JIS G5501 for Grey Iron

JIS G5501 1995 standard is a Japan Standard for grey iron. This standard has stipulated the tensile strength and hardness of grey cast iron. Herein, we listed the main content of this standard for your reference.

Grade of gray and tensile strength of specimen made from castings

Grade	Grade of the old type	Thickness of castings /mm	Compressive strength σ_bc≥/Mpa
FC100	FC10	＞2.5~10 ＞10~20	120 90
FC150	FC15	＞2.5~10 ＞10~20 ＞20~40 ＞40~80 ＞80~150	155 130 110 95 80
FC200	FC20	＞2.5~10 ＞10~20 ＞20~40 ＞40~80 ＞80~150	205 180 155 130 115
