Question about Campbell soup cans' steel alloy

I am not asking anyone to do my homework for me, but I am having trouble finding where I could even find this information, and I would really appreciate it if someone could point me in a possible direction.

I have homework for my Materials and Manufacturing class due on Friday that consists of this:

I have found or can find the answers for questions 1, 3, and 4, but I don’t know about 2. Our book isn’t exactly helpful for this specific question, and when I try to google it, I mainly find pages about Warhol’s soup cans or metal manufacturing companies that don’t help.

If anyone knows of a website or resource that might help me I’d really appreciate it.

How about the MSDS for a likely material?

Sounds like you got trapped by looking for “soup” when “food” may have been a better search term.

Thanks gotpasswords! I think that could really help.

Two sources:

ASTM Standard A 623M, Standard Specification for Tin Mill Products, General requirements [Metric]. Standard A 623 without an “M” is the non-metric version of the same standard.

Basically, canning steel is a mild steel, with less than 0.13% carbon, about 0.60% manganese and everything else kept to a minimum. It’s sometimes referred to as “blackplate”. Some canning steel grades are Type D, Type L, and Type MR. Might have some luck with Google!
