As with most endeavors, the success of fabrication is largely determined well ahead of the act of fabrication. Before the first fastener is ever attached, decisions must be made to ensure their stability and resilience.

At PFSNO, engineers and other manufacturing stakeholders have access to the highest quality stud welds in a variety of shapes and sizes suited to fit the needs of industries as diverse as offshore oil drilling and construction. Our arc weld studs are manufactured from materials that meet codes and specs established by the AWS, ANSI, ASTM, and other respected industry associations.

AISI 1006 low-carbon steel

AISI 1006 low-carbon steel contains by weight .05% to .30% carbon. A soft, ductile alloy, this mild steel is ideal for use in projects that require bending and welding. One of the easiest metals to weld, low-carbon steel is also relatively inexpensive.

AISI 1020 low-carbon steel

With a higher carbon ration than AISI 1006, AISI 1020 low-carbon steel’s increased carbon content translates to increased hardness and strength; however, the trade-off is a loss of ductility. With a higher-carbon steel, preheat must be used to prevent cracking in heat-affected zones. Like other low-carbon steels, AISI 1020 is economical and easily welded.

300 series stainless steel

With a chemical composition of 18% chromium and 8% nickel, 300 series stainless steel is the most corrosion-resistant, ductile, and weldable type of stainless steel. Carbon steels are unprotected from air and moisture, which leads to prolific rusting. Stainless steels, on the other hand, are protected from corrosion-causing oxygen diffusion by a passive layer of chromium oxide. Stainless steels are more costly, but they’re necessary in heavy duty fabrication.

5000 series aluminum

With exceptional welding characteristics and high corrosion-resistance, 5000 series aluminum  is ideal for harsh marine environments. Though aluminum is not heat treatable, it can be strengthened by cold working, improving both the tensile and yield strength and reducing crack sensitivity. However, it’s important to bear in mind that too much cold work can result in stress corrosion.
