Kyaw Stainless is a well-respected manufacturer and supplier based in Naypyidaw, Myanmar, focusing on high-quality Stainless Steel 420 Fasteners. These fasteners are celebrated for their impressive strength, hardness, and resistance to corrosion, making them perfect for the rigorous demands of industrial and mechanical applications. At Kyaw Stainless, they harness cutting-edge technology and top-notch raw materials to create fasteners that promise both durability and precision. Their Stainless Steel 420 Fasteners are particularly suited for environments where toughness, wear resistance, and visual appeal are crucial, making them a dependable choice for both structural and high-performance needs.
The composition of Stainless Steel 420 Fasteners includes iron, 12–14% chromium, and 0.15–0.40% carbon, which gives them their martensitic properties. When heat-treated, these fasteners showcase high tensile strength (around 700–850 MPa) and remarkable hardness. They provide moderate corrosion resistance in mild conditions and perform well against scaling at higher temperatures. The combination of the alloy’s mechanical strength and its ability to achieve a polished finish makes it perfect for applications that require both durability and an attractive look.
