08Х — alloy Steel: Composition, Properties & Applications
Also known as: 08Х
Russian GOST chromium steel 08Х.
CHEMICAL COMPOSITION
C:0.05-1.05;Si:0.10-0.50;Mn:0.30-1.00;Cr:0.40-1.60;P:≤0.030;S:≤0.030
TYPICAL APPLICATIONS
International high-end steel for aerospace, oil & gas, defense or engineering.
AVAILABLE FORMS
Bar, plate, sheet, tube, forgings, strip, wire, powder
HEAT TREATMENT
Austenitize 830–880 °C (oil quench) and temper at 400–520 °C; stress-relieve formed springs at 230–320 °C after coiling.
PROCESSING PRECAUTIONS
Preheat and control interpass temperature when welding; post-weld heat treatment or stress relief is recommended to avoid hard-zone cracking. Use low-hydrogen electrodes. Protect from decarburization during heating (controlled atmosphere or protective coating). Shot-peen after coiling to improve fatigue life; avoid sharp bends and surface defects.
SOURCE & SUPPLY
