1.1191 — alloy Steel: Composition, Properties & Applications
Also known as: 1.1191
1.1191 supplied by Shanxi Youte Steel (jlhsteel.net).
CHEMICAL COMPOSITION
C:0.42-0.50;Mn:0.50-0.80;Si:0.15-0.40
TYPICAL APPLICATIONS
Medium-carbon grade for machine parts such as gears, crankshafts, axles, connecting rods, spindles and forgings that need a balance of strength, toughness and machinability. Commonly supplied as bar, plate, sheet, tube and forging.
AVAILABLE FORMS
Bar, Plate, Tube, Forging, Wire
STANDARDS & EQUIVALENT GRADES
DIN EN 10083; C45 / AISI 1045
HEAT TREATMENT
Austenitize at 820–870 °C (oil or water quench depending on section) and temper at 400–650 °C to the required strength/toughness balance.
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).
SOURCE & SUPPLY
Shanxi Youte Steel stocks 1.1191 in bars, plates, pipes and forgings with mill test certificates, cut-to-length service and export packaging. Contact our team for quotations and technical data sheets.
