​Mazda Uses 1300 MPa (190 ksi) Cold Stamped Steel

​The 2019 Mazda 3 uses 1300 MPa (190,000 psi) steel for the front pillar and roof rail inners; the hinge pillar, roof rail, and side sill inner reinforcements, and the No. 2 crossmember. This cold-stampable steel was jointly developed by NSSMC (Nippon-Sumitomo) and JFE Steel, and will be used throughout Mazda’s lineup. Joining and repair techniques need to be adjusted to account for this ultra high strength achieved by an engineered microstructure.​

​​Details from Mazda are in their Press Release.
Details on the crash load path and expanding AHSS use at Mazda are shown at Repairer Driven News.
