SAE/AISI/ASTM 1020 Channel steel/angle steel/ H-beam/ I-beam

SAE/AISI/ASTM 1020 Channel steel/angle steel/ H-beam/ I-beam,very little quenching, no temper brittleness. Cold deformation crack-prone high plasticity, usually for bending, welding performance calender, curved edges and hammer arch and other processing, and the contact arc welding, gas welding small thickness, shape demanding or complex shape of the workpiece. Cutting of cold drawn annealed or normalized condition than the state is good, generally used to make large discontinuity toughness requirements.

SAE/AISI/ASTM 1020 Channel steel/angle steel/ H-beam/I-beam Chemical Requirements:

Material	C %	Mn %	P %	S %	Other %
ASTM 1020	0.18～0.23	0.30～0.60	≤0.040	≤0.050	_
AISI 1020	0.17～0.23	0.30～0.60	≤0.040	≤0.050	_
SAE 1020	0.18～0.23	0.30～0.60	≤0.040	≤0.050	_

The Mechanical Properties of SAE/AISI/ASTM 1020 Channel steel/angle steel/ H-beam/ I-beam as follows:

Material	Tensile Strength (Mpa)	Yield Strength (Mpa)	Elongation (%)	Hardness (HB)
ASTM 1020	≥410(42) Mpa	≥245(25) Mpa	≥25 (％)	≤156HB
AISI 1020	394.7 Mpa	294.8Mpa	36.5(％)	111HB
SAE 1020	650- 880MPa	350 - 550	8 - 25(％)	111HB

SAE/AISI/ASTM 1020 channel steel genus and construction machinery with carbon steel, the steel complex section steel, its cross-sectional shape of the groove shape. Channel mainly used for building structure, curtain wall engineering, machinery, equipment and vehicle manufacturing. In use required to have good welding, riveting performance and mechanical properties. Raw billet production channel for the carbon content of not more than 0.25% carbon steel or low alloy steel billets. Finished channel after hot forming, hot-rolled or normalizing the status of delivery.

SAE/AISI/ASTM 1020 angle steel the case of with carbon steel construction, angle steel is a simple cross-section steel, mainly for the metal frame member and factories and so on. In use requires good weldability, plastic deformation and mechanical strength. Angle steel billet production of raw materials for the low-carbon square billet, hot-rolled steel angle finished forming, normalizing or hot-rolled state delivery.

SAE/AISI/ASTM 1020 H-beam commonly require large portion bearing capacity, stability, good cross section of large buildings (such as factories, high-rise buildings, etc.), as well as bridges, ships, lifting the transport machinery, equipment foundation, frame, foundation piles.

Its features are as follows:

◆ flange width and lateral stiffness.
◆ bending ability, about 5% -10% over the beam.
◆ two surfaces parallel to each other so that the connecting flanges, processing, and easy to install.
◆ Compared with the welding beam, low-cost, high-precision, low residual stress, without expensive welding materials and weld inspection, saving steel production costs by about 30%.
◆ the same cross-sectional load. Hot-rolled steel H lighter than conventional steel 15% -20%.
◆ H-beam processed into a T-shaped steel, castellated beams may be combined to form various cross-sectional forms, engineering design and production to meet the great demand.

SAE/AISI/ASTM 1020 I-beam whether ordinary steel or light, since the cross-sectional dimensions are relatively high, narrow, so the cross-sectional moment of inertia of the spindle larger difference between two, it can only be directly used in its web plane that is bent member or a composition lattice force member. For axial compression members or perpendicular to the plane of the web as well as curved components are not appropriate, which it has significant limitations range of applications.

SAE/AISI/ASTM 1020 delivery status:

Hot-rolled forming, normalizing , hot-rolled state
