Abstract TIMKEN TBS-9 is a high-carbon, chromium-molybdenum ball-bearing steel that combines high hardenability and low cost. It was designed with metallurgical properties virtually equivalent to those of AISI 52100. TBS-9 is less expensive than the 52100 grade because annealing is simplified. It is produced to the same quality requirements as the 52100 steel. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fatigue. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: SA-363. Producer or source: Timken Company Steel Divison.

High Fatigue

The research about effects of Nb on martensite size and mechanics in B-bearing steel was completed. The results show that both steels have similar martensite due to high hardenability of B element which is responsible for high mechanical properties. However, there are differences in the microstructures between A steel (Nb-containing steel) and the B steel (Ti-containing steel). Microstructural observation of the quenched specimen shows that the formation of fine martensite is dominant in the A Steel than B steel due to Nb element. Martensite size in B-bearing steel was refined by Nb element for high fatigue property and toughness.
