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 .

And cooling in in sand or dry lime is recommended etc. 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.
Following forging operation the work piece should be cooled as slowly as possible. You have the detailed data of steel below. Contact me and let me know your requests anytime.
The tempering temperature for depends upon the strength level desired.
AISI is also one kind of nickel chromium molybdenum steels. 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 Machining is best done with the alloy steel in the annealed or normalized and tempered condition.
It can be readily machined by all conventional methods such as sawing, turning, drilling etc. August 12th, 0 Comments.

Steel Grade required 36CrNiMo4 1. AISI steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections.
AISI steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Hardened and tempered alloy steel can also be nitrided, giving a surface hardness of up to Rc November 21st, 0 Comments.
Pre matrial and tempered steels can be further surface hardened by flame or induction hardening and by nitriding. Black, Rough Machined, Turned or as per given requirements.
December 10th, 0 Comments. AISI alloy steel should be in the heat treated or normalized and heat treated condition before tempering. For highly stressed parts it is excellent choice. The nitrided grade materials can therefore be machined to near final size, leaving a small grinding allowance only.
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. Nitriding should be followed by slow cooling no quench reducing the problem of distortion. And we supply steel, steels as well. January 3rd, 0 Comments.

ASTM material is often utilized where other alloy steels do not have the hardenability to give the strength required. Mechannical Properties Heat Treated Condition. May 24th, 0 Comments. Fusion and resistance welding is also possible with our alloy steel.
