Don't let your SFM get to high and keep the chipload up. For the 3/8 Drill (depending on the MFG) I'd run it around 300 SFM @ 0.007 IPR. That should drill 1000+ holes in A36 with no problems.

Oct 31, 2006· A36 is an carbon steel. HSS is, at best, the last resort for machining this mat'l. I'd use indexable carbide if you can. Several companies like Iscar or Sandvik can help. If you have to use HSS use slow SFM (40 or less) and medium feed rate of .006 or so for drilling opps. .375 dia. and above.

A36 is mild steel with 60K PSI tensile strength. Agree though, it's the most common steel product produced. The rebar you get at the local home center is ungraded crap,it can be anything. Grade 60 rebar has the same control on makeup as structural A 36.It can be bent,welded and rolled just like structural.Surface Footage Surface Footage Chart and FormulaSurface Footage 127 RPM SFM X 3.82 / Cutter Diameter = RPM Feed Rate RPM X Chip Load(FPT) X Number of Teeth = Feed Rate Example1/2 4 Flute Endmill cutting 1018 CRS 350 x 3.82 / .500 = 2674 RPM 2674 x .002 x 4 = 21.4 in/min FPT = Feed Per ToothSFM for taps? Practical MachinistSep 15, 2011· Here are some guidelines for Mild Steel like 1018. The less threads per inch, the lower the SFM you should use for obvious reasons. For a rough thread like 7TPI, use 30 SFM. So for a .5" thread, figure30 times 4/ .5= 240 RPM, As the TPI go higher, use a little more SFM, like 40 50.

A36 Steel Equivalent materials. ASTM A36 is said to be same as EN S275 steel plate. A36 steel is a very low carbon steel that blends great strength with form ability. It can be safely welded with minimum caution. This structural steel plate can be galvanized to give enhanced corrosion resistance which ensures superior quality.ASTM A36 Steel Properties, Modulus of Elasticity, Yield ASTM A36 Steel. ASTM A36 steel is one of the most widely used carbon structural steels, although the carbon content of A36 material is maximum 0.29%, it is considered to be the mild steel (content of carbon 0.25%).. A36 mild steel is often compared to AISI 1018, A36 carbon steel is commonly hot rolled, while 1018 steel is commonly cold rolled..

Calculate the RPM setting to perform the drilling and reaming operations. Cutting Speed = 40 (fpm) Diameter of Cutter = 0.3701 (G drill) Half the speed for reaming would be = 432 / 2 = 216 RPM for reaming.

Feed should be 0.5 X Suggested Value.Speeds and Feeds Charts Carbide End Mill StoreNow choose the right surface feet per minute (SFM) or surface meters per minute (SMM) Use the SFM and the diameter of the mill to calculate the RPM of your machine. Use the RPM, IPT, CLF and the number of flutes to calculate the feed rate or IPM. If you want to be conservative, choose a slightly lower SFM, but always choose the recommended FPT.

ium Aluminum Nitride (TiAIN) (4500 HV)* ALTiN/TiAIN coating is great choice in machining stainless steels (All) at any speed. For semi dry to dry cutting of most steels, high nickel alloys, stainless steel and cast iron. However, the end user still needs to be cautious to not exceed the limitations of the high speed steel. * Coating hardness is measured in HV (hardness in ASTM A36 / A36M 19 Standard Specification for Carbon A36 / A36M 19 Standard Specification for Carbon Structural Steel shapes~ welded construction~ bolted construction~ riveted construction~ ~ steel plates~ steel bars~
