Product Description

ASTM A193 B7 Alloy Round Bar good technology production hot rolled steel round bar

 

Use of round steel:
Ordinary carbon round steel is used for structures that do not require high tensile strength, such as ordinary construction projects, ordinary standard parts, hot-rolled steel, etc.; high-quality carbon structural steel, which contains low levels of harmful elements sulfur and phosphorus (≤ 0.035%), of which 08, 10, 15, 20, 25 and other grades are low carbon steels, which have good plasticity and are easy to draw, extrude, stamp, forge and weld;Medium carbon round steel, after quenching and tempering, can obtain excellent mechanical properties, and is often used for more important shafts,fasteners, etc.;High carbon round steel to make springs and wear parts;Other alloy round steels, such as 20CrMnTi, are important carburized steels, suitable for important gears, etc. 27SiMn is a high-strength, easy-to-weld steel used where welding is important. 35CrMo, 42CrMo are high-strength steels used for very important parts, such as engine connecting rod screws, cylinder head screws. Heavy duty car tire screws, etc.

Inspection Methods	Tensile testing (1) Tensile test method: GB/T228.1-2010, JISZ2201, JI SZ2241, ASTMA370, 1497, BS18, etc; (2) Bending test method: often use standard test methods have GB/T232-88, YB/T5126-2003, JISZ2248, ASTME290, ROCT14019, etc.
Application	Rebar is widely used in building, bridge, road and other civil engineering construction. From highway, railway, bridge, culvert, tunnel, flood control, dam and other public facilities, to the building foundation, beams, columns, walls, plates, screw steel are indispensable structural materials. With the deepening of China's urbanization, the demand for rebar is strong for infrastructure construction and the booming development of real estate.

 

 

Chemical composition of round steel:
Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel according to chemical composition (i.e. by carbon content).

Low carbon steel: also known as mild steel, carbon content from 0.10% to 0.30% low carbon steel is easy to accept all kinds of processing such as forging, welding and cutting, often used to manufacture chains, rivets, bolts, shafts, etc., because of its high elongation is not easy to break, also used in construction engineering.

Medium carbon steel: 0.25% to 0.60% carbon steel, in addition to carbon can also contain a small amount of manganese (0.70% to 1.20%). Good hot working and cutting performance, poor welding performance. The strength and hardness are higher than low carbon steel, while the plasticity and toughness are lower than low carbon steel. Without heat treatment, directly use hot rolled material, cold drawn material, can also be used after heat treatment. The quenched and tempered medium carbon steel has good comprehensive mechanical properties. The highest hardness that can be achieved is about HRC55(HB538) and σb is 600 ~ 1100MPa. So in a variety of uses of moderate strength level, medium carbon steel is the most widely used, in addition to as a building engineering material, but also a large number of used in the manufacture of various mechanical parts.

High carbon steel: Often called tool steel, with carbon content from 0.60% to 1.70%, can be hardened and tempered. Hammers, crowbars, etc. are made of 0.75% carbon steel; Cutting tools such as drills, taps, reamers, etc. are made from 0.90% to 1.00% carbon steel.
