high chrome hardness

  • Alloy Steel Product Guide

    One of the most common chrome moly steels is 4130. 4130 chrome moly is an ideal material for BMX bicycle frames and firearms receivers because of its high tensile strength and high strength-to-weight ratio. Although chrome moly contains chromium, it does .

  • Chrome Bars | Chrome Rods | Associated Steel Corporation

    Chrome hardness is Rockwell "C" 58/60. It is a precision finished chrome plated shaft, minus the induction hardened surface of the shaft substrate. The outer surface of the shaft has high hardness chrome, the sub-surface of the shaft, (under the chrome), is not hardened.

  • High-Alloy White Irons - Total Materia

    High-Alloy White Irons. While low-alloy white iron castings, which have alloy content below 4%, develop hardnesses in the range of 350 to 550 HB, the high-alloy irons range in hardness is from 450 to 800 HB. Specification ASTM A 532 covers the composition and hardness .

  • Metal Profile: Chromium - Properties, History & More

    Chromium metal is most widely recognized for its use in chromium plating (which is often referred to simply as 'chrome'), but its largest use is as an ingredient in stainless steels. Both applications benefit from chromium's hardness, resistance to corrosion, and ability to be polished for a lustrous appearance.

  • Hard Chrome Plating on Aluminum [with graphics]

    How to tell hard chrome from electroless nickel August 28, 2013. Q. Someone has sent me aluminum rollers (tubes 35 mm dia and 280 mm long ) which are plated with something metallic. The measured hardness is ~ 1000 HV 0.1 and thickness about 45 microns. The plating is worn out and I am supposed to provide an alternate plating/coating.

  • Hardness Value of Industrial Hard Chrome Plating

    Industrial hard chrome can be deposited in a rather broad range of hardness depending upon plating bath parameters. Average hardness is in the range of 66 to 70 Rockwell C scale. A deposit of over 0.001-inch thick is essential before chromium will assume its true hardness characteristics when used over unhardened basis metals.

  • Hard Chrome Plating: Hardness vs. Thickness - Finishing

    I would like to know if there is a way to determine what thickness of hard chrome plating will yield a hardness of 69-71 Rockwell C on a substrate of 32-36 Rockwell C. I am attempting to achieve this surface hardness with a thickness of 1.5 mils.
