Cold Rolled 304 Grade 2B Finish Stainless Steel Coil

Hongwang Holding Group is an enterprise specializes in the production of cold rolled stainless steel, electrical steel , stainless steel coil and sheet finishing products. Cold Rolled Grade 304 2B Finish Stainless Steel Coil refers to a type of stainless steel coil produced through a cold-rolling process, offering specific properties and a distinctive surface finish.In 2019, Hongwang successfully commenced the trial production of its color-coated coil project. This strategic expansion was supported by the installation of a state-of-the-art 1450mm hot and cold annealing and pickling line, which featured an integrated in-line four-stand tandem mill. The project achieved an annual designed production capacity of 700,000 tons, significantly enhancing the company's product portfolio and market competitiveness.

Material: Grade 304 stainless steel is a commonly used austenitic stainless steel known for its excellent corrosion resistance, durability, and versatility.

Manufacturing Process: Cold-rolling involves processing the steel at or near room temperature, which enhances its strength and surface finish.

Finish: The 2B finish is a smooth, matte, and reflective surface achieved through cold rolling, heat treatment, pickling, and light rolling. It is considered the standard mill finish for cold-rolled stainless steel.

Cold Rolled Steel: Preventing Recrystallization

Cold rolling sets itself apart by interrupting the steel's natural recrystallization process. This technique involves allowing the steel to cool completely to room temperature before it is shaped and formed.

Key Advantages:

Superior Strength & Precision: The cold rolling process induces strain hardening, increasing the steel's strength by up to 20% compared to hot-rolled steel. It also exhibits minimal warping, which is critical for high-tolerance, precision parts.

Enhanced Surface Quality: The finished product boasts a smooth, often slightly oily surface that is both visually appealing and pleasant to the touch, frequently eliminating the need for additional finishing.

Advantages of Cold Rolled Stainless Steel Coil

Precision-Perfect Foundation: Experience a flawlessly smooth, ready-to-finish surface with a superior finish (Ra ≤ 0.5µm). Our coils are manufactured with micrometer-level precision (tolerance within ±0.02mm), guaranteeing dimensional stability and eliminating costly rework, setting the stage for your highest-quality products.

Strength That Adapts to Your Vision: Through our controlled cold-working process, we engineer enhanced mechanical properties, achieving a tensile strength range of 700-900 MPa. This unique combination of high strength and exceptional formability allows for complex deep drawing, stamping, and bending without compromising structural integrity.

Built to Endure the Toughest Conditions: With a high chromium content (10.5%-30%), our steel offers exceptional resistance to corrosion and oxidation. Select grades are specifically suited for challenging environments, from marine applications (PREN ≥35) to high-temperature services up to 870°C, ensuring long-term reliability and reducing lifecycle costs.

A Commitment to Sustainable Quality: As a responsible partner, we provide a 100% recyclable product manufactured through processes that reduce energy consumption and CO₂ footprint. This means you can source with confidence, knowing you're choosing a solution that benefits both your project and the planet.

Applications Across Industries

From the sleek, reflective surfaces of architectural elevator panels and curtain walls to the critical components in medical surgical tools and automotive exhaust systems, our cold rolled coil is the trusted material. It is also widely specified for electronics, energy equipment, food packaging, and kitchen supplies, proving its versatility and reliability.
