Principal Design Features
300M is a low alloy, vacuum melted, steel of very high strength. Essentially it is a modified AISI 4340 steel with silicon, vanadium and slightly greater carbon and molybdenum content than 4340. 300M has a very good combination of strength (280 to 305 ksi), toughness, fatigue strength and good ductility. It is a through hardening alloy.
Applications
Applications for 300M steel are those that require strength in the 290 - 300 ksi range, such as aircraft landing gear, high strength bolts and airframe parts.
Machinability
Machining is best accomplished with the alloy in the normalized or normalized and tempered condition. Final machining to finish tolerances is done by grinding with care due the hardness of the heat treated alloy (Rockwell C 55). It is important to do a stress relief anneal at 550 F after finish grinding.
Forming
Formability by conventional methods is good in the annealed condition. The alloy behaves much like AISI 4340 steel.
Welding
300M can be welded by fusion methods or by flash resistance welding. Approved procedures must be used for fusion welding, including pre and post-heating practice, because the alloy will air harden due to heat input from welding. Following welding it is essential to re-normalize or re-normalize and temper prior to the final hardening heat treatment.
Heat Treatment
300M must be normalized at 1700 F before hardening. After the normalizing treatment the alloy is hardened by heating to 1600 F and oil quenching. Tempering is then done last.
Forging
No data. The alloy is forgeable - contact the supplier for details.
Hot Working
No data. Heat input can cause this alloy to air harden. Contact the alloy supplier for information as to the advisability of hot working.
Cold Working
In the annealed or normalized condition the alloy has good ductility and can be readily cold worked by conventional methods.
Annealing
Anneal at 1550 F and slow furnace cool at a rate of less than 50 F per hour down to 600 F. From there it may be air cooled.
Aging
Not applicable to this alloy.
Tempering
Temper at 600 F to give a nominal 300 ksi strength.
Hardening
300M hardens from cold working and by heat treatment. See "Heat Treatment" and "Tempering".

Principal Design Features
AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. The alloy can be hardened by heat treatment.
Applications
Typical applications for 4130 low alloy steel include. structural use such as aircraft engine mounts and welded tubing applications.
Machinability
This alloy is readily machined by conventional methods. Machinability is best with the alloy in the normalized and tempered condition. Although the alloy may be machined in the fully heat treated condition, machinability becomes more difficult with increasing strength (hardness) of the alloy.
Forming
Formability is best in the annealed condition for which the ductility is very good, Bend radii of 1t on annealed sheet material may be made.
Welding
4130 alloy is noted for its weldability by all of the commercial methods.
Heat Treatment
Heating at 1600 F followed by an oil quench will harden the 4130 alloy. For best results a normalizing pre-hardening heat treatment may be used at 1650 to 1700 F followed by the 1600 F soak and oil quench.
Forging
Forge at 2200 F maximum down to 1750 F.
Hot Working
4130 in the annealed condition has excellent ductility. Thus it is usually not necessary to do hot working to form parts. If hot working is needed it can be done in the range of 2000 F to 1500 F.
Cold Working
Cold working by conventional methods is readily accomplished on this alloy.
Annealing
4130 (and most of the other low alloy steels) may be annealed at 1550 F for a time long enough to allow thorough heating of the section size. It should then be cooled in the furnace at a rate of less than 50 F per hour down to 900 F, followed by air cooling from 900 F.
Aging
Not applicable to this alloy.
Tempering
Tempering is done to restore some of the ductility that may be lost after the hardening heat treatment and quench. Alloy 4130 is tempered at between 750 F and 1050 F, depending upon the strength level desired. The lower the tempering temperature the greater the strength.
Hardening
Hardening is accomplished by heat treatment or by cold working -- see "Heat Treatment".
Other Comments
The 4130 alloy is a through hardening alloy and should not be case hardened.

Nice deal Bruce. Not sure why you thought my thread was a **** Bruce thing, it was simply an option for people who didn't want to to wait til Christmas and get the 4340 shafts at a fair price and also to ALWAYS have them available. I kept my source for what I thought was a good reason, Mark Williams Enterprises does phenomenal work and they are serious in what they do and don't need a bunch of people beating down their door asking how much cheaper they could do it. They have better things to do. This was my vision of what would happen had I posted that info.
At any rate, I always respected you and your truck and what you've done with it, my interest in getting this job done was just that, NEVER meant any harm to you by it.
Hope these turn out good, I may be in for one if they do. Good luck!!
