Dhruv Metals, based in Hyderabad, India, has earned a solid reputation as a reliable manufacturer and supplier of top-quality Stainless Steel 347H Forgings, specifically crafted for high-temperature and corrosive settings. This type of stainless steel is a stabilized austenitic alloy that features a higher carbon content along with niobium (also known as columbium) to effectively combat intergranular corrosion and boost strength when exposed to heat and pressure. Dhruv Metals prides itself on delivering precision-forged SS 347H components to industries that demand durable, heat-resistant, and weldable materials, ensuring consistent quality and performance for critical applications both locally and globally.
The composition of Stainless Steel 347H Forgings includes chromium (17.0–19.0%), nickel (9.0–13.0%), carbon (0.04–0.10%), niobium (at least ten times the carbon content), manganese (≤2.0%), silicon (≤1.0%), phosphorus (≤0.045%), and sulfur (≤0.030%). These forgings boast a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, an elongation of 40%, and a maximum Brinell hardness of 201 HB. Their carefully balanced chemistry prevents carbide precipitation during welding, which helps maintain structural stability and resistance to high-temperature creep and oxidation.

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 are particularly well-suited for high-temperature applications across various industries, including petrochemical, power generation, oil and gas, and chemical processing. You’ll often find them in heat exchangers, pressure vessels, furnace components, superheaters, boiler tubes, and welded piping systems that face elevated temperatures. These forgings excel under thermal cycling and extended heat exposure, making them a go-to choice for heavy-duty components. Their outstanding resistance to intergranular corrosion post-welding and their ability to maintain mechanical integrity under stress make them incredibly dependable for critical, high-pressure environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
