Ultra-high strength steel is a type of advanced metallic material. It features high strength, high toughness and good fatigue resistance. Generally, its yield strength is greater than 1380 MPa. Ultra-high strength is achieved through processes such as alloying and special heat treatment. It is widely used in fields with high requirements for material strength and lightweight, including aerospace, national defense and the automotive industry.

Product features: High strength, high toughness, good fatigue resistance, relatively good corrosion resistance, excellent workability, and good weldability.
