Description

There are two kinds of high tensile steel plate for hull according to the yielding strength ; HT32 (32kgf/mm^2) and HT36 (36kgf/mm^2). Many shipyards in Japan have mainly used HT32, but recently started to study the use of HT36 in order to save ship propulsion energy by reducing hull steel weight, etc. Kawasaki Heavy Industries, Ltd. also has carried out various test for HT36 to be used in a 130,000-DWT bulk carrier, and established its welding construction process. This paper describes the results of various labolatory tests for HT36 and production tests in the actual ship.
