  • The lower the grade the faster it rusts. Forgot most people don’t know that. Its rusting because there is iron in steel (duh). It’s rusting quickly because it has low concentration of rust inhibitors like chromium or nickel. Increasing the concentration of these metals makes it rust slower. It also makes it harder to tool into a car body, making it a shifty choice for a car shell.

    The article you linked is either uninformed or being misleading about “free iron”. That just means there are no rust inhibitors so they are leaving free energy available on the surface of an iron grain at the surface of the material. This makes it rust quickly where those grains are. There are millions of these grains at the surface where the metal interfaces with air. The iron particles are in the body panel, not on top of it.


  • I have an MS in mechanical engineering focused in materials and I wrote a few papers on 3d printing of stainless tool steels. I’ve read further down the thread and you are completely wrong.

    It’s rusting because it’s a low grade stainless. Its low grade because stainless steel work hardens when bent or machined. Lower grades have less issues with work hardening. They made this choice to save on tooling costs I assume.

    Work hardening is when you permanently deform a material it gets more brittle. Stainless is an unbelievably stupid choice for a vehicle body because it needs to be formed into complex shapes which require lots of deformation. It’s why SS cars feature mostly large flat panels and also partially why we have been moving towards aluminum body panels.





  • Mostly agree, I hate Samsung in general (sent from Samsung Galaxy S22). Anytime I see someone considering their appliances or TVs I try to turn them to something else. They have made the best batteries for a long time though. I hope a competitor rises to squish them a bit.

    Don’t buy a sumsung washer. I only buy used washers and dryers because I’m cheap and handy. Samsung is not an option because a large part of the user market is broken in a way that costs the same as buying new.

    I do sort of disagree with your QA comment. Everyone seems to think QA stops once you sell a product, but it doesn’t. They did a full recall to fix their quality mistake. It’d be like if Tesla finally recalled all of the cybertrucks for sucking as much as they do. Massive PR hit to attempt to maintain quality.













  • Yeah I’m old enough to have started with candy bar phones. Battery life has been creeping back below 1 day for a while. That motoG power would play music on Bluetooth all day if I started at 10% battery. It could also sit at 1% battery for hours if I didn’t touch it. Getting this new flagship phone is making me realize I value battery life way more than I realized.

    Biggest issue with the older motoG was the camera sucked. I think the new version fixed that so I’ll probably go back to it.
