What type of steel to choose

[danc1]

Hi,

I would like to know what type of steel you are using to build a smoker. 

Is 44w grade steel safe for a reverse flow vertical smoker ?

Thank you

Use mild steel.....   44W is high tensile strength...  it may not take the expansion and contraction of the heat / no heat cycling..  it may crack and warp...

Unless he anneals it first.

What temperature does it take to anneal high tensile steel ??  I have no idea....

 

[daveomak]

I looked up 4140....   ~1500 deg. and slowly cooled...

I was going to say 1400 but you beat me to it.
