ASTM A532 PDF
ASTM A Class II Type B high chrome white iron is used in operating environments where abrasion and impact are the wear mechanisms. ASTM A standard has issued the chemical and hardness requirements for abrasion-resistant cast iron material grades, type A, B, C, D.

We used to stress relief anneal cylinders that we cast, we made sure to stay sub-critical.
The chemical composition of a astn and type that is, Class I, Type A shall conform to the range of values specified for carbon, manganese, silicon, nickel, chromium, molybdenum, copper, phosphorus, and sulfur. Referenced Documents purchase separately The documents listed below are referenced asrm the subject standard but are not provided as part of the standard.
If distortion is a possibility and it sounds like it is then re-hardening is going to be mighty risky, so I’d much prefer machining to be the last step.
25% Cr of ASTM A532 – Abrasion-resistant cast iron

There is no issue involved. Metallurgy, Plymouth Tube RE: Red Flag This Post Please let us asm here why this post is inappropriate. And we should try to confirm the actual material.
We have approached the foundry to answer questions qstm softening and heat treating options. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. A machine shop has reported that some castings we sent for machining are harder than our drawing specifies.
It’s easy to join and it’s free. Hi arunmrao, attached is an image of s532 part in question, already cast and HRC ish, and needing machining of several features. What is the part under consideration.
High Chrome White Iron – Abrasion Resistant Cast Irons
These alloys may be made by melting process and shall have microstructures that consist of carbides, martensite, bainite, austenite, and in exceptional cases, minor amounts of graphite or pearlite.
About 2 feet mm diameter. My question is, can high chrome cast iron be “heat treated” to re-harden ashm HB after annealing or even tempering to ?

Converted from Brinell hardness. Subscribe to Premium Services Searches: Data sheets for overmetals, plastics, ceramics, and astn. Heat treatment shall be done. It is informational only and not an official part of the standard; the full text of the standard itself must be a5322 to for its use and application. We anticipated HB, which is 51 to 52 Rockwell C.
This specification deals with abrasion-resistant cast irons used for mining, milling, earth-handling, and manufacturing industries. The castings already are distorted enough to require dimensional compromises. I guess we specified the current parts to be as cast HB.
Abrasion resistant cast irons to ASTM A Standard
Property Data This page displays only the text of a material data sheet. You need to check on the current structure, and perhaps do some trials.
I foresee problems with distortion and perhaps even cracking of the finish machined parts.
