新日本钢铁公司最近开发了即使进行强烈冷加工也不带磁性的高强度无磁不锈钢YUS130,已开始出售样品。通过冷加工硬度可达到Hv500以上,而导磁率仍在1.01以下,保持完全的无磁性。以往认为无磁的SUS304和SUS305不锈钢具有如下缺点,即经过强烈冷加工后会在母相中生成铁磁性马氏体相而带有磁性。新开发的YUS130不锈钢的特点是用调整成分等手段抑制了马氏体相的生成。
Nippon Steel Corporation recently developed the high-strength non-magnetic stainless steel YUS130, which is not magnetically fermented even under intense cold working, and has started to sell its samples. Through cold working hardness up to Hv500, while the permeability is still below 1.01, to maintain complete non-magnetic. Historically, the non-magnetic SUS304 and SUS305 stainless steels have the disadvantage that after intense cold working, ferromagnetic martensitic phases are formed in the parent phase and magnetically. The newly developed YUS130 stainless steel is characterized by adjusting the composition and other means inhibit the formation of martensite phase.
