Automobile Steel HX460LAD Steel Coil | 1.0990- EN 10346
- John
At SteelPro Group, we specialize in providing certified, high-quality steel materials to industries worldwide. In this article, we dive into the details of HX460LAD steel coils—covering their dimensions, manufacturing processes, surface treatments, and diverse applications.
What Is HX460LAD Steel?
HX460LAD steel is a strong, low-alloy steel made with a hot-dip galvanizing process for better rust protection. The “D” means it is designed for shaping and forming. It is cheaper than stainless steel and can be easily welded. It is often used in reinforcements, chassis parts, bumpers, and structural panels.
SteelPro Group supplies automotive steel materials to vehicle OEMs and suppliers worldwide. Our HX460LAD steel coils are always in ample stock and have undergone rigorous quality inspections.

Manufacture and Process of HX460LAD Steel Coils
The production of HX460LAD steel coils follows these precise steps:
- Hot Rolling: The steel is heated and rolled to achieve the required thickness and improve mechanical properties.
- Pickling: Our vertical pickling process combined with a flash nickel layer ensures a clean surface and solves post-coating challenges.
- Cold Rolling: The steel is rolled at room temperature for improved surface quality, strength, and dimensional accuracy.
- Annealing: Fully automated mathematical models precisely control the annealing temperature and rate, ensuring consistent ductility and reduced internal stress.
- Hot-Dip Galvanizing: A zinc coating is applied to the steel for enhanced corrosion resistance.
HX460LAD Steel Coils Surface Treatment
HX460LAD steel needs surface treatment to prevent rust, improve surface quality, and prepare it for further use. Additionally, specialized coatings provide tailored protection and functionality for various applications.
Coatings
| Coating Type | Role | Applications |
| +Z (Zinc) | Provides general corrosion resistance. | Automotive body parts, construction panels. |
| +ZF (Zinc-Iron) | Enhances weldability and wear resistance. | Structural reinforcements, automotive frames. |
| +ZA (Zinc-Aluminum) | Combines corrosion resistance with heat resistance. | High-temperature applications, HVAC systems. |
| +ZM (Zinc-Magnesium) | Offers superior protection in harsh environments. | Marine equipment, industrial machinery. |
| +AZ (Aluminum-Zinc) | Provides excellent corrosion resistance and a reflective surface. | Roofing, cladding, outdoor structures. |
| +AS (Aluminum-Silicon) | Ensures oxidation resistance in high-heat environments. | Exhaust systems, heat exchangers. |
Surface Treatment
- Pickling:
Removes oxides, scale, and impurities to provide a clean surface, ensuring better coating adhesion and a smooth finish. - Oiling:
Adds a light protective oil coating to shield the surface from rust and corrosion during transport and storage. - Phosphating:
Forms a phosphate coating to boost resistance to corrosion and improve paint adherence, making it suitable for components that require painting. - Skin Passing:
Lightly cold rolls the steel after galvanizing to improve surface flatness, correct minor defects, and enhance formability. - Chemical Passivation:
Adds a protective layer post-coating to reduce oxidation and prevent white rust, especially under humid conditions.
