REG Metals supplies 4340 Steel Sheet (AISI 4340 Alloy Steel Sheet) for aerospace, defense, automotive, tooling, heavy equipment, power generation, and high-performance engineering applications. AISI 4340 is a nickel-chromium-molybdenum alloy steel known for its exceptional high strength, toughness, fatigue resistance, hardenability, and wear resistance.
4340 Steel Sheet is commonly used in applications requiring superior mechanical performance under high stress, impact loading, and cyclic fatigue conditions. It can be heat treated to achieve very high tensile strengths while maintaining excellent toughness, making it a preferred material for aircraft components, gears, shafts, structural parts, landing gear components, and heavy-duty machinery.
REG Metals supplies 4340 Steel Sheets in various thicknesses, widths, lengths, heat treatment conditions, and surface finishes. Material can be supplied with full certification, including Mill Test Reports (MTR), Certificate of Analysis (COA), and material traceability.
