Astm A36 Mild Ship Building Carbon Steel Plate

ASTM A36:

American standard carbon structural steel ASTM-A36 in accordance with the American Society for Materials and Testing standards, ASME standard production, is ordinary carbon steel, equivalent to China's Q235, belongs to the American standard general Carbon Steel Plate.

ASTM A36 is suitable for riveted, bolted and welded structures of Bridges and buildings, often used in the machinery industry. ASTM A36 cutting and welding performance is good, in cutting processing, stable performance, cutting deformation small day easy to welding heavy equipment parts manufacturing, metallurgy, chemical industry, flange and other manufacturing industries are widely used.

ASTM A36 Mechanical property:

Ship building plate:

Shipbuilding Steel Plate refers to the thin steel plate and thick steel plate produced from the structural steel specially used in shipbuilding and used in the manufacture of the hull structure of ocean-going, coastal and inland navigation ships. The ship plate must have high strength, good low temperature impact toughness, good welding performance.

Because the service period of Marine engineering equipment is half longer than that of Marine products, and the working environment is harsh, the steel plate used must have the characteristics of high strength, high toughness, fatigue resistance, laminar tear resistance, good weldability and seawater corrosion resistance, etc., and focus on the development of F class high strength and meet the Z performance requirements of the ship plate. The thickness of 6-10mm, the width of more than 3000mm and the thickness of 65-90mm thick ship plate, double phase stainless steel plate, and rack steel and other ultra-high strength Marine engineering steel. Process performance should reach: rolled steel plate Z tear resistance to Z3 level; The tensile strength of steel should reach 780-950MPa, and the yield strength should reach 690-760MPa. Atmospheric corrosion resistance should reach 2-5 times of ordinary steel plate; The corrosion resistance of sea water should be 40%-50% higher than that of high strength shipbuilding board.
