______________________________________________________________ Our forged spindles, hubs and drive plates are virtually bulletproof. All are forged from 4140 steel. Compare that with some of the junk out there. Don't risk your car or your life with inferior parts. Why We Use Forging: Directional Strength: The forging process produces directional alignment (grain flow) for important directional properties of strength, ductility and resistance to impact and fatigue. Impact Strength: Through proper grain flow orientation; the forging process can develop the maximum impact strength and fatigue resistance possible in a metal. Structural Integrity: As
is well known, a forging's structural reliability is exceptional
compared to other metalworking processes. There are no internal gas
pockets or voids that may cause unexpected failure under conditions of
high stress or impact. Heat Treating: Rockwell 31- 35 C Scale Hardness is used through out. Tensile Strength 181,000 - 1000 lb / in. Yield Strength 165,000 - 1000 lb / in. (25% stronger than parts that check Rockwell 25 C Scale). Note: Cambered drive plates are heat treated to 52 - 55 on the Rockwell C Scale. Some manufacturers make their parts from bar stock or billet steel and also use lower heat treatment standards (lower Rockwell Hardness) so they may be easier to machine. Conclusion: Forging is not the least expensive method but it is the best. When looking for hubs, axles, spindles and similar, don't be fooled by low pricing that may indicate an inferior method of manufacturing. |
