Featuring long-radius geometry, this fitting provides smooth directional flow transition while maintaining reduced wall thickness for lightweight fabrication and efficient installation.\u003c\/p\u003e \u003cp\u003eConstructed 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 addition of titanium in 321 stainless stabilizes the alloy at elevated temperatures and reduces the risk of intergranular corrosion and weld decay in heat-affected zones. This makes 321 stainless particularly well suited for thermal cycling, exhaust systems, and industrial applications where sustained heat exposure is expected.\u003c\/p\u003e \u003cp\u003eSchedule 5 wall thickness (approximately 0.065\") provides a lightweight solution appropriate for fabrication projects where structural load and pressure demands are moderate. Ends are factory-beveled for secure and consistent butt-weld installation. Fittings are ink-stamped “Ace Race Parts” for manufacturing identification.\u003c\/p\u003e\n\n\u003cb\u003eFeatures\u003c\/b\u003e\n\n\u003cul\u003e \u003cli\u003eMaterial: 321 stainless steel (titanium-stabilized)\u003c\/li\u003e \u003cli\u003eWall thickness: Schedule 5 (approx. 0.065\")\u003c\/li\u003e \u003cli\u003eGeometry: Long radius 90° elbow\u003c\/li\u003e \u003cli\u003eStandards: ASTM A403\/A960\u003c\/li\u003e \u003cli\u003eDimensions: ASME B16.9\u003c\/li\u003e \u003cli\u003eEnhanced resistance to heat-related corrosion and weld decay\u003c\/li\u003e \u003cli\u003eBeveled ends for consistent butt-weld fit-up\u003c\/li\u003e \u003cli\u003eInk-stamped for manufacturer identification\u003c\/li\u003e \u003c\/ul\u003e\n\n\u003cb\u003eApplications \u0026amp; Compatibility\u003c\/b\u003e\n\n\u003cp\u003eCommonly used in high-temperature industrial piping, exhaust systems, thermal processing lines, and fabricated stainless assemblies requiring improved resistance to heat-affected corrosion.
