Overview:

Krystal 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.

304LN stainless steel grade is a nitrogen-strengthened version of 304 stainless steel grade. By without imparting the ductility nitrogen increases the yield strength of austenitic grade. It has properties such as good resistance to intergranular corrosion in welded condition, excellent fabrication properties, low temperature toughness, high strength and excellent ductility. Stainless steel 304LN is an austenitic in the annealed condition (1000°C – 1100°) and rapid cooling in air or water. It contains little amount of ferrite. 304LN is more stable than grade 304L against martensitic transformation induced by deformation at low temperature.
