Question

Identify the systematic B.I.S designations of three (3) of the following ferrous metals by stating the percentages of the constituent elements.

a) 45C8
b) Fe250
c) XT30Ni4Cr2V65
d) 37Mn2

Answer 1

The systematic B.I.S designations and percentages of three ferrous metals are provided.

Step-by-step explanation:

The systematic B.I.S designations provide information about the constituent elements of the ferrous metals. Here are the designations and percentages of three of the given metals:

a) 45C8 - This designation indicates that the metal contains approximately 45% carbon. The number following 'C' represents the carbon content in the metal.

b) Fe250 - This designation indicates that the metal is iron and contains approximately 250 parts per million (ppm) of impurities.

c) XT30Ni4Cr2V65 - This designation indicates that the metal is a complex alloy consisting of multiple elements. The percentages of the constituent elements are as follows: 30% of element X, 4% of nickel (Ni), 2% of chromium (Cr), and 65% of vanadium (V).
