ASTM A572 Grade 50 – Chemical Composition (Hot Rolled Steel Coil)
| Element | Typical Range (wt%) | Notes |
| Carbon (C) | 0.23 max | Provides strength and hardness |
| Manganese (Mn) | 1.35 max | Increases toughness and strength |
| Phosphorus (P) | 0.04 max | Impurity, must be low to avoid brittleneess |
| Sulfur (S) | 0.05 max | Impurity, low S enhances ductility |
| Silicon (Si) | 0.40 max | Increases strength and oxidation resistance |
| Copper (Cu) | 0.20 min | Optional, enhances resistance to corrosion |
| Niobium (Nb) | 0.02–0.05 | Optional, increases strength (microalloying) |
| Vanadium (V) | 0.01–0.10 | Optional, element for microalloying or none |
| Titanium (Ti) | 0.02–0.05 | Non-obligatory, grain refinement |
ASTM A572 Grade 50 – Mechanical Properties (Hot Rolled Steel Coil)
| Property | Typical Value | Notes |
| Yield Strength (YS) | 345 MPa (50 ksi) min | Stress at the onset of plastic deformation of steel |
| Tensile Strength (TS) | 450–620 MPa (65–90 ksi) | Maximum stress a steel can bear before fracture |
| Elongation | 18–21% | Ductility, gauge length 50 mm or 200 mm, indicates whether the steel is ductile or not |
| Modulus of Elasticity | 200 GPa | Specification for carbon/low - alloy steels |
| Hardness (Brinell) | 130–180 HB | Expected to be hot rolled steel half inch thick or so. |
Notes:
- Hot rolled coil ensures uniform thickness and good surface quality.
- Suitable for structural, construction, fabrication, and industrial applications.
- Weldable and formable, making it versatile for engineering projects.

| Item | Description |
| Packaging Method | Steel coils are securely bundled with steel straps and edge protectors to ensure their stability and prevent deformation during handling and transportation. |
| Surface Protection | Each coil is packaged with cushioning material: an outer layer of waterproof kraft paper and an inner layer of transparent plastic film, with an optional anti-rust coating. |
| Coil Handling | Standard coil orientation is either "eye to wall" or "eye to top." The "eye to wall" orientation is suitable for C-hook lifting, facilitating loading and unloading by cranes and forklifts. |
| Bundle Weight | Weight per coil: 5-25 tons (depending on specifications). Coil width: maximum 1200 mm, maximum 12 meters; thickness: 0.025~5 mm. |
| Loading Method | Heavy-duty steel coil orders can be shipped via container (20GP/40GP/40HQ) or bulk carrier. We provide reliable, long-term, and safe transportation services. |
| Securing Method | The use of wire hooks, wooden wedges, anti-slip mats, and our patented multi-hook system ensures stable and even distribution of cargo during sea transport. |
| Delivery Time | Delivery time is 15-30 working days, depending on order quantity and specifications. |
| Shipping Terms | FOB, CFR, and CIF terms are available upon request. |
| Export Documents | Commercial invoice, packing list, bill of lading, MTC certificate of origin, and certificate of origin are provided. |
| Inspection | Third-party inspection by SGS/BV/Intertek is available before shipment. |
