S235JR is common steel grade in European steel standard specification EN 10025-2 which are mainly used to produce structural parts of the bolted and welded steel in dustrial area.

 

SS400 in Japan steel specification JIS G3101 is also one mild steel grade.Grade S235JR and SS400 are both common carbon structural steels.Type steel plates are making steel tanks in Oil and gas industry.
