Gasite® F30G

Gasite® F30G
Basic Specifications
Wear Resistance
Erosion-corrosion resistant white iron alloy.
F30G has a lower resistance to pure wear than regular martensitic
high-chromium white irons such as our Gasite® 28G alloy, but

Microstructure
The microstructure of our F30G alloy consists of approximately
30 percent (by volume) refined carbides in a complex matrix of
austenite, ferrite and/or martensite. This ideal microstructure
offers excellent combined erosion-corrosion resistance and
mechanical properties.
is a proprietary metal (manufacturing process patent #4,638,847).
This alloy contains relatively low carbon and ultra high
chromium. The general chemistry is confidential.
Test Specimens and Certifications
A chemical analysis of each heat is conducted prior to pouring.
For further quality control, we routinely pour test bars from
random heats. After heat treating, the tensile strength and
hardness of the test bars are measured and recorded, and the
casting is checked for uniform hardness at several locations.
Heat Treatment
Thermal treatment is applied to this alloy to achieve ideal casting
properties.
Application
Gasite® 30G alloy is designed for manufacturing pump parts and
other castings for wear-corrosion applications.
