Width | 1000mm-4500mm |
Thickness | 5mm-150mm |
Length | 3000mm-18000mm |
Supply Condition | As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement. |
Impact tested | 52 deg C |
Tempering | Notch toughness can be improved by quenched cooling from hot rolling or normalizing by the supplier. If such a faster cooling rate is agreed upon between purchaser and supplier then the steel is also to be tempered at 1200 F. |
Applications | Used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service. |
