KR Grade A steel plate is common strength shipbuilding plate which is mainly used for built hull of vessels,ship body construction.Ship plate KR Grade A is the Hull structural steel,with it's good toughness properties, higher strength,strong corrosion-resistance,the processing properties,and welding properties.In the steel standard ASTM A131/A131M,offshore steel grade ASTM A131 Grade A is the best equvialent steel grade with KR Grade A.
Our mill test certificate shall be issued according to EN10204 type 3.1 and if need the third party inspection and stamped by them,the Mill test certificate should be issued under format EN10204 type 3.2.For KR Grade A need the inspection by Lloyd's Register ship surveyor after rolling and mill test certificate issued under EN10204 3.2.
