Component Specifications

Definition
A steel substrate is a precisely manufactured cold-rolled steel sheet that serves as the foundational component in various industrial applications. It undergoes controlled rolling at room temperature to achieve specific mechanical properties, surface finish, and dimensional accuracy. This component acts as the core material upon which additional layers, coatings, or structures are applied, making it critical for product integrity and performance in sectors like automotive, construction, and appliance manufacturing.
Working Principle
The steel substrate functions by providing a stable, durable base with consistent mechanical properties. Its cold-rolling process enhances strength, hardness, and surface smoothness through plastic deformation below the recrystallization temperature, resulting in a material with low internal stresses and uniform thickness. This allows it to withstand mechanical loads, resist deformation, and serve as an optimal surface for adhesion of coatings or further processing.
Materials
Low-carbon steel (e.g., AISI 1008, 1010), high-strength low-alloy (HSLA) steel, or stainless steel grades, with typical carbon content below 0.25% for formability and weldability.
Technical Parameters
  • Width 600mm to 2000mm
  • Thickness 0.3mm to 3.0mm
  • Yield Strength 140 MPa to 350 MPa
  • Tensile Strength 270 MPa to 550 MPa
  • Surface Roughness Ra 0.8μm to 2.5μm
  • Flatness Tolerance ≤5mm/m
Standards
ISO 3574, ISO 16162, DIN EN 10130, ASTM A1008

Frequently Asked Questions

What is the difference between hot-rolled and cold-rolled steel substrates?

Hot-rolled steel substrates are processed at high temperatures, resulting in a rough surface and lower dimensional accuracy, while cold-rolled substrates are processed at room temperature, offering smoother surfaces, tighter tolerances, and higher strength due to work hardening.

How does steel substrate thickness affect its application?

Thinner substrates (e.g., 0.3-1.0mm) are used for lightweight applications like electronics or packaging, while thicker ones (1.0-3.0mm) provide structural support in automotive panels or machinery, balancing weight, strength, and formability requirements.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
