is a medium alloyed high speed steel which has good machinability. The
H-SS M2 chemical composition gives a good combination of well-balanced
toughness, wear resistance and red hardness properties. Widely used for
cutting tools such as twist drills, taps, milling cutters, saws, knives
etc. Also commonly used in cold work punches and dies and cutting
applications involving high speed and light cuts.
Grade M2 High Speed Steel is by far the most popular high speed steel replacing high speed steel gradein most applications because of its superior properties and relative economy.

4. Forging of AISI M2 High Speed Steel
heat M2 HSS steel slowly and uniformly to 850-900°C. The heat should
then be increased more quickly to the forging temperature of
1050-1150°C. If during the forging
the temperature of the M2 high speed tool steel material drops below
880-900°C, re-heating will be necessary. Cool the M2 steel component
very slowly after forging.
5. Heat Treatment of M2 Steel HSS
to 1600° F, soak thoroughly at heat. Furnace cool 25° F per hour to
900° F, air cool to room temperature. Approximate annealed hardness 241
Stress Relief of Unhardened Material: Heat slowly
to 1200 to 1250° F. Soak for two hours per inch of thickness at heat.
Slow cool (furnace cool if possible) to room temperature.
Preheat: Heat slowly to 1550° F, soak thoroughly, heat to 1850° F, soak thoroughly.
time in the furnace varies from a few minutes to a 15 minutes,
depending tool size, heat capacity of the furnace, and the size of the
charge. – Heat to 2150 to 2200° F for max. toughness and minimum
distortion. – Heat to 2250 to 2275° F for max. hardness and abrasion
hardness, oil quench to 150-200° F. Air quench to 150° F. When quenching
in hot salt maintain the quench just above the Ms temperature. After
equalizing withdraw parts from the hot salt and air cooled to 150° F.
temper is mandatory, three tempers are sometimes preferred. Soak for 2
hours per inch of thickness. Air cool to room temperature between
tempers. The best tempering range for hardness, strength and toughness
is 1000 to 1050° F.

6. Machinability of AISI M2 Tool Steel H-SS
of HSS M2 tool steels can be carried out using grinding methods.
However, they have poor grinding capability and hence they are regarded
as “medium” machinability tool steel under annealed conditions. The
machinability of these tool steels M2 is only 50% of that of the easily
machinable W group or water hardening tool steels.
7. M2 Tool Steel Applications
The main use of high-speed steels continues to be in the manufacture of various cutting tools.
applications for M2 high speed steel are twist drills, reamers,
broaching tools, taps, milling tools, metal saws. M2 is suitable for
cold forming tools such as extrusion rams and dies, also widely used in
all kinds of cutting tools, knife and punches and die applications,
plastic moulds with elevated wear resistance and screws.

Sorry in advance to the poor video, the video was not planned but i decide to share it anyways.
Anyone could build this type of American muscle if you set your mind to it.
For those of you that would like to pick apart my work Here is a brief Biography on me: I’m married ( Married 14 yrs sept 2016 w/ 3 children), and own two homes. I would like you to know that I built this without ever using a credit card. (that has always been my number one rule: If I can’t use a debit card then I probably can’t afford it.) I started building my first supercharged 1967 Camaro within a year after buying my first house at age 20 which I completed by age 24. Then started building my 72 Camaro which I completed by age 26. Each time I build a car it becomes better then the previous car so there is a very large learning curve. To own a car this bad ass without being a penny in debt for it is a huge accomplishment. Obviously everything is not perfect but I have plenty of time to work at it. Plus if everything was perfect I wouldn’t have anything to tinker with and that would be no fun.
I’ll try and list as many details about the car as I can. Let’s start with the motor: It’s a balanced & blueprinted .030 over 454 that was just built at the end of this summer. The block was o-ringed and uses .062″ copper head gaskets. It has a fresh forged steel crank, new bearings, resized Eagle I-beam rods, Ross 8.8:1 blower pistons, (Compression Ratio is about 8.5:1 with the .062″ head gaskets) it has new Total Seal rings, a new Howards solid roller cam (.702 Lift, 308/314 Duration) new Howards solid roller lifters, and new Howards double valve springs. It has the large GM oval port heads (3964290) that were just ported & polished. The exhaust ports were also D-shaped for maximum flow. It has Manley stainless steel valves, bronze valve guides and new valve seals. It has Crane Gold 1.7 aluminum roller rockers and Manley guide plates. It has a new Cloyes double roller timing chain, a new 7qt oil pan, a new windage tray and crank scraper, new high volume oil pump & pickup. It has a custom “one-off” oval port intake manifold that was also ported to match the heads. It has a Weiand 8-71 Polished Blower, and two fresh rebuilt Holley 750 double pumpers. It has an MSD Pro-billet distributor, MSD 7-AL box with a Stage-2 module (Rev-limiter). It has a Moroso high volume water pump, an Afco Racing aluminum radiator w/dual 12″ electric fans, 1-7/8″ Dynomax headers leading to 3″ exhaust with 40 series Flowmasters.
It has a built 2sp Powerglide with a shift kit and a 3000 stall converter w/anti-balooning plates. (It also has a Biondo line lock) The rearend is a narrowed Ford 9″ with a back brace, 35 spline Strange axles, and 4.88 gears inside a locker center section. It has Art Morrison ladder bars with a diagonal link, Afco Racing adjustable coilover shocks, and it also has (Wilwood) 4 wheel disc brakes with an adjustable porportioning valve that you can adjust from the dash. It has 15×15 & 15×3.5 Weld Draglite wheels. The rear tires are 32×17.5″ Mickey Thompson ET Streets, and the fronts are 165/R15 radials. It has Competition Engineering subframe connectors, wheel tubs and wheelie bars out back. The interior has a 12pt roll that also extends through the firewall and ties in with the front clip. It has a custom made aluminum dash covered in black vinyl, and has all Autometer Ultra-Lite silver gauges, including a 5″ tach w/shift light. (Gauges include: Water Temp, Trans Temp, Oil Pressure, Fuel Pressure, Fuel Level, Boost, & Volts) It has a Hurst quarter stick shifter with a pistol grip handle. It has black carpeting throughout the inside of the car. The custom seat covers match the door panels. It also has a Harwood 3.5″ fiberglass cowl induction hood. It has a new 20 gallon RCI aluminum fuel cell w/sending unit in the trunk. The battery is also relocated to the trunk as well as a Holly Blue electric fuel pump. It has a Barry Grant fuel pressure regulator and an inline fuel filter. It has all A.R.P. bolts in the motor, and all the fuel & vacuum lines are braided steel. It also has dual remote oil filters located under the passenger fender. It has a pair of 7″ Halo headlights that are tied into the parking lights. The 4 rear tail lights are ran in conjunction with each other just like the Corvette.
This motor is Bad-ass but now I will be building a Gen V Four bolt main 454 with a Callies 4340 complete rotating assembly, then I will be making my Gen V motor a 496 stroker motor. Then the final piece will be topping it with my Weiand blower.
In this video a make a blade from a-2 tool steel. About 20 total hours of work went into this blade.
