Mazda CX-5 Service & Repair Manual: Ultra High Tension Steel [Construction]
Characteristics of Ultra High-Tensile Steel Plates
-
Ultra high-tensile steel plates have enhanced tensile strength compared to previous high-tensile steel plates.
-
Because the strength is maintained even though the plates are thin-walled, the ultra high-tensile steel plates are used for the frames and the main frame parts which form the cabin, reducing the weight of the vehicle.
-
Enhanced shock absorption has improved the safety.
Range of Use and Cautions for Service
-
Because the ultra high-tensile steel is hard and it may be difficult to reform, when extracting the damaged part using a frame repair machine, perform the work verifying that other parts are not affected.
-
When drilling welded parts, use a well-ground drill bit.
-
After welding, inspect the weld strength. If adhesion is poor, perform arc welding (plug welding).
