3CR12 Stainless Steel Cold Rolled Plate

If you are looking for a cost-effective 3CR12 stainless steel cold rolled plate, we offer high-quality products that meet standards such as ASTM A240, EN 10088, and SANS 651 (3CR12) to meet the needs of industrial and structural applications.

 

What is a 3CR12 Stainless Steel Cold Rolled Plate?

3CR12 cold-rolled stainless steel sheet is a versatile and highly cost-effective 12% chromium utility-grade ferritic stainless steel (typically designated as 1.4003 or 41003). This material combines moderate corrosion resistance with high strength, making it a durable alternative to carbon steel or coated steel in industrial environments. It is particularly well-suited for structural components and wear-resistant applications.

 

We supply 3CR12 stainless steel plates in thicknesses of 0.5mm–6mm and widths of 1000mm–2000mm. Product forms include flat sheets, coils, and cut sheets to length. Surface treatments include 2B, BA, and No.4. Through cold rolling, annealing, and leveling processes, we ensure high flatness, stable dimensional accuracy, and improved surface finish. Its yield strength is approximately ≥350MPa, and its wear resistance is superior to 304 stainless steel, making it suitable for environments from -20℃ to 300℃.

What is the difference between 3CR12 and 304 stainless steel?

The main difference between 3CR12 and 304 stainless steel lies in their composition and corrosion resistance: 304 is a non-magnetic austenitic stainless steel (containing 18% chromium/8% nickel) with extremely high corrosion resistance, suitable for various general applications. 3CR12, on the other hand, is an economical and magnetic 12% chromium ferritic "practical" steel; compared to 304 stainless steel, it is more competitively priced and particularly suitable for mining equipment, conveying systems, wastewater treatment, vehicle manufacturing, and building structures. 

 

Specification Range:

Cold-Rolled Thickness: Typically ranges from 0.5 mm to 3.0 mm. Thicknesses exceeding 3.0 mm are generally processed using the hot-rolled (No. 1) method.
Width: Common widths include 1000 mm, 1219 mm, and 1500 mm.
Lead Time: Typically 45–60 days. If mass production is currently underway, the lead time may be shortened to approximately 30 days.

Packaging

Surface Protection:Protective Film (PVC/PE Coating): Upon customer request, single-sided or double-sided protective films (e.g., blue film, black-and-white film) can be applied to prevent scratches during stamping and processing.
Interleaving Paper: Paper is placed between sheets to prevent surface damage caused by friction (commonly used for 2B finishes).
Strapping Standards:
Bottom Support: Reinforced, fumigated wooden pallets or steel pallets must be used. Given the high density of stainless steel, the load capacity per pallet is typically set at 2–3 tons.
