DId you guys realize that at approx 1700*F mild or alloy steel is not magnetic?

loyalty to the American people."

Were you taking it out of your oven with a magnet and dropped it on your toe?


Something tells me there is a story behind this random fact. ;D

Yep,there is. When steel hits non magnetic it is capable of absorbing carbon. Case hardening. It is also the point of thru hardening higher carbon content steels.

316 l or sometimes 316 lo means low oxygen and is more corrosion resistant than 316 

most 316 castings are magnetic   when they come out of the sand because they cooled to slowly , then you heat treat them , non magnetic again

Thanks, I learned somthing new myself!

What I was refereing to, because I see it more, is materials like12L14 (mild steel) where the L is within the grade number and does mean leaded stock. I have Stainless with the L after it and always avoided using it in welding applications. Now I know different. It is easier to cut though which was my inital statment.

316L or 316LO means low oxegen and slitely is more corrosion restant than plan 316 as it requires a lower amount of oxygen to mantaine its resitance
