Physical and Chemical Properties of Hard Chrome

WebCombining molybdenum, tungsten and chromium steel creates several alloys commonly called "HSS", measuring 63–65 Rockwell "C" hardness. M1 M1 lacks some of the red-hardness properties of M2, but is less susceptible to shock and will flex more. M2 M2 is the "standard" and most widely used industrial HSS. WebThe hardness and durability of a chromium metal surface finish means your parts will last longer even under severe mechanical contact and wear situations. A chrome surface also resists corrosion, making it suitable for use in harsh environments or where other plating materials would wear away, exposing the substrate metal to corrosion attack.
