Neil Metals, located in Kolkata, India, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Stainless Steel 347H Forgings, serving a variety of industrial sectors both locally and globally. Renowned for their precision engineering, prompt delivery, and high-quality materials, Neil Metals produces forgings that boast impressive strength, heat resistance, and corrosion resistance. Utilizing advanced technology and rigorous quality control measures, their Stainless Steel 347H Forgings are perfectly suited for high-temperature applications and pressure systems. With a robust distribution network and a focus on customer satisfaction, Neil Metals guarantees dependable and effective forging solutions for clients facing demanding challenges.
The composition of Stainless Steel 347H Forgings primarily includes iron, chromium (17-19%), and nickel (9-13%), with the addition of columbium (niobium) to enhance stability against intergranular corrosion. The carbon content, ranging from 0.04% to 0.10%, contributes to its high-temperature strength. Other trace elements like manganese, silicon, phosphorus, and sulfur are also present. These forgings exhibit a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 35%. This alloy is known for its excellent creep resistance, oxidation resistance, and durability in high-temperature settings, making it ideal for pressure and high-stress industrial applications.

Yes, Stainless Steel 347H forgings can be used for potable water applications, offering excellent corrosion resistance and durability, particularly in high-temperature systems or environments with varying water quality.
Yes, Stainless Steel 347H forgings are highly suitable for high-temperature applications due to their niobium stabilization, which enhances resistance to oxidation, thermal stress, and intergranular corrosion at elevated temperatures.
Stainless Steel 347H Forgings find extensive use in industries that demand performance in extreme temperatures and corrosive conditions. They are frequently utilized in heat exchangers, superheaters, boiler tubes, furnace components, and exhaust systems. In petrochemical and chemical processing facilities, these forgings ensure structural integrity and reliability when faced with thermal cycling and chemical exposure. Power generation plants and refineries also depend on 347H forgings for their resistance to intergranular corrosion and mechanical stress. Their long service life and ability to maintain strength at elevated temperatures make them a preferred choice in challenging environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
