Abstract Microstructures, mechanical properties and corrosion resistance of a new high-strength sorbite stainless steel were analyzed and evaluated, which was designed based on the concept of “hybrid”. Furthermore, the sorbite stainless steel was compared with other typical steels and its application prospects were discussed. Results showed that the microstructure of sorbite stainless steel was similar to that of the martensitic stainless steel. The strength and toughness of the sorbite stainless steel matched well and could be regulated in a wide range. The formability and impact properties were favorable as well. The corrosion resistance of the sorbite stainless steel was comparable to or slightly worse than 201 austenitic stainless steel, while it was slightly better than 410 martensitic stainless steel. Therefore, the application prospects of the sorbite stainless steel is board in the field of corrosion-resist structural engineering.
