The industrial ones I believe are made of stainless steel and the portable blue / orange ones like Calors range are made of mild steel coated on the inside and painted on the outside, I believe if looked after they can last for over a decade.

Just checked a couple of mine, they are marked as bought new by me in 1994 and they appear as good as new. I mut admit the smaller aerosol type gas canisters used by cassette type mini cookers prolly only last a few years.
