What is ASTM A285 steel steel plate

ASTM A285 steel is a kind of common carbon steel, whose tensile strength is low or mid-low. For ASTM A285 steel specification, there are three grades or levels: A285 Grade A, A285 Grade B, A285 Grade C.

ASTM A285 steel covers plate tensile strength range from 310-515Mpa. ASTM A285 steel plate is usually delivered as-rolled condition. ASTM A285 steel plate is made by killed, semi-killed, capped or rimmed steel practices according to the end users’ requirement.

ASTM A285 steel chemical composition:

Element Composition % Composition % Composition %
Grade A Grade B Grade C
Carbon, max (a) 0.17 0.22 0.28
Manganese, max      
Heat analysis 0.9 0.9 0.9
Product analysis 0.98 0.98 0.98
Phosphorus, max (a) 0.035 0.035 0.035
Sulfur, max (a) 0.04 0.04 0.04

(a)Applies to both heat and product analysis
