4140 heat treated alloy is a chromium-molybdenum, medium carbon alloy steel, and is used in a wide variety of applications requiring high strength and toughness. The chromium imparts good hardness penetration while molybdenum provides hardness uniformity and strength.
4140 Sheet Metal - HENAN STEEL GUANG INTERNATIONAL Alloy constructional steel / Alloy steel - 4140 sheet metal has suitable hardenability, after suitable metal heat treatment, its microstructure is homogeneous sorbite, bainite or very fine pearlite. Therefore, it has quite high tensile strength and flexion ratio (generally at about 0.85), high toughness and fatigue strength, and low toughness
AISI 4140 alloy steel can be cold worked using conventional methods in the annealed condition. Annealing. AISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace. Tempering. AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level.
