A36 is the standard construction steel. This is a low carbon steel without heat treat.The hardness is about 150-180 Brinell. A36 is not suitable for any type of target use.
Standard specification for Carbon Structural Steel;
A36 Steel is one of the most common carbon structural steels used in the plate fabrication industry. Its uses vary but it can be riveted, bolted or welded in the construction of bridges and building, and for general structural purposes.
Fabricated Forms:
A36 is produced in a wide variety of forms, including:Plate/Sheet;Structural Shapes;Bar;Sheet. It is generally available in round rod, square bar, rectangle bar, as well as steel shapes such as I-Beams, H-beams, angles, and channels
A36 - hot rolled angle
A36 - hot rolled flat bar
A36 - hot rolled round bar
A36 - hot rolled square bar
A36 - hot rolled tube/pipe
A36 - hot rolled square tube
A36 - steel flat sheet
A569 -hot rolled plate/sheet
A36 steel Chemical Requirements:
Carbon up to .29 maximum depending on thickness.
Manganese range of .80 to 1.20 depending on thickness.
Phosphorous is .04 maximum.
Sulfur is .05 maximum.
Silicon range of .15 to .40 maximum depending on thickness.
Mechanical Requirements:
Yield Strength is 36,000psi minimum.
Tensile Strength can range from 58,000psi to 80,000psi.
Elongation in 50mm test is 23% minimum.
Elongation in 200mm test is 20% minimum.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
