All OTTP Harcore Time Attack sway bars are made from:
ML-T 6736 Seamless aircraft Grade 4130 Finish condition N Mechanical properties (average) Tensile test (psi) 119289/Yield (psi) 111207/Rockwell B 100
Sourced via Team Tube, from Benteler Steel and Tube, Germany.
Check other vendors for their mechanical properties....
HEAT TREATED ALLOY BARS
These alloys have been quenched and tempered (except e.t.d. 150s rounds which are elevated temperature drawn and 4150 Mod. RS flats and squares under 3 which are normalized and stress relieved) so that strength and hardness is already developed, ready for use. Many hot rolled bars are machine straightened and can be furnished with or without stress relieving. All cold drawn bars are fully stress relieved after drawing so that distortion during machining
is held to a minimum.
4340 QTSR (Nikrome) has a high nickel/chromium content which gives outstanding depth of hardness with high mechanical properties throughout the section — and has the strength (302 BHN min.) and toughness to withstand severe service conditions.
4140/42 QT is a general purpose alloy, low in cost, nominally .95% chromium and .20% molybdenum. Has good hardness ***********, strength, toughness, and ductility. Sizes thru 7'comply with the chemical and mechanical properties of ASTM-A193-B7, ASME SA193 (Latest) B7 and/or MIL-S-1222 (B7). Sizes over 7 conform to ASTM A434.
e.t.d. 150 is made by the elevated temperature drawing process to obtain properties and strengths usually achieved only by quenching and tempering. No heat treating is required — properties are in-the-bar as received. This steel machines faster than heat treated bars and compares favorably with cold drawn 4140 annealed.
4130 QT is a general purpose alloy, with a nominal .30% carbon, .95% chromium and 20% molybdenum. Offers good strength and toughness for moderately stressed parts.

also i dont do any autox or anything...i mainly just have alot of sharpies around where i live(im talking 90's and 180's and the like...would a 1.25 bar be too much for the car or would a 1" be better? im just curious because i dont really know much about these(suspension isnt my thing)
