JPS Metal & Alloys supplies SS 304 / 304L round bar ex-stock Mumbai to ASTM A276 / A479, UNS S30400 / S30403 — international equivalents, composition, mechanical properties and applications below.
As a specialty stainless steel round bar exporter in India, JPS Metal & Alloys stocks SS 304 / 304L ex-Mumbai for both domestic supply and export via Nhava Sheva (JNPT). 304L is the low-carbon version of 304, used where welding is involved — the lower carbon content avoids carbide precipitation at the weld line.
