Kyaw Stainless is a trusted manufacturer and supplier of Stainless Steel 405 Sheets and Plates based in Naypyidaw, Myanmar. They provide durable and budget-friendly stainless steel products tailored for both industrial and commercial applications. Stainless Steel 405 is a ferritic grade known for its enhanced weldability and resistance to oxidation, especially at high temperatures. Kyaw Stainless offers sheets and plates with precise thickness, a smooth finish, and a long lifespan, making them ideal for fabrication and equipment exposed to heat. Their SS 405 products find extensive use in the automotive, chemical processing, and engineering industries. With cutting-edge production techniques and rigorous quality standards, the company guarantees consistent performance, strength, and dependable corrosion resistance.
Typically, Stainless Steel 405 Sheets and Plates contain 11.5–14.5% chromium, with aluminum added to boost oxidation resistance and scaling protection. This alloy provides moderate corrosion resistance, stable mechanical strength, and good weldability, making it a great choice for applications that experience thermal cycling. SS 405 retains good toughness and structural integrity even at high temperatures, and its ferritic nature enhances its resistance to cracking during welding. The material also offers decent formability and machinability, which simplifies fabrication and installation. While it may not be as corrosion-resistant as 304 or 316 grades, its ability to withstand heat and mechanical durability makes it a valuable option for high-temperature settings.
