07MnCrMoVE — alloy Steel: Composition, Properties & Applications
Also known as: 07MnCrMoVE
Chinese GB high-strength QT steel plate for LNG/storage.
CHEMICAL COMPOSITION
C:≤0.09;Si:0.15-0.40;Mn:1.10-1.60;Cr:0.10-0.40;Mo:0.10-0.35;V:0.02-0.08;P:≤0.020;S:≤0.008
TYPICAL APPLICATIONS
High-end / niche grade used in aerospace, defense, tooling, bearing, gear or heavy shaft applications.
AVAILABLE FORMS
Bar, plate, sheet, tube, forgings, strip, wire, powder
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.
