High Strength Steel Sheet Uniform Designator System

1.	Sheet Product Prefix
	HR = Hot Rolled
2.	Yield Strength
	Numerical description of minimum yield strength in ksi
3.	Chemical Composition
	Each steel is designated by a letter classification
		S = Structural Steel
		X = Low Alloy
		W = Weathering
4.	Inclusion Shape Control
	F = Killed Plus Inclusion Shape Control X = Killed without Inclusion Shape Control
5.	Tensile Strength
	Numerical description of the minimum tensile strength in ksi
