Fe-430 steel is a material grade and designation defined in ISO 630 standard. ISO 630 is an international material standard for billet steel for general structural usage. Fe-360C steel can be compares with this type of steel.
Fe-430 steel is a structural billet steel for structural applications.

Fe-430 Steels The Chemical Composition : ISO 630 defines the chemical composition of Fe-430 steels as under:

Maximum percentage of Carbon (C) is 0.20.

Maximum percentage of Manganese (Mn) is not defined.

Maximum percentage of Phosphorous (P) is 0.045.

Maximum percentage of Sulphur (S) is 0.045.

Maximum percentage of Nitrogen (N2) is 0.009.

Remaining is iron (Fe) percentage and with few negligible impurities.

Fe-430 Steels Mechanical Properties : The tensile strength of the Fe-430 Steels is expressed in Newton per millimeters and it must be at-least 430 N/mm2 (MPa) and maximum can be 530 N/mm2 (MPa). The yield strength is minimum 275 N/mm2 (MPa) for less than 16 mm, 265 N/mm2 (MPa) for 16 mm to 40 mm, 255 N/mm2 (MPa) for 40mm to 60mm. The minimum percentage ranges for elongation is 22%.

Fe-430 Steel Dimensional Characteristics : The applicable thickness for this Fe-430 material as defined in the ISO 630 starts from 10 mm to 60 mm.
