1.1321 — alloy Steel: Composition, Properties & Applications

Also known as: 1.1321
EN/DIN steel grade 1.1321

CHEMICAL COMPOSITION
C:0.10-0.25;Si:0.10-0.40;Mn:0.30-1.50;Cr:0.30-1.20;P:≤0.035;S:≤0.035

TYPICAL APPLICATIONS
General engineering and manufacturing use per EN/DIN specification.

AVAILABLE FORMS
Bar, plate, sheet, tube, forgings, strip, wire

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. Carburize 900–930 °C, direct/intake quench, temper 150–200 °C; useful case depth 0.5–1.5 mm.

PROCESSING 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). Machine the core stock before surface hardening; leave grinding allowance for the hardened case.
