2815

AISI/SAE 2815 carbon / alloy steel.

Chemical Composition (%)

C0.15
MN0.3
P0.03
S0.03

Applications

International high-end steel grade for aerospace, oil & gas, defense or engineering machinery.

Available Forms

Bar, plate, sheet, tube, forgings, strip, wire, powder

Uses

Low-carbon grade used for welded structures, shafts, pins, bolts, nuts, seamless tubes and general engineering components where moderate strength and good weldability are required. Commonly supplied as bar, plate, sheet, tube and forging.

Heat Treatment

Typically normalized (880–920 °C, air cool) or carburized (900–930 °C) for case-hardening grades, then quenched and tempered at 150–200 °C.

Precautions

Weldable with standard procedures; preheat may be needed for thick sections or higher-carbon/ alloy grades. Protect from decarburization during heating (controlled atmosphere or protective coating).
