Alloy 4340 plate is another general purpose grade of steel used for industrial and machining applications. The inclusion of Nickel in Alloy 4340 helps simplify heat treatment. In addition, the Nickel in Alloy 4340 increases hardenability of the steel. An additional grade of Alloy 4340 is Alloy E-4340. 4340 ALLOY In Stock Castle Metals SiteAlloy 4340 plate is another general purpose grade of steel used for industrial and machining applications. The inclusion of Nickel in Alloy 4340 helps simplify heat treatment. In addition, the Nickel in Alloy 4340 increases hardenability of the steel. An additional grade of Alloy 4340 is Alloy E-4340.
A low alloy steel containing chromium, nickel and molybdenum, AISI 4340 demonstrates extraordinary toughness and strength in the heat-treated condition. With high ductility, it can be bent or formed by pressing or spinning in the annealed state. AISI 4340 is often used in power transmission gears and shafts along with other structural parts. AISI 4340 1.6511 36CrNiMo4 SNCM439 - Waldun SteelFull annealing is recommended for AISI 4340 before machining, AISI 4340 should be carried our at a nominal temperature of 830-850,hold suitable time for the steel to be thoroughly heated, then furnace cooling to 610 at a rate of 11 per hour, finally air cooling. 9.Hardening AISI 4340 Round Bars Suppliers & Manufacturers in India.AISI 4340 steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections. AISI 4340 is also one kind of nickel chromium molybdenum steels. 4340 alloy steel is generally supplied hardened and tempered in the tensile range of 930 1080 Mpa.
