Product Description

scm440 alloy steel grade bar


    Our company is a manufacturer of  SCM440 alloy steel bar including SCM440 Alloy Steel Round Bar, SCM440 Alloy Steel Square Bar, SCM440 alloy steel flat bar, SCM440 alloy Square Steel Bar and SCM440 alloy Hexagonal Steel Bar.

    SCM440 steel is 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 S45C steel grade and SCR440 steel grade, they are all medium carbon steel.

    The difference between S45C steel material and SCM440 steel material: SCM440 steel has alloy element, it is kind of alloy steel bar. After heat treatment, SCM440 steel material can get between mechanical properties.

    SCR440 vs SCM440:  SCM440 steel grade has better hardenability than SCM440 steel material. After quenching and tempering, SCM440 can be whole pre hardened from core to side.

    What is SCM440 steel used for? SCM440 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.

6.      Processing of SCM440 steel:

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 SCM440 steel bar and pre machining SCM440 steel bar as following:

1)      Heat treatment of SCM440 steel

Oil quenching SCM440 steel / SCM440 normalizing steel / pre hardened SCM440 steel / annealing SCM440 steel / stress relieving SCM440 steel / SCM440 qt steel / flame hardening SCM440 steel / SCM440 steel induction hardening / case hardening SCM440 steel / SCM440 oil quenched / austempering SCM440 steel / SCM440 steel water quenched / nitriding SCM440 steel /  milling SCM440 steel

After heat treatment, SCM440 steel bar can get better heat treated SCM440 steel properties, for example:

    SCM440 steel quenched and tempered properties:

Yield strength of SCM440 steel: 930MPa min

Tensile strength of SCM440 steel: 1080MPa min

Elongation of SCM440 steel: 12% min

Reduction area of SCM440 steel: 50% min

Rockwell hardness of SCM440 steel: 32HRC min

Brinell hardness of annealed SCM440 steel: 217HB max

Vickers hardness of SCM440 steel: We can also guarantee the Vickers hardness based on your special requirements.

2)      Machining SCM440 steel:

knurling SCM440 steel / tapping SCM440 steel / grinding SCM440 steel / turning SCM440 steel / threading SCM440 steel / cutting SCM440 steel / drilling SCM440 steel / forging SCM440 steel / laser cutting SCM440 steel / reaming SCM440 steel / stick welding rod for SCM440 steel /  bending SCM440 steel / brazing SCM440 steel / straightening SCM440 steel / tg&p SCM440 steel / polishing SCM440 steel / cold drawing SCM440 steel

     After the machining, SCM440 steel can get precision size, various surface, better roughness, straightness etc. SCM440 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 SCM440 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.
