SS 420 Elbows

The SS 420 Elbow is a vital forging component used in piping systems to change the direction of fluid flow, typically by 45 or 90 degrees. Manufactured from Martensitic Stainless Steel Grade 420, these elbows are specifically chosen for environments demanding superior hardness and resistance to abrasive wear and erosion, areas where standard stainless steel might fail. The material is heat-treatable, offering enhanced mechanical strength. Zeron Fasteners produces these fittings through controlled forging processes, ensuring a highly uniform grain structure that resists stress concentration and fatigue. SS 420 Elbows are widely deployed in the handling of abrasive slurries, high-pressure lines, and in the petrochemical and pulp and paper industries where durability and structural integrity are paramount.
