Stainless Steel Alloy 314 | Stainless Steel Alloy 1.4841 | Super Austenitic Alloy | Seamless Tubes Stainless Steel Alloy | Stainless Steel 314 Alloy Manufacturers
Kanakratna steelage is a renowned exporter, manufacturer, stockist, supplier, and stockholder of high-quality Stainless Steel Alloy Seamless Tubes. These tubes are celebrated for their excellent corrosion resistance, durability, and high strength, making them ideal for a wide range of applications including petrochemical, pharmaceutical, food processing, and marine industries. Stainless steel alloy tubes maintain their integrity and performance across various temperature ranges and environments, offering superior weldability and ease of fabrication. This ensures reliable and long-lasting performance in even the most challenging conditions.
Stainless steel grade 314 has excellent high-temperature resistance characteristics among the chromium-nickel steels series. The silicon content in this material improves oxidation and carburization resistance; however, it can become very brittle when subjected to prolonged temperatures of 649-816°C (1200- 1500°F).
