Cold rolling is a metalworking process that is typically used to put sheet metal or steel through its paces. In cold rolling, the metal material is processed by rolling at room temperature to change its shape and thickness. Cold rolling is usually performed at a lower temperature than hot rolling, which allows the metal material to maintain a higher level of strength and hardness. Cold rolling usually involves multiple passes through the rolls to gradually reduce the thickness of the metal material and achieve the desired size and surface quality in the final product. Cold rolling produces a smooth, uniform surface and more precise dimensional control for applications that require high precision and excellent surface quality, such as automotive manufacturing, electronic equipment, and construction materials.

Oil & Gas Industry: S32750 Super Duplex piping is an ideal choice for oil and gas extraction, transportation and processing where high strength and corrosion resistance is required.
Chemical industry: For piping systems that transport chemicals in acidic or alkaline media, this corrosion-resistant pipe is essential.
Offshore: In marine environments, where pipes are often exposed to highly chlorinated waters, materials with excellent corrosion resistance are required, and S32750 Super Duplex piping meets this need.
Food Processing Industry: In food processing, piping materials are required that do not contaminate the product and have excellent corrosion resistance and sanitary properties, and S32750 Super Duplex Pipe meets these requirements.
Desalination plants: Piping systems used to process seawater require corrosion-resistant, structurally stable materials, and S32750 Super Duplex is a suitable choice.
Corrosion Resistance: S32750 Super Duplex Steel has excellent corrosion resistance, especially in highly chlorinated environments, and is resistant to corrosion and stress corrosion cracking.
High Strength: This steel has good strength and toughness and maintains its structural stability even under extreme conditions.
Oxidation resistance: The cold rolling process gives the pipe a smoother surface and improves its oxidation resistance for longer service life.
Weldability: Super duplex steels are often weldable, making installation and maintenance easier.
Low Maintenance: Due to its corrosion resistance and long-term durability, pipes made of this steel require less maintenance during service, reducing overall costs.
