ASTM A48 Grey Iron Casting Parts are widely used for Auto-cars, trains, trucks, vehicle components, mining machinery components, agricultural machinery parts, textile machinery parts, construction machinery parts, etc.
Gray iron castings in ASTM A48 Class 20 are intended for general engineering use where tensile strength is a major consideration.
The grade is equivalent with grey irn GB/T 9439-1988 HT150, DIN 1691 GG15, JIS G5501 FC15, NFA32-101 Ft.15D, BS1452 Gr.150, ISO/R185 Gr.15 in China and other countries.
Chemical Composition:
C:3.0~3.6 S:≤0.12 P:<0.15 Mn:0.6~1.0 Si:1.4~2.0
Please note that this chemical composition is not standard, just from working experience of our iron casting foundry.
Mechanical properties
ASTM A48 Class 20 gray iron has a minimum tensile strength of 20,000 psi (140 MPa). Class 20 has a high carbon equivalent and a ferrite matrix.
