Materials Question About Shear Blades

Heavy shear blades need to be very strong and tough. The shearmakers sell these.

You can buy the same metal as they buy and try to make your own, but it will not be easy as they may well have zone hardened blades. harden too deeply and they may snap off = no fun at all.

here are some llinks to blades, plus the people you bought it from, of course.

Without more information on what material you are using it's hard to say this type or that type is the perfect choice... are you processsing paints, adhesives or cement?

When choosing your blades: depending fo the number of HP you dispose you may choose a different set of cutting or mixing blades. For example if you are cutting titanium dioxide + 1000 kg of ASP 170 in an alkyd resin you will choose a different blade than just wax in toluene, adjusting the speed and the cutting time to avoid excessive heat.

You must take in consideration also the size of the tank, air or electric drive, operating condition, operator's knowledge etc...

These guys are making low shear and high shear blades (custom made). I have done business in the past with them and were able to give me a hand. there is many more or these shearmakers...

I think he refers to the use of blades to cut steel plate, versus the use of high fluid shear mixers to separate aggregated pigments in making ink/paint/glue/rubber etc.

Adding solvent to paint is called 'cutting', as you reduce the concentration of solids ('cut it).

typical mixers in that trade are 3 roll mills, ball mills, banbury mixers, plate impingement mixers, and a host of others that use sets of spinning discs, is sets for special uses.

S-7 would be a better choice. Cutting edge will hold up better, grinds easier.

S-7 is a high shock steel with good ductility. Also has a good heat rating, up to 1000 degrees!

we want something better than S 7 so that edge retention is longer.please advise
