Material Designation and Hardness:The document outlines the material designation for different grades of cast iron, specifying the Brinell hardness (HBW) range for each grade. The grades and their corresponding hardness ranges are:
- EN-GJL-150C: 110 - 180 HBW
- EN-GJL-200C: 140 - 210 HBW
- EN-GJL-250C: 170 - 240 HBW
- EN-GJL-300C: 220 - 290 HBW
Bar Diameter and Tensile Strength:The document provides information on the tensile strength of continuous cast grey cast-iron bars, with a diameter range of 20 - 400 mm. The minimum tensile strength values for different matrix structures are:
- Ferritic/annealed: 80 - 110 MPa
- Ferritic/pearlitic: 115 - 155 MPa
- Pearlitic/ferritic: 155 - 195 MPa
- Predominantly pearlitic: 185 - 220 MPa
Reference Standards:
The document references the standard DS/EN 16482 for the tensile properties of continuous cast grey cast-iron bars.
