Why Redline?

A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.

With a redline you'll immediately see:

Save Time and Trouble!

With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.

Price

When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

Annotation of standard text ASTM B770-21 :

This specification establishes requirements for copper-beryllium alloy sand castings for general applications and covers Copper Alloy UNS Nos. C81400, C82000, C82200, C82400, C82500, C82510, C82600, C82800, and C96700. The product shall be manufactured by casting and thermal treatment. Castings shall conform to the chemical composition requirements prescribed for copper, nickel, silicon, beryllium, cobalt, chromium, iron, zirconium, tin, and manganese. The standard temper designations include TF00 (cast, solution and precipitation heat treated) and M01 (as sand cast). Requirements for precipitation and solution heat-treatments of castings for the purpose of determining conformance to the specified mechanical properties including tensile strength, yield strength, and elongation are detailed. Special combinations of properties such as increased ductility, electrical conductivity, dimensional accuracy, and endurance life may be obtained by special precipitation heat-treatments. Tension tests shall also meet the mechanical property requirements.
