2 steel emery function summary
|
high-quality metal alloy steel sand,
the density is high, the blemish is little, the gold
organizes mutually good, the machine function is superior,
having the good tenacity and anti-s broken up.Ability,
reply to use the high depletion of rate low.The sharp
angle form steel sand raises consumedly in spray the
sand process to the tidy up of the metals surface ability
because of having many shapes of sharp angle.
|
Set of Ａ :Degree of hardness>60
HRCs
In order to incise the granite stone to use the steel
sand, this kind of steel sand have:Function stability,
a degree is even and bears to whet sex good etc. characteristics,
was use by a many years of numerous stones material
factory certificate, sharper than the arc sand of the
foreign production, saw to slice the stone material
speed sooner, the stone material saws to slice the plank
noodles are neater.
|
Set of Ｂ :Degree of hardness> the 40-52 HRCs is
new-made to become is the sharp angle form of, usage
process in gradually is whet circle, suited for to do
away with to oxidize the skin and surfaces to tidy up
the homework specially.
|
Set of Ｃ : Degree of hardness>
the 53-60 HRCs is higher than the B set steel sand degree
of hardness, spraying the sand process in the sharp
angle and will lose slowly, special suitable for go
to in addition to oxidizing the skin and surfaces to
tidy up, prepare to handle the homework.
