Unifit Metalloys Inc. is a prominent distributor of SS 321 / 321H Stud Bolts, which is available in different sizes, shapes and specifications to our patrons. The high alloy level and high ferrite content in Stainless Steel 321 Stud Bolts enables the weld metal to tolerate dilution from carbon and low alloy steels without hot cracking, because this deposited weld metal is of radiographic quality. The deposited weld metal like Stainless Steel 321H Stud Bolts is not as strong in elevated temperatures as the standard or the stabilized alloys. Our goal is to provide an astonishing experience for our products like SS 321 Stud Bolts during every customer interaction.
SS 321H Stud Bolts overlays on mild steel or low alloy steels for joining clad plate, where subsequent layers are deposited with an electrode chosen to match the cladding. Some applications for 321 Stainless Steel Stud Bolts may be substituted with filler metal, but applications generally require molybdenum or contain no molybdenum. Strength of this low-carbon alloys like 321H Stainless Steel Stud Bolts; however, may not be as great at elevated temperatures as that of the columbium (niobium)-stabilized alloys.
Stainless Steel UNS S32100 Stud Bolts have a single phase austenitic structure due to heat treatment during the steel making process, while austenitic stainless steel welding consumables contain ferrite to prevent hot cracking during welding.
