Our fasteners are designed for outstanding durability, high-temperature oxidation resistance, and exceptional corrosion resistance. With a strong commitment to precision manufacturing and adherence to international quality standards, Kyaw Stainless guarantees that each product provides long-lasting performance and reliability. Whether it’s for heavy engineering, petrochemical, or power generation industries, our Stainless Steel 348 Fasteners stand out for their unmatched strength and stability, making them the go-to choice for challenging industrial settings throughout Myanmar and beyond.
Stainless Steel 348 Fasteners are primarily made up of chromium (17–19%), nickel (9–13%), and columbium/tantalum, which enhances their stability against carbide precipitation. This unique composition offers remarkable resistance to intergranular corrosion and oxidation, even at high temperatures. On the mechanical side, they boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. This alloy maintains its strength and ductility even under extreme thermal conditions, making it perfect for applications that require both high mechanical integrity and corrosion resistance in elevated-temperature environments.
