AISI 4340 steel or Chromoly Steel - materialwelding.com
WebStraightening: Best done warm 400-800F (205-425C). Hardening: (Atmosphere or Vacuum Furnace). Preheat: 1200-1250 (650-675C), equalize. High Heat: 1475-1500F (800-815C), soak 10 to 30 minutes. For vacuum hardening, use the high side of the high heat range and soak times. Quench: Oil quench to hand warm, 150F (65C). 4340 steel is an ultra-high strength steel classified a medium-carbon, low-alloy steel. 4340 steel has high strength, ductility, toughness, creep resistance, and fatigue resistance relative to most other steels. Hardness ranging from 24 to 53 HRC can be achieved, depending on the heat treatment. WebThis alloy steel is tempered at 454 to 635°C (850 to 1175°F) for the lower strength 125 to 200 ksi level. AISI 4330 alloy steel is tempered at 218 to 260°C (425 to 500°F) for the 260 to 280 ksi level. Tempering is not recommended for strength levels in the 220 to 260 ksi range as this will lead to degradation of impact strength. shriver management group
