Shipbuilding use GL grade A steel plate properties
Posted:2019-10-17 15:58:02
GL grade A steel plate is common strength shipbuilding plate which is mainly used to build hull of vessels, ship body construction. Normally when rolling, air rolled and control rolled is OK for shipbuilding use GL grade A steel plate with the thickness equal and below 40mm. And for thickness above 40 millimeters, normalised or TMCP heat treatment would improve shipbuilding use GL grade A steel plate strength in yield and tensile points.
Shipbuilding use GL grade A steel plate properties:
GL grade A | Tensile Strength(MPa) | Yield Strength(MPa) | % Elongation in 2 in.(50mm) min | Impacting Test Temperature(°C) |
400-520 | 235 | 22 | 20 |
Shipbuilding use GL grade A steel plate is mainly used to shipbuilding projects and ocean offshore structural projects such as manufacturing hull, maritime oil extraction drilling platform, platform tube junction and other structural components.
