| Abstract: | Nickel-free stainless steel powders contained nitrogen were prepared by gas atomization, formed by hot isostatic pressing (HIP), and treated by solution. The HIPed materials have excellent strength, plasticity, and toughness; their tensile strength, yield strength, elongation, area reduction and impact energy are 850 MPa, 505 MPa, 44.5%, 47.5%, and 44 J, respectively. After solution treatment at 1 100℃ for 1 h the plasticity and toughness improve obviously; the elongation, area reduction, and impact energy is 50.0%, 55.5%, and 68 J, respectively. Experimental data show that the prepared nickel-free stainless steel 17Cr10Mn2MoN has better strength and corrosion resistance than 316L stainless steel. |
