Product Description
sae 4140 alloy steel bar equivalent spec
Our company is a manufacturer of sae 4140 alloy steel bar including sae 4140 Alloy Steel Round Bar, sae 4140 Alloy Steel Square Bar, sae 4140 alloy steel flat bar, sae 4140 square alloy steel bar and sae 4140 hexagonal alloy steel bar.
What is 4140 steel? 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, the y are all medium carbon steel.
The difference between sae 1045 steel material and sae 4140 steel material: sae 4140 steel has alloy element, it is kind of alloy steel bar. After heat treatment, sae 4140 steel material can get between mechanical properties.
Sae 5140 vs sae 4140: sae 4140 steel grade has better hardenability than sae 5140 steel material. After quenching and tempering, sae 4140 can be whole pre hardened from core to side.
What is 4140 steel used for? 4140 steel bar is mainly used to produce 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. We welcome old and new customers to inquire to us for technical questions and demands.
