Problems in argon arc welding of 304 × 0.8 thick stainless steel plate and 201 × 0.8 thick stainless steel plate Description: 304 × 0.8 thick stainless steel plate and 201 × 0.8 thick stainless steel plate are welded by argon arc welding. Will the weld crack? What's more, will 201 board rust under 150 ℃ high temperature and 95% high humidity?
Answer: in principle, it should not crack and rust. 201 is easy to rust
Question: is the welding seam rusty or the whole piece rusty in this high temperature and high humidity environment?
Answer: the 201 × plate is easy to rust in the weld and the scratched part!! 201 × the material itself is not as good as 304 in terms of oxidation resistance and corrosiveness!!! The service life itself is short, but there will be no problem in a short period of time. There should be no problem in two or three years.
