What is Steel? Part 2: Medium-Strength and Conventional High-Strength Steels
A good rule of thumb: The transition from mild steel to high-strength steel occurs at a yield strength of about 30 KSI (210 MPa). For yield strengths between 30 and 50 KSI, metalformers typically provide a simple carbon-manganese (C-Mn) steel, unless other restrictions are placed on the order. The composition of these steels approaches that of low-carbon mild steels, except that C-Mn steels contain more carbon and manganese to increase strength to the desired level. No special alloying or thermal treatments are needed at the mill, making these alloys relatively inexpensive. Unfortunately, this approach usually is not practical for yield strengths greater than 50 KSI, due to a drop-off in elongation and weldability. This limits the use of C-Mn steels to those parts without complex requirements for shape, strength or weldability. ...
