4140 alloy steel round bar is an cold drawn annealed steel. It offers god weldability without compromising steel abrasion and impact resistance. 4140 alloy steel bar is commonly used in structural applications including gears, fasteners and some aircraft exterior.
The 4140 alloy steel round bar has an unpolished (mill) surface and has a standard tolerance. 4140 alloy steel grade contains chromium and molybdenum for high strength and has good machinability. 4140 alloy responds well to heat-treatment and is relatively easy to machine in the annealed condition. 4140 alloy steel round bar has good strength and wear resistance, excellent toughness, coupled with good ductility, and the ability to resist stress at elevated temperatures.
Specifications: ASTM A331, AISI 4140
AKA: CDA Alloy Flat, 4140 Rectangle Bar
Applications: brake dies, fixtures, jigs, blades, tool holders, etc.
Workability: Moderate to Weld, Cut and Machine.
Mechanical Properties: Brinell = 223, Tensile = 102,000 +/-, Yield = 90,000 +/-
4140 cold rolled alloy steel can be used for as wide variety of applications where greater toughness and wear resistance is needed over lower carbon grades. Typical applications include strippers, holder blocks, mold bases, ejectors, back up and support tooling, fixtures, jigs, molds, cams, drill collars, bolts, stubs, couplings, reamer bodies, axles, shafting, piston rods, rams, hydraulic machinery shafts, gears, sprockets, gear racks, valves, chain links, spindles, tool bodies, tool holders, tie rods, boring bars, guides, tracks, ways, slides, wear strips or parts, forming dies, brake dies, trim dies, bolsters, machinery parts and components, etc.

GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
