Based in Naypyidaw, Myanmar, Kyaw Stainless is a reputable manufacturer and supplier that specialises in premium stainless steel products made for demanding industrial applications. Stainless Steel 310 Bars, one of its premium products, are well known for their remarkable durability, corrosion resistance, and high-temperature strength. Produced using advanced manufacturing processes and premium-grade raw materials, these bars offer reliable mechanical performance and dimensional accuracy. 310 stainless steel bars are perfect for fabrication, structural elements, and high-temperature applications in sectors like power generation, petrochemical processing, furnaces, and heat exchangers, both domestically and abroad, because Kyaw Stainless guarantees rigorous quality control and accuracy in every product.
Iron, chromium (24–26%), and nickel (19–22%) make up the majority of stainless steel 310 bars, with trace amounts of silicon, manganese, and carbon (0.25%). Excellent oxidation resistance and thermal stability at high temperatures are provided by the high concentration of nickel and chromium. These bars have an elongation of about 35%, a yield strength of 205 MPa, and a tensile strength of at least 515 MPa. In corrosive and high-temperature environments, they resist scaling and retain their mechanical integrity. Because of its special composition, stainless steel 310 is perfect for mechanical and structural parts that are subjected to high temperatures and oxidising environments.
