In reply to John Kelly:
This is interesting, however as an ill informed non-chemist may I get enlightened by crowd knowledge?
- 304 denotes the stainless steel quality, and if so, aren't we looking mainly at 316L currently?
- if sulfur is the main agent, processes are different in limestone? Just to know if this has relevance for my own bolt use.
Sorry for my lack of school chemistry, and thanks for more information.
