    Weldable 321 Stainless Steel Rods

    Image of Product. Front orientation. Stainless Steel. Weldable 321 Stainless Steel Rods.
    One of the easiest types of stainless steel to weld. Alloyed with titanium, 321 is unlikely to crack while welding and won't corrode around weld points. It stays strong and corrosion resistant in temperatures as hot as 1500° F.

    Weldable 321 Stainless Steel Hex Bars

    Image of Product. Front orientation. Stainless Steel. 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.
