• Silicon 0.35 max
• Nickel 1.0-2.0
• Chromium 11.0-13.0
• Molybdenum 0.5-0.7
• Vanadium 0.20-0.45
• Iron remainder

Heat Treatment of Jethete M151™

• Anneal by heating to 1292°F (700°C), then air cooling
• Harden
  • Heat to 1922°F (1050°C)
  • Air quench
  • Temper at 932° to 1292°F (500° to 700°C)

Applications of Jethete M151™

• Structural parts for gas turbines

Weldabilty of Jethete M151™

• Argon arc methods provide acceptable mechanical properties and consistent structure
• Heat treatment pre- and post-welding assures high tensile strength

Workability of Jethete M151™

• Once annealed, can be bent, drawn or spun
• Easily forged – preheat to 1400° to 1450°F (760° to 788°C); quickly heat to 2050° to 2102°F (1121° to 1150°C). Forge above 1450°F (788°C) only
• Cool to 212°F (100°C); quickly anneal at 1256° to 1292°F (680° to 700°C), then  air cool
