The effect of grain refining process with 4 times 860 Y 15 min water cooling recycling treatment on mechanical properties of maraging stainless steel 00Crl3Ni7Co5Mo4Ti (/% : 0. 009C
13. 28Cr
7. 37Ni
5. 36Co
3. 59Mo
0. 66Ti) has been studied. Based on the original structure of steel with 1 100 ℃ 1 h solid solution treatment
after 3 ~4 times recycling phase transformation treatment
the grain size of maraging steel refines to 10 μm equiaxed fine grains from original 180 μm. Compared with traditional 1 100 ℃ 1 h solid solution +450 ℃ 9 h aging process
with 1 100℃1 h solid solution +860 °C 15 min water cooling α′↔γ phase transformation +450 ℃ 9 h aging
the yield σ
0.2
of steel increases to 1 560 MPa from 1 420 MPa and the elongation δ increases to 14. 9% from 12. 6%.
