QUENCHED AND PARTITIONED HIGH-CARBON STEEL WIRE |
摘要 |
A high-carbon steel wire has as steel composition: a carbon content ranging from 0.40 weight percent to 0.85 weight percent, a silicon content ranging from 1.0 weight percent to 2.0 weight percent, a manganese content ranging from 0.40 weight percent to 1.0 weight percent, and a chromium content ranging from 0.0 weight percent to 1.0 weight percent. The remainder is iron. This steel wire has as metallurgical structure a volume percentage of retained austenite ranging from 4 percent to 20 percent, while the remainder is tempered primary martensite and untempered secondary martensite. The steel wire is obtained by partitioning after quenching. |
