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 .

AISI steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Nitriding should be followed by slow cooling no quench reducing the problem of distortion. 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.

And cooling in in sand or dry lime is recommended etc. Machining is best done with the alloy steel in the annealed or ne24 and tempered condition. Following forging operation the work piece should be cooled as slowly as possible. January 3rd, 0 Comments.

AISI alloy steel should be in the heat treated or normalized and heat treated condition before tempering. The tempering temperature for depends upon the strength level desired.

And we supply steel, steels as well. December 10th, 0 Comments.

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 Black, Rough Machined, Turned or as per given requirements. You have the detailed data of steel below.

ASTM material is often utilized where other alloy steels do not have the hardenability to give the strength required. Contact me and let me know your requests anytime.

Steel Grade required 36CrNiMo4 1. 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. Fusion and resistance welding is also possible with our alloy steel. Mateial nitrided grade materials can therefore be machined to near final size, leaving a small grinding allowance only.


May 24th, 0 Comments. November 21st, 0 Comments. AISI is also one kind of nickel chromium molybdenum steels. Hardened and tempered alloy steel can also be nitrided, giving a surface hardness of up to Rc AISI steel is a medium carbon, low alloy steel known for its toughness and strength materila relatively large sections.

Mechannical Properties Heat Treated Condition.

It can be readily machined by all conventional methods such as sawing, turning, drilling etc. Pre hardened and tempered steels can be further surface hardened by flame or induction hardening and by nitriding.
