Weldable 321 Stainless Steel Hex Bars
 |
One of the easiest stainless steels to weld, 321 is alloyed with titanium to prevent cracking. The titanium also helps these bars resist corrosion around weld points, making them ideal for finished components such as pipe fittings, valve bodies, and high-temperature assemblies. Their hexagonal shape allows for efficient torque transmission and smooth wrenching for precision fastening. Made to ASTM A484 specifications to fit standard hex sockets and tools, these bars make parts that are easy to grab and tighten. They maintain strength and resist oxidation at temperatures up to 1500° F.

Stainless Steel Foil
 |
321 Stainless Steel—Alloyed with titanium, 321 stainless steel is especially easy to weld and keeps its corrosion resistance around weld points. This material maintains its corrosion resistance and strength in temperatures up to 1500° F. This foil is often used as a heat-treating wrap in temperatures up to 2000° F. It comes with a crimping tool.
