I warped a Matfer Bourgeat carbon steel pan on my fathers induction stovetop 4-5 years ago.
De Buyer Mineral B pans solved the issue. No warping with them so far 4+ years of use.
I do own a Matfer Bourgeat carbon steel pan in 22 cm in my own collection, but I cook on gas and a very little 22 cm Matfer only has an effective cooking area of 12-13 cm, so it’s not likely to warp on any cooking surface.
I think the new Matfer carbon steel pan is a definite upgrade design wise to the old design, but let’s see how well it performs.
