Complete Stainless Steel Solutions for Industry
CNB supplies a full spectrum of austenitic, ferritic, martensitic, and duplex stainless steel sheets and pipes. Our material finds its way into chemical reactors, food processing equipment, marine piping, heat exchangers, and architectural structures. With in‑house slitting, polishing, bending, and pressure testing, we deliver ready‑to‑use components.

Material Grades and Their Environments

• 304/304L: General purpose, good corrosion resistance in most indoor and mild outdoor environments; food and beverage equipment.

• 316L: Addition of molybdenum provides superior pitting resistance; used in chemical, marine, and pharmaceutical applications.

• 310S: High chromium and nickel for oxidation resistance up to 1100°C; furnace parts, heat treatment baskets.

• 2205 Duplex: Twice the yield strength of 304, excellent stress corrosion cracking resistance; heat exchangers, desalination plants.

• 904L: High nickel and molybdenum for extreme acid resistance; chemical processing.

Product Forms

• Sheet/Plate: Cold rolled 0.3‑6.0mm, hot rolled 3.0‑200mm, width up to 2500mm.

• Pipe/Tube: OD 9‑219mm, wall thickness 0.5‑5.0mm. Welded and seamless; round, square, rectangular, U‑tubes.

• Finishing: 2B, BA, No.4, HL, mirror 8K, PVD colors.

Quality Assurance
Every pipe is 100% hydrotested (15kg, 15s) or eddy current tested. Material certificates per EN 10204 3.1 provided.
