Surface Grinding 420 Stainless Steel

The 420 stainless was geat to machine plus it is magnetic making it more convenient to surface grind.

Surface grinding 420 stainless steel.

When grinding the internal hole of acid resistant stainless steel resin bonded grinding wheels can help improve the surface quality and avoid burn. There are individual prominent abrasive grains on the working face of the grinding wheels and scratches the working surface before they falling off. Surface hardening of stainless steels grain boundary m 23c 6 boundary of passivity chromium content. 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.

It has not been heat treated yet. Drilling and tapping was also easy and so was grinding. When grinding stainless steel the machined surface is scratched easily which is not allowed in term of the machined surface roughness requirements are high. The causes of scratched.

Sharp edg es the inside of bores and gaps present no limitation to the process 4 11 12 13. After working with the 420 i wished the entire project was 420 stainless and forget the 304. Materials to be treated by low temperature carburising should be in the solution annealed condition.
