Emilio Stainless is a reputable manufacturer and supplier located in Manila, Philippines, specializing in high-quality Stainless Steel 347 Pipes. These pipes are celebrated for their outstanding corrosion resistance, heat stability, and mechanical strength. Designed to perform reliably in high-temperature and moderately corrosive environments, Emilio Stainless is committed to upholding international quality standards through advanced manufacturing techniques and rigorous testing. The Stainless Steel 347 Pipes offer remarkable durability, weldability, and oxidation resistance, making them a top choice for industrial applications that demand long-lasting performance and structural integrity in tough conditions.
The composition of Stainless Steel 347 Pipes primarily includes iron, chromium (17–19%), nickel (9–13%), and columbium (niobium) to prevent intergranular corrosion. This ferritic-austenitic stainless steel grade boasts impressive mechanical strength, with a tensile strength of about 515 MPa, yield strength around 205 MPa, and an elongation of 40%. It excels in resisting scaling and oxidation at temperatures up to 870°C, while the addition of niobium enhances stability during welding and exposure to high temperatures, minimizing the risk of carbide precipitation and intergranular corrosion.
