Product Description

 Product Description

Hot Rolled AISI 4140 Scm440 42CrMo4/1.7225 Alloy Steel Round Rod/Bar

1: AISI 4140 steel introduction
AISI 4140 is defined as a low alloy steel which has 1% Cr-Mo as strengthening alloy elements.Compared with AISI 4130, it has a higher carbon content with good balance of strength, toughness ,abrasion and impact resistance and heat treatment capabilities,but poor in weldability characteristics.AISI 4140 is generally supplied in quenched and tempered condition with hardness 28-32HRC

Product Parameters

Grade Application:

EN43B is used commonly for many general engineering applications. Typical applications include springs, shafts, bushes, crankshafts, screws, sickles, axes, knives, woodworking drills, and hammers.

Chemical composition:

The following table shows the chemical composition of EN43B steel:

Element	C	Si	Mn	S	P	Cr	Ni	Cu
Content (%)	0.45-0.50	0.07-0.35	0.7-1.00	≤0.05	≤0.05	-	-	-

Mechanical Properties:

Grade	Tensile Strength (Mpa)	Yield Strength (Mpa)	Elongation in 100-150 mm(%)	Reduction in Area	Hardness
En43B	≥380	≥210	≥25	≥50	≤111HB

Hardness:

Heat treatment:
Heat treatment temperatures, including the rate of heating, cooling, and soaking times, etc. will vary due to factors such as the shape and size of each steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium, and workpiece transfer facilities.

Hardening:
Temper the EN43B spring steel component immediately after quenching whilst tools still hand warm. Re-heat to the tempering temperature then soak for one hour per 25 millimeters of a total thickness (2 hours minimum) Cool the steel in the air. For most applications tempering will be between 550-660°C.
