Alloy Selector Guide - Engineered Products

1 Alloy Selector Guide Revised 2013 BEP - Bradken Energy Products Alloy Guide 2013 Tacoma, Washington; Chehalis, Washington; London, Ontario Page 1 Introduction The BEP A lloy Selector Guide presents ASTM Specifications in numerical order to facilitate quick reference and tentative material selection. It is impossible to cover each specification in detail. The following pages are brief descriptions of the salient features of each specification.

2 ASTM specifications can be purchased from BEP, Bradken Energy Products , consists of Bradken-Tacoma (formerly known as Atlas Foundry and Atlas Castings and Technology), Bradken Chehalis, and Bradken London (formerly known as AG Anderson). These facilities produce castings from a wide variation of materials, especially carbon steel, low Alloy steel, stainless steel, and nickel base alloys . The London facility also produces some cast iron grades. This Guide reflects requirements of the latest ASTM Standard: Volume , Ferrous Castings; Ferroalloys.

3 This Selector also includes other alloys not included in ASTM that are cast by Bradken-Tacoma, alloys for military and offshore applications. From engineering to the finished casting product, BEP helps to define and meet every casting requirement presented by its customers. Chehalis and London melt using induction furnaces. Tacoma melts metal using basic arc furnaces and AOD refining. Tacoma s AOD (Argon, Oxygen, and Decarburization) refining process creates clean metal that can have exceptional properties.
