07Cr2MoW2VNbB — alloy Steel: Composition, Properties & Applications
Also known as: 07Cr2MoW2VNbB
Chinese GB creep-resistant steel for power plant.
CHEMICAL COMPOSITION
C:0.04-0.10;Si:≤0.50;Mn:0.30-0.60;Cr:1.90-2.60;Mo:0.90-1.30;W:1.50-2.00;V:0.20-0.30;Nb:0.02-0.08;B:0.0005-0.006;P:≤0.020;S:≤0.010
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
Powder/HSS: preheat 800–850 °C, austenitize 1180–1230 °C (salt or vacuum), quench, triple temper 540–570 °C to ≈64–66 HRC.
PROCESSING PRECAUTIONS
Risk of quench cracking and distortion — use graded preheating, controlled cooling and multiple tempers. Avoid overheating the austenitizing temperature. Machine in the soft annealed condition; allow for dimensional change after heat treatment. Grind with coolant to prevent rehardening cracks.
