SS 321 Round Bar — Overview

As a specialty stainless steel round bar exporter in India, JPS Metal & Alloys stocks SS 321 ex-Mumbai for both domestic supply and export via Nhava Sheva (JNPT). Titanium stabilization prevents intergranular corrosion after prolonged exposure in the 425–900°C sensitization range, where standard 304/316 would be at risk.
