Spring Work

[sussexmuzllodr]

messed around making spring from Hardware Store metal. Kinda got a working spring but way too soft. Used all the conventional methods heating hardening and cooling..ect. Is it the metal itself? Do you need "Spring Steel" for this purpose. I dont know as this is the first time Ive tried doing this. I need someone with experience in this that has the metallurgy knowledge. I ordered spring stock from dixie and will give it another go. Like I said I produced a spring but it was not quite there. I had always thought springs and such were just basically made from metal stock. I know some of you on here are really good on this subject.....I need further edumacation on it....thanks in advance.

Not any steel makes a spring, it must have enough carbon in it to harden. Common steel stock you might get from a hardware store is mild steel having less then .001% carbon. Spring stock like 1075 has .075% carbon. That’s 3/4 of one precent carbon. No one can harden steel with low carbon no matter how hot it’s heated or what it’s quenched in, the carbon content is the magic. Use the stuff you get from Dixie and follow their directions. It’s science not sorcery.

Thanks that helps out the understanding of it better.
