ASTM A572 Grade 50 – Chemical Composition (Hot Rolled Steel Plate)

Element	Typical Range (wt%)	Notes
Carbon (C)	0.23 max	Provides strength and hardness
Manganese (Mn)	1.35 max	Improves toughness and strength
Phosphorus (P)	0.04 max	Impurity, should be low to avoid brittleness
Sulfur (S)	0.05 max	Impurity, low S improves ductility
Silicon (Si)	0.40 max	Improves strength and oxidation resistance
Copper (Cu)	0.20 min	Optional, improves corrosion resistance
Niobium (Nb)	0.02–0.05	Optional, improves strength (microalloying)
Vanadium (V)	0.01–0.10	Optional, microalloying element
Titanium (Ti)	0.02–0.05	Optional, grain refinement

ASTM A572 Grade 50 – Mechanical Properties (Hot Rolled Steel Plate)

Property	Typical Value	Notes
Yield Strength (YS)	345 MPa (50 ksi) min	Stress at which steel begins to deform plastically
Tensile Strength (TS)	450–620 MPa (65–90 ksi)	Maximum stress steel can withstand before breaking
Elongation	18–21%	Measured over 200 mm or 50 mm gauge length, indicates ductility
Modulus of Elasticity	200 GPa	Standard for carbon/low-alloy steels
Hardness (Brinell)	130–180 HB	Approximate range for hot rolled steel

Notes:

Hot rolled plate ensures uniform thickness and good surface quality.
Suitable for structural, construction, fabrication, and industrial applications.
Weldable and formable, making it versatile for engineering projects.

Packing And Delivery

1️⃣ Bulk Cargo
works for large shipments. The plates are loaded directly onto ships or stacked with anti-slip pads between the base and the plate, wooden wedges or metal wires between plates and surface protection with rain-proof sheets or oil for rust prevention.
Pros: High payload, low cost.
Note: Specialized lifting gear is needed and condensation and surface damage must be avoided during haulage.

2️⃣ Containerized Cargo
Good for medium to small shipments. The plates are packed one by one with waterproofing and anti-rust treatment; a desiccant can be added in the container.
Advantages: Provides superior protection, easy to handle.
Drawbacks: Higher cost, decreased container loading volume.

Stable cooperation with shipping companies such as MSK, MSC, COSCO efficiently logistics service chain, logistics service chain are we to your satisfaction.

We follow the standards of quality management system ISO9001 in all procedure, and have strict control from packaging material purchase to transport vehicle scheduling. This guarantees the H-beams from the factory all the way to the project site, helping you build on a solid foundation for a trouble free project!
