17-4PH Ibikoresho
17-4PH ni chromium-nikel-umuringa wimvura ikomera martensitike idafite ibyuma.Uru rwego rwibyuma bitagira umwanda bifite imiterere nkimbaraga nyinshi, gukomera no kurwanya ruswa.Nyuma yo kuvura ubushyuhe, imiterere yubukorikori bwibicuruzwa biratunganye, kandi imbaraga zo guhonyora zishobora kugera kuri 1100-1300MPa (160-190ksi).Uru rwego ntirushobora gukoreshwa ku bushyuhe buri hejuru ya 300 ° C (572 ° F) cyangwa hasi cyane.Ifite ruswa irwanya ikirere hamwe na acide acide cyangwa umunyu.Kurwanya kwangirika kwayo kugereranywa na 304. Magnetic.
