Low Alloy High Strength HR500LA Automotive Steel Sheets Plates
- John
HR500LA steel sheets and plates, known for their exceptional mechanical properties and versatility, are widely used in automotive, construction, and machinery manufacturing industries. In this blog, we delve into its properties, surface treatments, uses, and more details about HR500LA steel sheet and plate products.
What Is HR500LA Steel?
HR500LA steel is a high-strength low-alloy (HSLA) steel produced using hot rolling. This material is purposefully engineered to provide a blend of excellent tensile strength, reliable weldability, and strong formability. Its tensile strength is at least 500 MPa.
HR500LA steel sheet is rolled at high temperatures, typically above 900°C. This material is often used to make car frames, structural supports, and machine parts that need to be strong and durable.
HR500LA Steel Sheets Dimensions Range
We provide HR500LA steel sheets and plates certified to EN 10149-2, ISO-TS16969, and ISO 9001:2008 standards. Our product dimensions are as follows:
- Thickness: 1.5–20 mm (0.059–0.787 inches)
- Width: 900–2000 mm (35.43–78.74 inches)
- Length: 2000–12000 mm (78.74–472.44 inches)
In addition to steel sheets and plates, we also supply HR500LA steel coils, offering the same high standards of quality. We provide custom-size options for all products to meet your specific project needs, guaranteeing an ideal match for any use.

HR500LA Steel Sheets Machinability
HR500LA steel exhibits good machinability. We can offer a variety of forming and cutting processes for our HR500LA steel sheets, plates, and coils. Available options include laser cutting, bending, stamping, and welding.
This excellent machinability is attributed to their optimized chemical composition and microalloying with elements like niobium (Nb) and titanium (Ti), which refine the grain structure and enhance the material’s mechanical properties without sacrificing ductility.
- Low Carbon Content: Ensures simpler machining and minimizes tool degradation.
- Microalloying Additives: Elements like niobium and titanium improve strength while maintaining formability.
- Hot-Rolled Processing: Produces a material with a consistent hardness and reduced internal stresses, simplifying machining operations.
HR500LA Steel Sheets Surface Treatment
HR500LA steel sheets exhibit moderate corrosion resistance due to their low carbon content and micro alloying elements. However, the lack of additional alloying elements such as chromium (Cr) or nickel (Ni) limits their ability to withstand prolonged exposure to moisture, saline environments, or chemical agents.
In such conditions, surface treatments are necessary to improve corrosion resistance and prolong durability.
Common Surface Treatments:
- Galvanization:
A zinc coating protects the steel from oxidation and rust, making it ideal for outdoor structures and moisture-prone environments.
- Phosphating:
Adds a protective phosphate layer to improve corrosion resistance and serves as a base for paint or coatings, widely used in automotive applications.
- Powder Coating:
Provides a durable and decorative finish, enhancing resistance to scratches and environmental degradation, suitable for exposed or visible components.
HR500LA Steel Sheets Applications
HR500LA steel sheets offer an excellent balance of high strength, formability, and cost-efficiency. While they may require additional coatings for corrosion resistance, their affordability and versatility ensure widespread use in mass production and structural projects.
