ASTM Grade 60-40-18 vs. ASTM Grade 60-42-10
Both ASTM grade 60-40-18 and ASTM grade 60-42-10 are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing. There are 28 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
For each property being compared, the top bar is ASTM grade 60-40-18 and the bottom bar is ASTM grade 60-42-10.
