Chemical Composition of Steel
Steel is the generic term of large family of iron. Some elements are intentionally added to iron for the purpose of attaining certain specific properties and characteristics. and Other elements are present incidentally and cannot be easily removed.
Many product specifications have mandatory requirements for reporting certain elements and these vary. Most mills routinely provide heat analysis which includes the elements below. Although it is possible to analyze for other elements this is most often not practical or necessary unless they are additions (e.g. Pb – Lead, Sb – Antimony or Co - Cobalt).
C – Carbon
Mn – Manganese
P – Phosphorous
S – Sulphur
Si – Silicon
Cu – Copper
Ni – Nickel
Cr – Chromium
Mo – Molybdenum
V – Vanadium
Cb (Nb) – Columbium (Niobium)
Ti – Titanium
Al – Aluminum
N – Nitrogen
B - Boron
Sn - Tin
Ca – Calcium
There are thousands of steel alloys and their categorization is complex and varies by governing body. Most, however, can be broadly grouped into Plain Carbon Steel, Ultra Low Carbon (ULC) Steel, High Strength Low Alloy (HSLA) Steel, Alloy Steel, High Alloy Steel (including Stainless Steel and Tool Steel) and Electrical Steel. Advanced High Strength Steel (AHSS) is the newest classification of steels.
Alloying elements often serve different purposes in different steels. For example, Manganese contributes to steel’s strength and hardness in the as rolled condition but another important characteristic is its ability to increase hardenability which is critical in heat treating.
