Qingtuo Group has unveiled a breakthrough product. Their new “advanced high-strength stainless steel” is making waves in the shipbuilding industry. This innovation is highly relevant for SS pipe manufacturers worldwide.
The material offers exceptional properties. Its strength is over 30% higher than traditional alternatives. A key model achieves a yield strength exceeding 450 MPa. This performance sets a new benchmark for high-end marine materials.
Technical Breakthrough Enables Superior Performance
Qingtuo’s success stems from a revolutionary production process. The company uses China’s first 3500 stainless steel steckel mill. They pioneered a new integrated technology: “wide-plate rolling – online solution treatment – online surface treatment.”
This method is a major breakthrough for wide and thick stainless steel plate production. It ensures the new marine material delivers excellent and stable performance. For SS pipe manufacturers, this means access to more reliable high-strength raw materials.
Material Advantages for Marine Applications
The product series offers compelling benefits beyond sheer strength:
Excellent pitting resistance comparable to or better than traditional stainless steel
Successful inclusion in relevant national standards
Clear path for widespread adoption
These properties make the material ideal for demanding marine environments. It helps shipbuilders reduce structural weight and extend service life.
