ST37 Carbon steel round bar

ST37 is a German standard (now superseded by EN 10025-2 S235JR) for structural steel sections and plates. Round bars of equivalent material are typically supplied as S235JR under standards for steel bars, not under the "ST37" designation for plates/sections. The description about cold-rolled strip and high surface finish pertains to cold-rolled sheet/coil products, not to structural round bars.

Round steel belongs to carbon structural steel for construction and machinery, while square steel belongs to carbon structural
steel for machinery. Both of them are simple section steel, and their section shapes are respectively round and square. Low carbon is mainly used for
drawing wire, forging rivets, bolts, nuts and other metal products of raw materials. Medium carbon round steel and square steel
are generally used to make mechanical structural parts.
