Grade E shipbuilding steel Description

Grade E shipbuilding steel is a kind of hot rolled general tensile strength steel. It comes 4 grades in ordinary-strength steel Grade A, Grade B, Grade E, and Grade E for shipbuilding and Grade A is the lowest one of them. Yield point for all ordinary-strength shipbuilding steels is specified as 34,000 psi (235 MPa), Ultimate tensile strength of ordinary strength alloys is 58,000 - 71,000 psi (400-490 MPa). On certified steels, the plates are marked with the Grade and a preceding Classification Society Mark like AB, AB/B; CCS, CCS B; RINA, RINA A etc.

Grade E shipbuilding steel products are fabricated by Katalor Industry in form of plates, coils, sheets, bars, profiles, bulb flats, and angle steel.

Grade E Shipbuilding Steel Plates Specification:

Thickness: 3-150mm
Width: 1220-4200mm
Length: 5000-17000mm
Notes: coil thickness ≤ 25mm

Grade E Shipbuilding Steel Application

Grade E shipbuilding steel plates are almost exclusively used in the Shipbuilding Industry for the construction of structural parts of ships, barges and marine equipment. Grade E shipbuilding steel also can be used for ship repairing, the offshore oil drilling platform, the platform pipe joints and other components.
Grade E Shipbuilding Steel Heat Analysis

Grade E shipbuilding steel plates in all thicknesses shall be normalized or thermo-mechanical control processed while shapes and bars in all thicknesses shall be heat treated and rolled. Heat analysis of ordinary strength structural steel shall be used to determine the required chemical composition for carbon, manganese, phosphorus, sulfur, nickel, chromium, molybdenum, silicon, and copper.
