EN24 a popular grade of through-hardening alloy steel, readily machinable in the T condition. EN24T properties make it suitable for the manufacture of parts. EM24 steel (a.k.a. AISI ) has the following chemical composition (in wt% of alloying element): Nickel, Ni – Chromium, Cr – Manganese . EN24 Steel Properties. EN24 / m EN24 is usually supplied in the T condition with a tensile strength of / N/mm2. EN24 is a popular grade of .

January 3rd, 0 Comments. Machining is best done with the alloy steel in the annealed or normalized and tempered condition.

As mentioned above, pre-hardened and tempered steel bars or plates can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc Contact me and let me know your requests anytime. AISI steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. AISI alloy steel should be in propertifs heat treated or normalized and heat treated condition before tempering.


The nitrided grade materials can therefore be machined to near final size, leaving a small grinding allowance only.

For highly stressed parts it is excellent choice. August 12th, 0 Comments. Pre hardened and tempered steels can be further surface hardened by flame or induction hardening and by nitriding. Steel Grade required 36CrNiMo4 1.

Welding of steel in the hardened and tempered condition as normally suppliedis not recommended and should be avoided if at all possible, because of the danger of quench cracking, as the mechanical properties will be altered within the weld heat affected zone. The tensile strength of the steel material core is usually not affected since the nitriding temperature range is generally below the original tempering temperature employed.

Hardened and tempered alloy steel can also be nitrided, giving a surface hardness of up to Rc December 10th, 0 Comments. Black, Rough Machined, Turned or as per given requirements.

It can be readily machined by all conventional methods such as sawing, turning, drilling etc. May 24th, 0 Comments. Fusion and resistance welding is also possible with our alloy steel. Mechannical Properties Heat Treated Condition.

mzterial And we mmaterial steel, steels as well. And cooling in in sand or dry lime is recommended etc. Nitriding should be followed by slow cooling no quench reducing the problem of distortion. AISI is also one kind of nickel chromium molybdenum steels.

You have the detailed data of steel below. Following forging operation the work piece should be cooled as slowly as possible. The tempering temperature for depends upon the strength level desired.

AISI steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections. ASTM material is often utilized where other alloy steels do not have the hardenability to give the strength required.
