Medium Carbon Alloy Structure 4130 Steel Material - China

AISI 4130 Steel Round Bar Sheet Plate, 25CrMo4, JIS SCM430

AISI 4130 steel also can be called JIS SCM430 steel, 25CrMo4(1.7218) steel.

4130 alloy steel round bar has high strength and toughness and the hardenability is high.

And the hot strength of AISI 4130 is good by hardening in the oil.

At the temperature of lower than 500℃, it will get enough strength.

But if the temperature is 550℃, that will get decrease markedly.

If you feel interested in it, you can check 4130 steel heat treatment, properties and chemical composition as below.

By the way, at the level of Alloy structure steel, they have good hardenability.

After the good heat treatment, the sorbite and bainite of microstructure will be uniform.

So they will get higher tensile strength, yield ratio, toughness and fatigue strength.

So they are good material for machine fittings with a big size of cross-section.

AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard.

ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel, containing nominally 0.28-0.33% Carbon, 0.8-1.1% Chromium and 0.15-0.25% Molybdenum.

It is similar to 4140 steel which has a higher carbon level (0.28-0.33%), giving 4130 material improved weldability, at the expense of through thickness strength.

With the proper heat treatment it is also readily machined.

Annealing ASTM 4130 alloy steel offers excellent ductility.

AISI 4130 steel is usually supplied as round bar commonly in the hardened and tempered condition.

AISI/SAE 4130 steel grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength up to around 315º C (600º F).

It shows good overall combinations of strength, toughness and fatigue strength.

4130 Alloy Steel Application

This type of steel usually is used after the quenching and tempering.

Because after that, it can get high properties to satisfy the needs of the industry.

It is a good choice for the fittings which has a big size of cross-section and works on the high-stress condition of the machine-building industry.

Such as the shaft, steering wheel which sustain high load capacity, screw bolt, gear wheel and etc.

And it is used to make fastening pieces, flange and blind flange of the production of boilers.
