Edit : So I probably should have been more specific . Im looking for a big cooking pot , not one of those factory mixing tanks lol. I guess something that is about the size of about 100 Litres

Someone here suggested I speak to a black smith about it an I honestly have no Idea how to even begin contacting blacksmiths in toronto. If you can let me know then please do. I do have a couple things Im willing to pay to have welded , this pot included. But my biggest questions to the blacksmith would be:

1. 'How do I determine the 'quality' of the steel thst is being used? What the hell is 'steel quality' anyways? can it be quantified or is it qualitatively determined or both?

2. I am looking for steel that could almost last me a lifetime so any ideas as to what I should evem begin to research about when it comes to steel like this? ?

3. ' Im looking for steel that is resistant to water and hot water for the pot that I need welded and then I am looking for steel that is resitant to sweat and external forces (both horizontal and vertical) for this pull up station I need welded where can I research what types of steels I need for these two types of products?
