What is LR grade E multihull steel equivalent IS standard grade

TMCP process is an indispensable technology for our production of low alloy high strength wide and LR grade E multihull steel thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy LR grade E multihull steel and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.

Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, LR grade E multihull steel included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.
