HC400/690TR common cold rolled TRIP steel microstructure: ferrite, bainite and retained austenite, wherein the content of retained austenite is between 7% and 15%.

TRIP steels have good formability, and the formability is mainly derived from retained austenite within the structure.

HD950/1300HS hot drawing PH or B steel microstructure: Ferrite and pearlite (before heat treatment), martensite (after heat treatment).

HC950/1300HS hot drawing PH or B steel performance features: ultra high strength (tensile strength up to 1500MPa above.

BR1200HS hot drawing PH or B steel microstructure: Ferrite and pearlite (before heat treatment), martensite (after heat treatment).

B1200HS hot drawing PH or B steel microstructure: Ferrite and pearlite (before heat treatment), martensite (after heat treatment).
