Kyaw Stainless is a prominent manufacturer and supplier located in Naypyidaw, Myanmar, with a focus on high-quality Stainless Steel 440C Coils. These coils are celebrated for their remarkable hardness, strength, and resistance to corrosion, making them perfect for demanding industrial and engineering applications. At Kyaw Stainless, precision is key; they utilize advanced equipment and adhere to strict quality standards to ensure their products are durable and dimensionally accurate. The company’s Stainless Steel 440C Coils are well-regarded for their outstanding wear resistance and reliable performance in tough environments that require both durability and longevity.
The composition of Stainless Steel 440C Coils primarily includes iron, 16–18% chromium, 0.95–1.20% carbon, along with trace amounts of manganese, silicon, and molybdenum. This high-carbon martensitic structure provides the alloy with exceptional hardness and moderate corrosion resistance. After heat treatment, these coils boast a tensile strength of about 760 MPa and a yield strength of around 450 MPa. They are known for their excellent wear resistance, high mechanical strength, and good dimensional stability, making them ideal for applications that involve friction and mechanical stress.
