16 MnCr5 steel round steel imported from German, equivalent to China's 16 CRMNH steel (GB/T 5216-2004), has good hardenability and cutting parts with large cross section, after heat treatment can obtain higher surface hardness and wear resistance, low temperature impact toughness is higher also.

Rebar marking in the graphical method of reinforced concrete components:

Generally, the method of using outgoing lines is used, and there are two specific annotation methods:

1。 Number, diameter, and grade of labeled steel bars: 3 Ф 203: represents the number of steel bars

Ф： Denotes the diameter symbol of the steel bar grade

20: Denotes the diameter of the steel bar

2。 Label the grade, diameter, and center distance of adjacent steel bars

Ф 8 @ 200：

Ф： Denotes the diameter symbol of the steel bar grade

8: Denotes the diameter of the steel bar

@: Equal center distance symbol 200: Center distance between adjacent steel bars (≤ 2
