EB13053 ASTM A532 Class III Type A 25Cr Cast Iron Valve Liners. Centrifugal casting is essentially liquid forging or pressure casting where molten metal is forced against the mold wall under relatively high pressure. This centrifugal force along with the rapid cooling effect of the chilled mold induces directional solidification across the ...

High chrome white iron can also be softened for drilling and tapping, and then it will be hardened to 56HRC minimum. Hardness test for abrasion resistant cast iron. Ultrasonic inspection for abrasion resistant cast iron. Magsen Foundry proudly offer abrasion resistant cast irons that fully meet the ASTM A532 standard, including
Mar 26, 2020 Martensitic nickel white iron. ASTM A532-I is a class of martensitic nickel white iron. In low-alloy white iron, a matrix is made of pearlite. Pearlite is relatively soft and has low wear resistance. To increase the wear resistance of white cast iron, the Pearlitic matrix is shifted to martensite by introducing Nickel and Chromium in it.
