AS 2027 Cast Iron is Leesh daily pouring material for our honored Australian customers for mining site and agriculture machinery parts.
Our sand casting process can strictly follow the material requirements to achieve the AS 2027 Cast Iron – Hard and abrasive purpose.
Our sand casting process can strictly follow the material requirements to achieve the AS 2027 Cast Iron – Hard and abrasive purpose.
The types of AS 2027 Cast Iron abrasion-resistant white cast irons covered by this International Standard are:
a) unalloyed or low alloy cast irons;
b) nickel-chromium cast irons covering two general types:
4 % Ni 2 % Cr cast irons;
9 % Cr 5 % Ni cast irons;
c) high chromium cast irons covering five ranges of chromium content:
Cr>11 % to ≤14 %;
Cr>14 % to ≤ 18 %;
Cr>18 % to ≤23 %;
Cr>23 % to ≤ 30 %;
Cr>30 % to ≤ 40 %;
