Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise aatm vendors. My question is, can high chrome cast iron be “heat treated” to re-harden to HB after annealing or even tempering to ? Are you an Engineering professional? And we should try to confirm the actual material. Red Flag This Post Please let us know here why this post is inappropriate.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. We anticipated HB, which is 51 to 52 Rockwell C. Metallurgy, Plymouth Tube RE: Converted from Brinell hardness.

We also ask that you refer to MatWeb’s terms of use regarding this information.

Hi arunmrao, attached is an image of the part in question, already cast and HRC ish, and needing machining of several features. You need to check on the current structure, and perhaps do some trials.

The longer, more complicated part calls for the part to be annealed to HB. Register now while it’s still free! The castings already are distorted enough to a352 dimensional compromises. For The shorter, simpler part we called for an as cast hardness of HB.

If distortion is a possibility and it sounds 5a32 it is then re-hardening is going to be mighty risky, so I’d much prefer machining to be the last step. Four 16 mm holes drilled in the body about 12 inches mm from the large end with no flange.

Also, if distortion is a concern, provide some supports.
