介绍 | CRUCIBLE 17Cr-4Ni SUPPER-X is a version of 17Cr-4Ni which has been modified to substantially improve machinability and other properties. Patented 17Cr-4Ni SUPER-X meets industry specifications for 17Cr-4Ni. The machinability improvement, or up to 45% over conventional solution-treated (condition A) 17 CR-4Ni material, has been achieved by close control of the chemical composition within the standard range CRUCIBLE 17Cr-4Ni SUPER-X shows a significat improvemtn in ductility in all conditions, especially the colution-treated condition. In addition, the steel is markedly tougher than convertional 17Cr-4Ni as measured by Charpy Impact tests. CRUCIBLE 17Cr-4Ni SUPER-X is a precipitation-hardening stainless steel which is capable of high strength and hardness levels after a relatively simple heat-treatment. This grade is martensitic and magnetic in both the solution-treated and precipitation-hardened conditions. It has high resistance to crack propagation, and its corrosion resistance is normally superior to the regular martensitic chromium-type of stainless steel. Because of the single low-temperature (900 to 1150°F) precipitation-hardening heat treatment of this grade, scaling and distortion are virtually eliminated. This enables material to be finish machined to close tolerances prior to heat treatment. |
