler tubes (i.e. round surfaces).

For application, dimensional and in stock assistance, please contact your Complete Stud Welding representative.
