MP35N® NACE Nickel Cobalt Alloy is a Multiphase® cobalt nickel-based superalloy, consisting of 35% Nickel and 35% Cobalt. MP35N NACE Nickel Cobalt Alloy is produced using a 2-step melting process, the first step is a vacuum induction melted (VIM), this is then followed by vacuum arc remelted (VAR). This 2-step melt process ensures superior cleanliness and minimizes non-metallic inclusions and residual elements (such as carbon), that have deleterious effects on mechanicals and corrosion resistance. MP35N NACE Nickel Cobalt Alloy is produced specifically for use in sour gas (H₂S) service. It is produced by aging, to restrict hardness and limit the susceptibility to cracking in these environments.

There is also data to demonstrate that casting processes which solidify directionally (centrifugal, for example) lead to improvements in rupture strength and thermal fatigue resistance.

Specialty Steel Supply makes all reasonable efforts to ensure the accuracy and correctness of the data found on this website and the associated documents but makes no representations or warranties as to the data’s accuracy, correctness or reliability. All data are for general information only and not for providing design advice. It is the responsibility of the user to test specific alloys under actual service conditions to determine their suitability for a particular purpose.

The use of these two settings in conjunction with the Dynamic toolpath motion, you will increase the metal removal rate of the toolpath which also reduces the overall cycle time.

Due to the high chromium content (25% – 30% for the grades listed below) cobalt-based alloys provide superior corrosion resistance at high temperatures. The materials are more weldable than nickel-based alternatives. While not as strong as nickel alloys at lower temperatures, above about 1700°F / 930°C cobalt alloys show higher strength. Nickel melts at 2651°F / 1455°C while cobalt melts at 2723°F / 1495°C.

Both RCTF and HEM are effected by the stepover percentage used in the toolpath. When using HEM, you will be limited to only a few selections for the stepover percentage whereas with RCTF, you can define any value you want.

MP35N Nickel Cobalt Alloy is produced using a 2-step melting process, the first step is a vacuum induction melted (VIM), this is then followed by vacuum arc remelted (VAR). This 2-step melt process ensures superior cleanliness and minimizes non-metallic inclusions and residual elements (such as carbon), that have deleterious effects on mechanicals and corrosion resistance. MP35N Nickel Cobalt Alloy can be aged to increase mechanical properties beyond those of stainless and nickel alloys, without sacrificing corrosion resistance. MP35N Nickel Cobalt Alloy can be supplied per AMS 5844 (Sol Treated and Cold Worked), and can then be age hardened to increase mechanical properties.

HEM Factor - Adjusts the ISCAR tool's feed rate and spindle speed values to achieve maximum speed and efficiency. Enter a value in the field or use the slider positioned directly above the field to adjust it. You can enter a value from 1 up to 5, depending on the selected machine and tool configuration. Mastercam displays the corresponding feed rate and spindle speed values below the field. When you enter the maximum HEM Factor allowed by the machine and tool configuration, Mastercam displays a message marked with an asterisk and marks the threshold value in the same manner.

RCTF - When selected, Mastercam applies radial chip thinning calculations to the toolpath. This option is also automatically applied when the ISCAR HEM checkbox is selected. The following toolpaths are supported: All 2D High Speed toolpaths, Face, Pocket, Slot Mill, Horizontal Area, Dynamic OptiRough, Area Roughing, and Circle Mill.

ISCAR HEM - Select to activate the ISCAR HEM (High Efficiency Machining) options. By selecting this option, the RCTF (radial chip thinning factor) option is automatically applied. This field display only when an ISCAR CHATTERFREE tool is selected for a Dynamic milling or Dynamic OptiRough toolpath.

Cobalt based metals are alloyed with chrome, nickel, and tungsten. Due to the high cost of these alloys, they are used where severe conditions prevail and require high temperature strength and hardness, excellent wear, galling, corrosion, and/or erosion resistance.

When trying to push cutters to their limits, some often get caught up in high feedrates and spindle speeds. These make for great stories but don't show overall efficiency. For this you must calculate the MRR, Metal Removal Rate, of the toolpath. It's a fairly simple calculation...
