Heat Treatment of SAE/AISI 4340 Alloy Steel 4340 Steel Annealing Slowly heat to 8008500 ºC, keep enough time, ensure heat thoroughly. then cooling in furnace to 480 ºC, then cool in air. After annealing, the hardness 92 HBS Max. AISI 4340 Steel Hardening & Quenching
Alloy 4340 can be hardened by a heat treatment followed by an oil quench, or simply by working it while cold. 4340 has average density for a steel alloy, melts at a relatively high temperature (2,600 degrees Fahrenheit) and is malleable enough to be cold worked, or worked in a non-heated state. AISI 4140 Alloy Steel (UNS G41400)Sep 07, 2012 · Alloy steels are designated by AISI four-digit numbers and comprise different kinds of steels, each with a composition which exceeds the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va set for carbon steels. AISI 4140 alloy steel is a chromium-, molybdenum-, and manganese-containing low alloy steel. It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. The following datasheet gives an overview of AISI 4140 alloy steel AISI 4340 Alloy Steel Tool Steel AISI 4340 Steel Grade Virat Special Steels is the largest Supplier & Stockiest of AISI 4340. 40NiCrMo84 is high tensile alloy steel famed for its wear resistance properties and in addition where high strength properties are required. This Grade is used in components akin to gears, shafts,
Boltport Fasteners is a manufacturer and supplier of AISI 4340 Fasteners such as bolts, screws, stud bolts, threaded rods, nuts, washers and other bolting components. AISI 4340 is a chromium-molybdenum alloy steel with high strength properties, used for manufacturing wide range of fasteners across ASTM and ISO bolting standards. Mechanical properties and microstructural features of AISI 4340 high-strength alloy steel, supplied in the form of an extruded bar of 25.4 mm diameter, is used in this study, its chemical composition being given in Table 1. AISI 4340 steel is a low-alloy martensitic steel that can be heat treated to provide a wide range of SAE-AISI 4340 (SNCM439, G43400) Ni-Cr-Mo Steel May 30, 2020 · SAE-AISI 4340 steel is an alloy steel formulated for primary forming into wrought products. 4340 is the designation in both the SAE and AISI systems for this material. G43400 is the UNS number. It can have a moderately high tensile strength among SAE-AISI wrought steels.
