X60, X65, X70, X80 medium thick steel plate refers to the following products:

X60 medium thick steel plate. Refers to the pipeline steel, steel grade expression method: L represents the first English letter of the pipeline Line, 415 represents the yield strength value specified by the steel plate, X represents the pipeline steel, 60 represents the yield strength value specified by the steel plate, the unit ksi.
X65 medium thick steel plate. Refers to high-speed pipeline steel, strong deformation resistance, so the stamping performance is not good.
X70 medium thick steel plate. Pipeline steel, used for processing and manufacturing oil and gas pipelines.
X80 medium thick steel plate. It refers to a grade of pipeline steel certified by the American Petroleum Institute, mainly used in the construction of welding oil pipelines, oil racks and other equipment.

X42, X46, X52, X56 steel plate refers to the pipeline steel, which belongs to the wide and thick steel plate of oil and natural gas transmission pipe.

X42, X46, X52, X56 steel plates have the characteristics of high strength, high toughness, good welding performance and corrosion resistance, etc., and are widely used in the manufacture of oil, natural gas and other energy transmission pipelines.
X42, X46, X52, X56 steel plates are described in detail as follows:

X42 steel plate. X indicates pipeline steel, and 42 indicates that the minimum yield strength value of the steel plate is 42 kSi (1ksi=6.895Mpa).
X46 steel plate. X indicates pipeline steel, and 46 indicates that the minimum yield strength value of the steel plate is 46ksi (1ksi=6.895Mpa).
X52 steel plate. X indicates pipeline steel, and 52 indicates that the minimum yield strength value of the steel plate is 52 kSi (1ksi=6.895Mpa).
X56 steel plate. X indicates pipeline steel, and 56 indicates that the minimum yield strength value of the steel plate is 56 kSi (1ksi=6.895Mpa).

The main mechanical properties of pipeline steel include strength, toughness and mechanical properties under environmental media. The tensile strength and yield strength of steel are determined by the chemical composition of steel and rolling process. When selecting materials for gas transmission pipeline, steel with higher yield strength should be selected to reduce the amount of steel. However, the higher the yield strength, the better, because the yield strength is too high will reduce the toughness of the steel.

Gr.bms-x65ms steel plate is a kind of ship steel plate with high strength, high toughness and laminar tear resistance, where "Gr" indicates ship steel, "BMS" indicates the type of steel plate, and "X65MS" indicates the strength level.

Gr.BMS-X65MS steel plate is widely used in shipbuilding, offshore engineering, offshore oil platforms and other fields, its material has excellent welding performance, low temperature impact toughness and corrosion resistance, can meet the strict requirements of ship and offshore engineering structure.

Gr.BMS-X65MS steel plate is usually produced by controlled rolling and controlled cooling process. Through the control of heating, rolling, cooling and other processes of steel plate, the steel plate has excellent mechanical properties and processing properties.
