Kyaw Stainless is a top-notch manufacturer and supplier located in Naypyidaw, Myanmar, specializing in high-quality Stainless Steel 317 Pipes. These pipes are celebrated for their exceptional resistance to corrosion, oxidation, and high-temperature scaling. Stainless Steel 317 is a molybdenum-rich austenitic alloy that provides enhanced strength and corrosion resistance compared to the 316-grade. At Kyaw Stainless, we take pride in producing each pipe with meticulous attention to detail, ensuring they undergo rigorous quality checks for durability, precise dimensions, and outstanding mechanical properties. Our 317 pipes are widely utilized in tough industrial settings where strength, performance, and chemical resistance are crucial.
Stainless Steel 317 Pipes are made up of chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), which greatly improve their resistance to corrosion and pitting. With a tensile strength of about 515 MPa and a yield strength of around 205 MPa, these pipes offer remarkable durability and formability. The elongation rate of 35% ensures they are quite ductile, while the hardness averages 85 HRB. The molybdenum content enhances their resistance to acids like sulfuric and acetic acids, making these pipes perfect for high-stress and corrosive environments across various industrial applications.
