Working Principle: How Stainless Steel Sheets Are Made

Cold rolled stainless steel sheets are produced through a precise manufacturing process:

Step 1: Hot Rolling

Steel slabs are heated and rolled to reduce thickness.

Step 2: Annealing & Pickling

The hot rolled coils are heat treated and acid cleaned to remove scale.

Step 3: Cold Rolling

The pickled coils are rolled at room temperature to achieve precise thickness (0.5mm) with excellent surface finish and tight tolerances.

Step 4: Annealing (Again)

Cold rolled coils are annealed to restore ductility and relieve internal stresses.

Step 5: Skin Pass / Leveling

A light rolling pass improves flatness and surface quality.

Step 6: Surface Finishing

Depending on the final application, various finishes (2B, BA, NO.4, 8K, HL) are applied.

Step 7: Slitting & Cutting

Sheets are cut to customer-specified sizes.

Step 8: Inspection

Every batch undergoes rigorous testing:

• Chemical composition analysis

• Mechanical property testing

• Dimensional inspection (±1% tolerance)

• Surface quality assessment

FAQ (Frequently Asked Questions)

Q1: What is the difference between 304, 201, and 430 stainless steel?

A:

• 304: Austenitic, excellent corrosion resistance, non-magnetic. Best for general industrial and food applications.

• 201: Austenitic, good corrosion resistance, lower nickel content (more economical). Suitable for decorative and light industrial use.

• 430: Ferritic, good corrosion resistance, magnetic. Ideal for automotive trim, appliances, and decorative applications.
