Kolkata, India-based Neil Metals is a well-established producer and provider of **Stainless Steel 304 Forgings**, offering high-precision, hot-worked parts that comply with international standards like ASTM A182 and EN 10204. Employing controlled forging in the range of 927–1260 °C, their technique improves grain structure for increased strength, durability, and resistance to corrosion. Supplying industries such as chemical, food processing, petrochemical, power generation, and marine, Neil Metals integrates strict quality control, competitive pricing, and reliable delivery to guarantee high-performance forged components for severe applications.
**304 Stainless Steel Forgings** are made up of 18–20% chromium, 8–10.5% nickel, with 0.08% carbon as the maximum, and add manganese, silicon, phosphorus, and sulfur according to ASTM/EN standards ([steelpipesfactory.com][1]). Mechanically, they provide a tensile strength of at least 515 MPa, yield strength of about 205 MPa, and elongation of 35–40% ([steelpipesfactory.com][1]). Forging provides better grain flow, which increases impact toughness and resistance to fatigue, while maintaining superior corrosion properties and the ability for intermittent service up to \\~925 °C.

304 Stainless Steel Forgings have extensive applications in **valve bodies, pump casings, heat exchanger parts, and shafts**, enjoying the advantages of high strength, corrosion resistance, and accurate shape ([walkson.com][2]). In **chemical, petrochemical, pharmaceutical, and food processing industries**, they provide hygienic operation and acid, alkali, and cleaning chemical resistance. In addition, they are used in **power generation, marine, and offshore applications**—including boiler components, marine bolts, and structural elements—where performance in corrosive, wet, or salty conditions is vital .
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
