HEAT PROCESSING OF REFRACTORY MARTENSITE STEELS |
| 摘要 |
FIELD: metallurgy.SUBSTANCE: proposed method comprises holding in austenite region at 1060°C for 30-40 min with subsequent air cooling two-step tempering. At first step, low-temperature tempering is performed at 200-350°C while at second step it is performed at 760°C. Every tempering takes 3 hours.EFFECT: higher long-term strength and creep limit.4 tbl, 1 ex |
