GL Grade DH36GL Grade DH36 shipbuilding steel plate

GL Grade DH36,GL Grade DH36 shipbuilding steel plate,GL DH36 ship plate Normalised and TMCP rolled GL Grade DH36 shipbuilding steel plate owned the higher tensile strength within 490-620 Mpa,and the minimum yield point shall be 355 Mpa.Class DH36 indicates the low temperature impacting test shall be done under minus 20 centigree.Gnee steel exported 500,000 tons higher strength shipbuilding steel materials all over the world especially southeast asia shipyards each year. When delivery shipbuilding steel plates,heat treatment mark would be appear on our each steel plate as steel mark,such as Normalized would be marked as N,TMCP would be marked as TMCP which is short for Thermo-Mechanical Control Process. Besides heat treatment mark on each steel plate,mill quality department would mark on each shipbuilding steel plate,for GL Grade DH36 ship plate,the steel mark should be included as Mill's Logo,Sizes,Steel Grade,Heat Number or Batch number.   Chemical composition of Heat analysis for Shipbuilding steel plate GL Grade DH36 (Max %): C Mn Si P S Al (acid) Nb 0.18 0.90-1.60 0.50 0.035 0.035 ? 0.015 0.02-0.05 Ti V Ni Cu Cr Mo 0.02 0.03--0.10 0.40 0.35 0.20 0.08 Mechanical properties for Shipbuilding steel plate GL Grade DH36: Yield strength (Mpa) Tensile strength (Mpa) Steel Mark 355 490-620 GL/DH36/D36 url:http://www.gneesteels.com
