| 摘要 |
<p>A high purity martensitic stainless steel having unique resistance to embrittlement in addition to excellent strength, low brittle to ductile transition temperature and good hardening characteristics and consequently having special utility in gas turbine, steam turbine and jet engine applications consisting essentially of, by weight, carbon (0.08-0.15), manganese (0.03-0.13), silicon (0.020-0.10), chromium (11.00-12.50), molybdenum (1.50-2.00), nickel (2.00-3.10), vanadium (0.25-0.40), phosphorus (0.010 max.), sulphur (0.004 max.), nitrogen (0.060 max.), hydrogen (2 ppm max.), oxygen (50 ppm max.), aluminum (0.001-0.025), arsenic (0.0060 max.), antimony (0.0030 max.), tin (0.0050 max.), and iron (balance). <IMAGE></p> |
