Kyaw Stainless is a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, known for its top-notch Stainless Steel 310 Fasteners. These fasteners are designed to excel in high-temperature and corrosive settings, boasting impressive durability, strength, and resistance to oxidation. At Kyaw Stainless, every fastener is crafted with precision and adheres to strict quality standards, ensuring that customers receive reliable products with a long lifespan. Stainless Steel 310 Fasteners find their place in various industries, including petrochemical, power generation, and furnace construction, where exceptional mechanical stability and corrosion resistance are crucial for lasting performance.
These fasteners are made up of about 24–26% chromium, 19–22% nickel, along with small amounts of carbon, manganese, and silicon, with iron making up the rest. The high levels of chromium and nickel provide them with remarkable resistance to oxidation, sulfidation, and scaling, even at high temperatures. They have a tensile strength of around 515 MPa and a yield strength of about 205 MPa, along with good elongation and ductility. These characteristics make SS 310 Fasteners perfect for tough applications that require both heat and corrosion resistance.
