The grinder can pick up particles of ordinary steel then smear the regular steel into the stainless. The result is a layer of plain steel that will rust on top of your stainless steel. You are better off not grinding the stainless than using a contaminated grinder.
Even a miniscule spark from carbon steel landing on a stainless workpiece can cause contamination problems. Many industries like pharmaceutical and the nuclear sectors require consumables rated as contaminant-free. This means that grinding wheels used on stainless steel must be nearly free less than 0.1% of iron sulfur and chlorine.

Stainless steel is more difficult to grind than carbon steel so it is critical to use the right tools and follow some simple guidelines to get the job done correctly. Choosing the right tool not only increases operator efficiency but it can also reduce rework improve finish and eliminate the risk of cross or general contamination.
We specialise in the grinding of stainless steel plate which is then used in the petrochemical architectural and marine industries. What other work can you do? We can supply Ground Blanks in Mild Steel and Stainless Steel. We specialise in Aluminium grinding eg blocks for injection moulding machines.
The products are available in carbon steel stainless steel A286 alloy steel aluminum and brass with a wide range of finish options including cadmium zinc dull nickel black oxide cadmium type II silver and dry film lube. Both unified and metric sizes are available per AN NAS MS NSA and OEM standards.
The cutting force per unit area of stainless steel can reach 90GPa and the grinding force is 1.5-2.2 times that of 45 steel. High grinding resistance results in high temperature in grinding zone. The l ow thermal conductivity of stainless steel that is about 1/3 of 45 steel makes the instantaneous high temperature of 1000-1500℃ on the workpiece surface.
When grinding the internal hole of acid-resistant stainless steel resin bonded grinding wheels can help improve the surface quality and avoid burn. Hardness. The hardness of grinding wheels for stainless steel should be less harder than grinding wheels for carbon steel in case that the grinding wheels have a good self-sharpening action.

The blade steel is 440C if it is authentic not ATS-34. A real PCC Int& 39;l in this configuration would be very rare. 99.9% of PCC International knives never had stainless handles and never had round open holes on the handles. That& 39;s why the odds are that it is a SETO made knife along the lines of the PCC style.
