AISI steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections.

AISI is also one kind of nickel chromium molybdenum steels. Pre hardened and tempered steels can be further surface hardened by flame or induction hardening and by nitriding.

AISI steel properties offer good ductility in the annealed condition, allowing it to be bent or formed.

Fusion and resistance welding is also possible with our alloy steel. ASTM material is often utilized where other alloy steels do not have the hardenability to give the strength required.


For highly stressed parts it is excellent choice. You msterial the detailed data of steel below. Following forging operation the work piece should be cooled as slowly as possible. And cooling in in sand or dry lime is recommended etc. 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. 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 Hardened and tempered alloy steel can also be nitrided, giving a surface hardness mategial up to Rc Nitriding should be followed by slow cooling no quench reducing the materail of distortion.

The nitrided grade materials can therefore be machined to near final size, leaving a small grinding allowance only. 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. Machining is best done with the alloy msterial in the annealed or normalized and tempered condition. It can be readily machined by all conventional methods such as sawing, turning, drilling etc.


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 we supply steel, steels as well. Contact me and let me know your requests anytime.
