Metric equivalent sieve sizes were added to Table 2.1. SCOPE1.1 FormThis
6、 specification covers a manganese alloy in the form of powder, preforms and a viscous mixture (paste) of the powder in a suitable binder.1.2 ApplicationThis filler metal has been used typically for joining corrosion and heat resistant steels and alloys where good ductility andmoderate heat resistanc
7、e are required, but usage is not limited to such applications.2. APPLICABLE DOCUMENTSThe issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless
8、 a specific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply.2.1 ASTM PublicationsAvailable from ASTM International, 100 Barr Harbor Drive, P.O.
