Features
18Ni300 steel is an ultra-low carbon Fe-Ni alloy, which corresponds to the US grade M300 and the European grade 1.2709. 18Ni300 steel is made of carbon-free or micro-carbon martensite as matrix, and alloy compounds such as Mo, Co, Ti and Al are precipitated in the aging process to form a second phase strengthened ultra-high strength steel. Compared with traditional steel, 18Ni300 steel has excellent weldability, thermoplasticity, workability, and good toughness while having ultra-high strength.
