2019 Mazda MAZDA3 Uses Industry First Steel
I-CAR · January 31, 2019 · Mazda
Summary
The redesigned 2019 Mazda3 features a significant increase in ultra-high-strength steel, with 30% of the body structure rated over 980 MPa compared to just 3% in the previous generation. Notably, it introduces the industry's first 1,310 MPa cold-formed steel, which replaces 1,180 MPa as the highest strength cold-stamped steel used in production.
What to do on the job
Verify the specific steel grades and repairability guidelines for the 2019 Mazda3, paying close attention to the 1,310 MPa cold-formed steel components which have strict heat and sectioning limitations.
How to use it
Use this document to justify the need for specialized ultra-high-strength steel (UHSS) repair procedures and tooling when writing estimates for the 2019 Mazda3. Because 30% of the vehicle structure is now over 980 MPa (including the industry-first 1,310 MPa cold-formed steel), standard pulling, heating, and sectioning methods are prohibited. Refer to Mazda's official body construction guidelines to defend the replacement of these high-strength structural components rather than attempting repairs.
