Mellow Stainless Steel is proud to introduce our cutting-edge high-nitrogen austenitic stainless steel solutions, perfectly engineered to meet the demanding requirements of next-generation cryogenic hydrogen infrastructure. As a pioneer in advanced stainless steel technologies, we've developed proprietary nitrogen alloying techniques that deliver unparalleled performance in extreme low-temperature environments.
Our research team has successfully overcome the traditional limitations of stainless steel in cryogenic applications through innovative nitrogen stabilization methods. The Mellow Stainless Steel high-nitrogen series achieves yield strengths exceeding 740MPa while maintaining exceptional toughness at temperatures as low as -269°C – critical for hydrogen storage and transportation systems.
What sets Mellow Stainless Steel apart is our patented manufacturing process that enables nitrogen content up to 1% while maintaining perfect austenitic structure stability. This breakthrough allows our materials to offer:
• 50% higher strength than conventional 316L stainless steel
• Near-zero magnetic permeability (μr < 1.02)
• Superior resistance to hydrogen embrittlement
• Excellent weldability without post-weld heat treatment
The economic advantages are equally impressive. By replacing expensive nickel with atmospheric nitrogen, Mellow Stainless Steel achieves 30-40% cost reduction in raw materials while delivering better performance. Our cryogenic-grade stainless steels are already being adopted by leading hydrogen energy projects across Asia and Europe, demonstrating our global technical leadership.
For engineers designing liquid hydrogen storage tanks, transport vessels, or fueling station components, Mellow Stainless Steel provides certified material solutions with full traceability and comprehensive technical support.
