Normalized 4140 alloy steel round bar is 4140 steel round bar after normalizing. After normalizing, 4140 steel bar can get better microstructure and hardness suitable for uses.
4140 steelis a Chromium-Molybdenum through-hardening steel of medium hardenability. It is a general purpose high-tensile steel with medium strength level and good impact properties. Similar to sae 1045 steel grade and sae 5140 steel grade, they are all medium carbon steel. But 4140 steel bar has better mechanical properties than 5140 and 1045 steel round bar.
4140 steel bar is one of the most popular used material to produce components, shafts, bolts such as high strength stud bolt, Threaded Rods, wind power bolt, pre-stressed anchor bolts, post stressed anchor bolt, Steel Tie Rod, tie bar, tension rod, Tension Bar etc. Shaft, axle shaft, crankshaft, shaft for sleeve, linear shaft, pump shaft, rotor shaft, sensor shaft, spline shaft, drive shaft, mandrel shaft, transmission shaft, screw rod etc. CNC machines, precision CNC machines etc. Ejector pins and Ejector rods.
We are a factory to process all kinds of steel bars on surface, size and microstructure. With complete production and processing facilities, we can supply all kind of pre heat treated 4140 steel bar and pre machining 4140 steel bar as following:
After the machining, 4140 steel can get precision size, various surface, better roughness, straightness etc. 4140 steel can be used for axe, pins, knives, gun barrels, gears, bolts, washers, hammer, sword etc.
As a Chinese steel bar professional manufacturer and supplier of more than twenty years, with complete produce and processing facilities, advanced testing equipments and big stock of steel bar, we can supply 4140 steel bar with good quality, competitive price, short delivery time and personalized customization.
