So !
Is that embrittlement ,such a bad thing , on the ( inner )straight piece of the front leg , made of ' cheap mild-steel ' . It seems a good thing to stiffen that piece of pipe up . A bit, instead of it being bendy. As well as "wear proofing " it a lot .
It's all made up, so cannot put a better ( tenstile ) part in , then weld it to the forks .
I have not made enquiries as to the pricing of said plating, ( for half the pipe length ). It could be out of my ' pensioner ' pocket money .
