1144 Stressproof is the perfect material for long-term machining reliability
Due to the extreme hard work, it is manganese-free carbon steel with optimum tensile qualities. 1144 Stressproof is widely used in high-speed machining of non-ferrous materials.
It is the perfect material for long-term machining reliability – it has a low level of elastic deformity, and its carbon-manganese-free composition means that it’s resistant to corrosion. With a tensile strength of 175,000 psi and yield strength of 130,000 psi, you can be assured that this grade will stand the test of time.
O’Hare Precision Metals can provide a wide range of company-supplied or customer-supplied components and materials. Just like how we can offer you the best 1144/Stressproof Carbon bar stocks and 1144/Stressproof Carbon round bar stocks in O’Hare!
A typical application for StressProof is in industrial, machine, and tooling applications. 1144 steel is a high-strength, high-hardness steel that has been specially treated to relieve tensions in the metal caused by the manufacturing process.
1144 steel rod is used in the manufacture of structural components. That is to say after it has been machined or heat-treated, the 1144 round bar will be less susceptible to warping.
Nuts, arbors, shafts, bolts, gears, pistons, rods, screws, and sleeves are just some of the many applications of 1144/Stressproof Carbon.
