Is this why car alloy chrome wheels have a higher tendency of cracking vs non chromed alloy wheels? I’ve also noticed that when they crack they usually look like they have been pulled apart as opposed to a clean straight crack like those that happen in OEM non-chrome alloy wheels.
Hi there! The cracking of alloy-typically aluminum alloy-wheels is not due to hydrogen embrittlement. The difference in crack appearance between aluminum alloy vs. steel alloy wheels is due to ductility. The more ductile nature of steel would provide for a fracture that looks more torn than that of less ductile aluminum alloy. Cracks in wheels are typically due to impact fracture, or causes other than hydrogen induced cracking. Hope that helps! - Randy
@@jeffries848 The chrome plating may crack, but there should not be a difference in cracking with the same base metal. I’m not an expert on wheels, so maybe the best option is to investigate if there’s a difference in base metal between chrome plated and non-plated aluminum alloy wheels. Corrosion may also be worth investigating, including galvanic corrosion. Hope that helps! - Randy
@@WurthIndustryNA Aren't aluminium alloys (generally speaking) more ductile than steel alloys? Thus leading to aluminium alloy wheels displaying a more ductile, "torn" fracture than steel ones. Great video series btw, hugely informative!
Hi there! There are two primary aspects to consider. First is the material’s permeability, and second is the elastic or ductile nature of the material to accept internal stresses. When working with different materials, consider these two factors when concerned about hydrogen assisted cracking. It may take some testing to prove your theory on a particular product. Hope that helps! - Randy

You truly covered this well. I am glad to see this type of communication being done for this critical failure mode. Great job guys!
Thank you, Tony, we appreciate it!
Such an important topic of conversation, thank you guys, great information and explanation of how this happens.
Thank you, Michael!

@@WurthIndustryNA Thanks for the reply! Any thoughts as to why chromed aluminum wheels would be more crack prone than non-chromed aluminum wheels?

Can hydrogen penetrate glass like it does metal ?
Are there any materials in which embrittlement does not occur ?

Is this a reason why some screws can’t come in stainless steel as they burst due to hydrogen embrittlement
