Q345B Q345C Steel Plate, 2–3.5 mm for Defined Armour and Vessel Requirements
Flat steel sheet is described with thickness 2–3.5 mm and an actual width selection of 1251–1500 mm. Length is supplied according to customer requirements.
Specify the exact grade from Q345B, Q345C, Q345D, Q345E, Q390, Q390B and Q390C alternatives. Define the applicable material standard, delivery condition and required inspection documentation before approving a pressure vessel or armour specification.
Armoured, high strength and high pressure wording does not provide ballistic performance, pressure limits or a verified mechanical result. BIS and JIS certificate references require actual documentation for the supplied grade. Skin passing and processing services do not establish service approval or qualified welding, so acceptance must be tied to the intended component specification.
