9 CHROME, HARD B-20 GOOD MARK CHROMIUM (ALUMINUM OXIDE & CHLORIDE) MSC#1 FOUR SHORT DWELLS USE AMPLE ELECTROLYTE. WAIT APPROXIMATELY 30 SECONDS BEFORE NEUTRALIZING. COBALT ALLOY - STELLITE F-10 or F SECOND DWELL TIME SAND BLASTED SURFES SHOULD HAVE LIGHT OIL FILM REMOVED BEFORE MARKING. THIS WILL IMPROVE STENCIL LIFE. COPPER ALLOY/NICKEL PHOSPHORUS PLATING F-30 COPPER NICKEL ZINC ALLOY F-20

10 COPPER B-20 or COPPER ON STEEL F-60, B-10 or B SECOND DWELL TIME COROBAN 18% ZINC-NICKEL MSC#1, MSC#5 or MSC#41 DICHROMATE & DICHROMATE GOLD CLEAR MSC#1, MSC#5 TWO SECOND DWELL TIME THIS MARKS VERY QUICKLY. DO NOT OVER DWELL. CLEAR MARK WILL RUB OFF. DICHROMATE PHOSPHORUS SILVER MSC#5

12 GALVANIZED TOOL STEEL MSC#22 MARK HOLDS HASTELLOYS F-20, F-10 HEAT TREATED (DARK SURFES) F-10 INCONEL #59CL, MSC#4, F-10 or C-10 or TWO DWELLS, 3 SECONDS EH KALIDE (COATING) MSC#1 or FOUR DWELLS, 8 SECONDS EH BE SURE TO MAKE SHORT DWELLS, APPROXIMATELY ½ SECOND EH

13 KALIDE (COATING) B-70 SHORT DWELLS, 1-1/2 2 SECONDS EH MONEL METALS MSC#4, MSC#1, C-10, D-12, #91NR, MSC#22 FOR MARK, FOR CLEAR MARK NICKEL ALLOYS MSC#32, MSC#7, MSC#1, C-10, MSC#4, MSC#17 FOR MARK, FOR CLEAR MARK THE PLATING PROCESS CAN CAUSE SOME NICKEL PLATING TO MARK WELL, OTHERS TO MARK VERY POORLY. ON THE DIFFICULT PLATING, TRY, B, 8 VOLTS FOR 1 SECOND. NICKEL PLATING MSC#2 (GRID MARKING: F-40) THREE DWELLS, 3 SECONDS EH LEAVES A BEAUTIFUL MARK NICKEL PLATING MSC#6 FIVE DWELLS, 3 SECONDS EH THIS ELECTROLYTE MAKES THE BEST MARK ON NICKEL PLATING. BE SURE NOT TO GO ANY HIGHER ON THE VOLTAGE, AS THIS CREATES TOO MUCH HEAT AND CAUSES THE MARK TO BLUR.

14 NITRITE CLEAR D-12 1 DWELL, 15 SECONDS NITRITE #353 1 DWELL, 3 SECONDS LEAVES A GOOD MARK. NITRITE B-5, MSC#1 TWO DWELLS, 3 SECONDS EH PHOSPHATE F-40 ONE DWELL, 30 SECONDS RUB MARK BRISKLY AFTER ETCHING TO REMOVE OXIDES. LEAVES A VERY GOOD MARK. SILVER PLATING B-10, B-20 or MSC#8 TWO DWELLS, 2 SECONDS EH LEAVES A GOOD MARK. BY SWITCHING THE POWER UNIT TO RATHER THAN, YOU CAN HIEVE A MARK.

15 STAINLESS STEEL 300 SERIES MSC#41, MSC#42, MSC#40, D-12, C-10, MSC#1, MSC#7, #91NR C, 11 VOLTS or ONE OR TWO 2 SECOND DWELLS ALL OF THESE ELECTROLYTES WILL MAKE A NICE MARK. D-12 IS A MORE AGGRESSIVE ELECTROLYTE AND CAN BE USED ON OXIDE, HELPING TO REDUCE ELECTROLYTE INVENTORY. #91NR S Ph IS VERY HIGH, 8.5, SO THIS HELPS TO PREVENT RUST. STAINLESS STEEL 400 SERIES MSC#40, MSC#41, MSC#42, MSC#4, MSC#1, MSC#7, C-10, D-12, #353, F-30, F-60 TWO 2-SECOND DWELLS BY SWITCHING THE POWER UNIT TO, YOU CAN HIEVE A CLEAR MARK. STEEL, TOOL HIGH ALLOY MSC#41, MSC#42, MSC#40, MSC#2, MSC#4, MSC#1, F-30, F-10, D-12, F SECOND DWELL TIME ALL OF THE ABOVE ELECTROLYTES WILL PRODUCE GOOD QUALITY MARKS. HOWEVER, F-10 MAY HELP PREVENT STENCILS FROM CLOGGING SO QUICKLY. STEEL, HARDENED D-2 (BORON CARBIDE NITRATE) MSC#4 TWO 3-SECOND DWELLS

16 STEEL, MILD AND LOW CARBON MSC#41, MSC#42, MSC#2, F-10, F-20, F-50 STELLITE F-40, D-12 4 SECOND DWELL TIME TOOL STEEL D-12 C, 11 VOLTS or MAKES A VERY GOOD MARK. IF VOLTAGE IS SET HIGHER THAN 14 VOLTS, MARKS MAY BLUR AS THIS IS AN AGGRESSIVE ELECTROLYTE AND MARKS QUICKLY. TOOL STEEL CARBON SAW STEEL B-20, MSC#8, B-10 TWO 2-SECOND DWELLS DEPRESSING THE BUTTON WILL PRODUCE A CLEAR MARK. BE SURE TO NEUTRALIZE WELL AND USE A RUST INHIBITOR AFTER THE NEUTRALIZER HAS HAD TIME TO DRY. THIS ALLOY TENDS TO RUST EASILY IF NOT NEUTRALIZED PROPERLY.

17 TOOL STEEL WITH TUFF DRIVE COATING TFHV800 MSC#5 SIX 4-SECOND DWELLS STENCILS TEND TO CLOG EASILY WHEN MARKING THIS ALLOY. BE SURE TO CHANGE PADS AND STENCILS FREQUENTLY. BECAUSE OF THE TIME INVOLVED TO MARK THIS ALLOY, WE SUGGEST NOT AUTOMATING THE MARKING OF THIS ALLOY THROUGH ELECTRO-CHEMICAL ETCHING. THIS MUST REMAIN A MANUAL MARKING PROCESS. TIN ALLOY D-12, B-20, F-10 TWO 2-SECOND DWELLS DEPRESSING THE BUTTON WILL PRODUCE A CLEAR MARK. TIN ELECTROPLATE OR HOT DIP D-12, MSC#22, MSC#5, F-20, B-10 TWO 2-SECOND DWELLS DEPRESSING THE BUTON WILL PRODUCE A CLEAR MARK. TITANIUM COATING F-40, MSC#41, MSC#42, D-12, MSC#32 TWO 1 2 SECOND DWELLS

18 TITANIUM ALLOYS T-10, C-10, D-12, B-10, #59CL, MSC#22, MSC#4 2 3 SECOND DWELL DEPRESSING THE BUTTON WILL PRODUCE A CLEAR MARK. TITANIUM GOLD COAT MSC#2, D-12 TWO 4-SECOND DWELLS TITANIUM NITRITE F-10 TWO 2 3 SECOND DWELLS VAPOR BLAST OR SAND BLAST F-50 TWO 3 SECOND DWELLS IT IS ADVISED TO USE DURA-FAB STENCILS WHEN MARKING.
