# Closed-die forgings and flanges from India: process and clusters > How closed-die forgings and flanges are made in India, step by step, and where: Pune, Ludhiana and Rajkot. QA tests, HS heading and lead times. Source: https://sourcesquid.co/india-atlas/products/closed-die-forgings-flanges/ Product guide # Closed-die forgings and flanges. From billet cutting to inspection. Closed-die forgings and forged flanges are best sourced from Pune–Chakan, Ludhiana, Rajkot, Faridabad, Hosur, Jamshedpur and Mandi Gobindgarh. Indian forge shops supply crankshafts, gears, yokes, levers, flanges and fittings in carbon, alloy and stainless steel, often heat-treated and machined.

From small parts under a kilogram to heavy forgings of several hundred kilograms, depending on press or hammer capacity. ### Can I get flanges to ASME B16.5 or EN 1092-1? Yes. Many suppliers forge and machine flanges to ASME B16.5 and EN 1092-1 with 3.1 certificates. ### Do Indian forgings come heat-treated? Yes. Most forge shops normalise, or harden and temper, in-house to the hardness you specify. More product guides ## Related products.
