ASTM A572 hot rolled structural steel bar is a high strength, low alloy columbium vanadium structural steel. ASTM A572 standard is a specification for structural steel components to specified mechanical properties such as yield strength (YS) of 50,000 PSI (pounds per square inch) for grade 50. These grades are often used in applications where extra strength is desired.
A572 structural steel bars may be supplied as hot rolled round. A typical length for A572 grade 50 strucrural steel round bar is 20′, although many mills have the capacity to roll a variety of lengths depending on the application. A572 grade 50 hot rolled round bars may also be supplied in a wide range of diameters also dependent on the specific application. Some common sizes for A572 grade 50 structural steel round bars are 5/8″, 3/4″, 7/8″, 1″ & 1-1/4″. Many applications require much larger diameters, while some even smaller. A572 steel may be ordered to specific diameters and lengths.
Chemistry:
To achieve mechanical properties, welding capabilities and notch toughness, the chemical composition of A572 hot rolled bars is carefully engineered with controlled levels of carbon, manganese, silicon and the addition of low levels of alloy strengtheners, such as; columbium (Cb), vanadium (V), titanium (Ti), nitrogen (N) or combinations thereof. As an example, A572 grade 50 structural steel bars would have carbon, .23 (max.), manganese, 1.35 (max.) (1.65 max. depending on the carbon), and a combination of the alloying elements.
Applications: A572 grade 50 high strength low alloy steel bar is often used for rivets, bolts or welded structures for bridges or other construction applications.
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.
