ASTM A992 and A572 Dual Certified Steel Beam and Channel. Gnee stocks ASTM A992 (A572 Grade 50) dual certified beams. A992 is the most commonly used structural steel in construction and is used to make I beams, Wide Flange, as well as channels, plates.ASTM A992 steel contains small content of vanadium or columbium, copper, nickel, chrome and molybdenum, all of which greatly improve A992 comprehensive property.
Astm A572 Q345 H I Steel Profiles Iron Beams
Astm A572 q345b i beam are considered to be the most popular forms of structural rods that act as strong columns and do not pose any threat to your large structures.
40CrNiMo hot rolled steel round bars
40CrNiMoA steel is a Chinese alloy steel, has high strength, toughness and good hardenability, and has anti-overheating stability, but has high white point sensitivity, temper brittleness and poor weldability. Preheating is required before welding, and stress relief treatment is required after welding.
Q460D hot rolled steel round bars
GB/T1591 Q460 contains three different steel grades as Q460C,Q460D and Q460E.Structural steel Q460D shall be done impacting test at low temperature minus 20 degree centigrade.Normalised heat treatment suggested to be done for low alloy steel plate Q460D in heavy thickness,Quenched and tempered is also adopt when end users demand.
T8-T10A hot rolled steel round bars
T8, T10 and T12 are carbon tool steels. They are very hard. The Brinell hardness in annealed state is more than 300.Manual saw blade is T12 material, just quenching, hardness is greater.10 and 20 are low carbon, high quality structural steel, very soft, Brinell hardness is less than 155.Therefore, the fitter saw, laborious, the saw is very easy to wear.
10# hot rolled round steel bar
Hot rolled round bar is a strong, tough, ductile, formable and weldable steel material that can be used for numerous types of applications. It also provides a rougher surface and can be easily shaped and formed.
Cr12 hot rolled steel round bars
CR12 round steel refers to a solid long steel with a circular cross section. The specifications are expressed in millimeters of diameter. For example, "50" means round steel with a diameter of 50 mm. Round steel is divided into three types: hot rolled, forged and cold drawn.
GB/T1591 high strength low alloy structural steel grade Q345E owned minimum yield strength at 345Mpa and tensile strength above 470Mpa.When rolling steel plate Q345E,the impacting test shall be done under low temperature at minus 40 centigrade
