Plat Amstrong 690QL/1 High Yield Strength Steel Jakarta


Product  : Amstrong® Ultra 690QL plate
Kategori : High Yield Strength Steel for Welded and Weight
Standard: EN 10025-6
Grades   : Amstrong® Ultra 690QL & 690QL1

Equivalent
S690QL, EN 10025-6, EE 690 TIIK4, NFA 36 – 204,

Characteristic
Amstrong® Ultra 690QL is a high strength quenched and tempered steel dedicated for structure and enables to make weight savings thanks to a minimum yield strength of 690 N/mm². Thanks to its exceptional purity rate (very low sulphur and phosphorous contents), and its adapted chemical analysis, the Amstrong® Ultra 690QL steel is easy to shape and to weld.
