1-1/4" Schedule 5 45° Elbow 321 Stainless

1-1/4" Schedule 5 Long Radius 45° Elbow – 321 Stainless Steel

PNW Sanitary 321 stainless steel Schedule 5 long radius 45° elbows are precision-manufactured butt-weld fittings designed for nominal pipe size (NPS) stainless piping systems operating in elevated temperature environments. The long-radius 45-degree geometry provides a smooth directional transition that supports improved flow characteristics while maintaining lightweight construction for efficient fabrication.

Constructed from 321 stainless steel and manufactured in accordance with ASTM A403/A960 material standards and ASME B16.9 dimensional requirements, this elbow is engineered for high-temperature service. The titanium-stabilized composition of 321 stainless enhances resistance to intergranular corrosion and reduces the risk of weld decay in heat-affected zones, making it well suited for applications involving sustained heat exposure or repeated thermal cycling.

Schedule 5 wall thickness (approximately 0.065") offers a lightweight and cost-effective solution for fabrication projects and industrial assemblies where structural load and pressure demands are moderate. Ends are factory-beveled to ensure consistent and secure butt-weld installation. Fittings are ink-stamped “Ace Race Parts” for manufacturing identification.
