LR Grade A shipbuilding Steel Description: LR grade A steel is a kind of hot rolled general tensile strength steel. LR steels come 4 grades in ordinary-strength steel for shipbuilding and grade A is the lowest one of them. The LR A grade steel plates have yield strength of 34,100 psi (235 MPa), and ultimate tensile strength of 58,000 - 75,500 psi (400-520 MPa). All the LR/A shipbuilding Steel offered by Katalor Industry can be certificated by Lloyd’s Register of Shipping (LR).

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

LR Grade A Steel Grade Specification: Thickness: 4mm to 260mm, Width: 1200mm to 4000m Length: 3000mm to 18000mm.
