ASTM A108 1008 Introduce
Tensile Strength: The minimum tensile strength of the carbon steel bars as specified by ASTM A108 1008 represents their ability to resist pulling forces without breaking or experiencing deformation.
Yield Strength: ASTM A108 1008 provides guidelines for the minimum yield strength required for these carbon steel bars. The yield strength indicates the stress level at which permanent deformation begins.
Elongation: Elongation measures the ability of the material to stretch before fracturing. ASTM A108 1008 defines the minimum elongation percentage that the bars should exhibit.
Smelting temperature:1789°C - 1563°C
Application:High-quality cold-worked carbon steel bar technical specifications
