| In the past, 8640
alloy was used in the manufacturing of only the most critical Aerospace and other special
High Strength requirements. Now everyone can have this Superior Quality and Strength, with
the "Off The Shelf" F-911 Hex Cap Screws and at prices comparable to other so
called "Grade 9" bolts. What does 8640 Alloy offer? For starters, up to 50% more
Chromium content and the substantial addition of Nickel, the ingredient that makes this
Alloy tough. With higher Rockwell Hardness that the F-911 specification requires to
achieve an over 190,000 P.S.I. Tensile Strength average, only 8640 Alloy can reach these
lofty goals with superiority. |
