Kyaw Stainless is a trusted manufacturer and supplier located in Naypyidaw, Myanmar, specializing in top-notch Stainless Steel 304H Bars. These bars are crafted to provide exceptional strength, resist corrosion, and perform well under high temperatures. Using cutting-edge production methods, each bar goes through rigorous quality checks to guarantee precise dimensions and long-lasting durability. Kyaw Stainless’s Stainless Steel 304H Bars are perfect for tough industrial applications that involve heat and pressure. Thanks to their higher carbon content, these bars boast improved tensile and creep strength, making them a great fit for sectors like petrochemical, power generation, chemical processing, and marine engineering.
These Stainless Steel 304H Bars typically contain around 18–20% chromium, 8–11% nickel, and a carbon content ranging from 0.04–0.10%. They also include trace amounts of manganese, silicon, phosphorus, and sulfur, with iron making up the rest. The elevated carbon content enhances their mechanical strength and oxidation resistance at high temperatures. With a tensile strength of about 515 MPa and a yield strength of around 205 MPa, these bars also offer excellent toughness, weldability, and ductility, even in high-stress situations.
