High wear factor
WebUltimate tensile strength is the force per unit area required to break a material under tension. It is expressed in pounds per square inch (psi). The force required to pull apart 1 square inch of plastic may range from 1,000 to 50,000 lbs. or higher. Steel and other structural alloys have much higher tensile strengths, such as SS304 at 84 kpsi. WebUnder relatively high loads of 0.648 and 1.10 N in air, metallic wear particles of 1 ~ 100 μm size are generated mostly of α-Fe with some Fe3O4. Specific wear rate wsis in the range …
