Emilio Stainless is a trusted manufacturer and supplier of Stainless Steel 347H Bars, proudly based in Manila, Philippines. With a strong commitment to quality and durability, the company specializes in providing high-temperature, corrosion-resistant bars that are essential for critical industrial applications. Emilio Stainless caters to a diverse array of sectors, including power generation, petrochemical, oil and gas, and chemical processing. Renowned for its precision manufacturing, timely deliveries, and competitive pricing, Emilio Stainless has established itself as a reliable source for Stainless Steel 347H Bars not just in the Philippines, but throughout Southeast Asia.
The Stainless Steel 347H Bars produced by Emilio Stainless are crafted from high-carbon, niobium-stabilized austenitic stainless steel. This alloy typically features 17–19% chromium, 9–13% nickel, and niobium (columbium) to help prevent intergranular corrosion during welding and extended exposure to high temperatures. With a tensile strength of approximately 515 MPa and a yield strength of around 205 MPa, these bars deliver outstanding creep resistance, thermal stability, and oxidation resistance. The higher carbon content in 347H boosts its strength and performance in high-pressure, high-temperature settings.
