Hello,

A google search provided the following info. EN Steel. Hope this gets you started.

Please do not confuse these EN with the current EN. EN 8 is just plain AISI 1040, EN 24 is a gear material, give me some time to dig it out or may be any local steel merchant should help....

These EN specs (not current European EN steel) are prevalent in Indian steel markets since last 60 years.

This is further to the details already given for EN8 and EN24 Steels earlier.

It is from BS 971 standard steels, now have changed in numbers, which I do not have at present.

EN24 is a (1.5% Ni,Cr,Mo) steel in US equivalent to SAE 4340,

Chemical Composition % - Carbon 0.35-0.45/ Silicon 0.10-0.35/ Manganese 0.45-0.70/ Nickel 1.30-1.80 / Chromium 0.90-1.40/ Moly 0.20-0.35/ Sulphur 0.050 (max)/ Phosphorous 0.050(max).

Mechanical Properties -

Limiting Ruling Section (in) - 6

Tensile Strength (tons/sq.in.) - 55 (min)

Proof Stress (tons/sq.in.) - 41 (min)

Elongation % - 18 (min)

Izod Impact Value (Ft.Lb.) 40(min)

Weldability - POOR

Application - High tensile steel suitable for pump shafts and turbine rotors in general and for similar uses. Non-preferred but sometime used in place of EN 27 steel when the later not available.

EN8 in US equivalent is to AISI - C 1038/ C1041,

Chemical composition % - Carbon 0.35-0.46/ Silicon 0.05-0.35/ Manganese 0.60-1.0/ Sulphur 0.06(max)/ Phosphorus 0.06(max).

Mechanical properties - normalised /hardened and tempered

Limiting Ruling Section (in) - 6 /2 1/2

Tensile Strength (tons/sq.in) - 35 (min) /40 (min)

Yield Strengh (tons/sq.in.) - 18 (min) /28 (min)

Elongation % - 20 /22

Izod Impact Value (Ft.Lb) - 25 (min)

Weldability POOR

Application - Medium strength material used for nuts, for high tensile studs and for rotor forgings. Obtainable in various grades A,B,C,D, and E according to properties required.

HI guest,

Bright bars, as the name suggests, are machined to required perfection and may have different chem comp, mech properties, and therefore, different applications; however, most of the time they are made up of plain mild steel (AISI 1030).

Best regards,

Nachi

En8 is low carbon stell, having superior properties than mild stell, and can be heat treated to increse the hardness slightly. easily machinable

En24 is alloy steel, having high superior mechanical properties, hard, tough, can be for high strength applicaion heat treated to increse considerable hardness .

Put this in commercial space. In fact you may search the globalspec for probable suppliers (even search the yellow pages of local subdirectory)

Posting here and that too off topic, may not attract any eyes.

And after contact us you have not put where to contact?

Do not put e-mail addresses. Better to get registered, then automatically prospective suppliers can contact you through the confidential e-mail address.

BTW: just to clarify, no, we do not supply, but there are a lot of registered members willing to.
