Stainless Steel Finishing System — Weld Leveling to Final Finish in 3 Easy Steps

Step 1 – Leveling the Weld

Using the following products for weld leveling helps
prepare stainless steel for #3 and #4 finishes.

Recommended Starting Points

NEW!

3M™ Cubitron™ II Fibre Disc 987C

(Grade 60+; 7" diameter)

• Made with 3M precision-shaped

ceramic grain for ultra-fast cut
and exceptional life.

• Includes a grinding aid for cooler

running temperatures.

3M™ Fibre Disc 785C

(Grade 60; 7" diameter)

• Contains 3M™ Ceramic Aluminum

Oxide blend abrasive grain.

• An excellent starting point for

stainless steel and high nickel alloys.

• Includes a grinding aid for cooler
running temperatures.

Work Hint: Use the finest grade of abrasive that gets the job done; finer
grind lines are easier to remove. Align the grind line scratches with the grain
line direction of the original stock. Perpendicular scratches are more difficult
to blend; parallel scratches blend easily during finishing. Use a 7" dia. black
ribbed faceplate to level the weld quickly and leave fine grind lines.

3M Precision-Shaped Grain

Triangular-shaped grain (top) is electrostatically oriented to form sharp
peaks, each acting like individual cutting tools that wear evenly for super
long life and consistency at any grinding pressure.
