Manufacturing Process Of Lean Duplex 2101 Plates

Reheating Furnace

Reheating furnaces are used in hot rolling mills to heat the steel stock to the rolling temperatures.

Scale Breaker

Slab moves first through a scale breaker, which is a two-high rolling mill with vertical rolls that loosens the furnace scale and removes it with high-pressure water jets.

Finish Rolling

The last stage of the rolling process is cold rolling,


Cooling or Quenching is a process of cooling a metal at a rapid rate.

Skin Pass Mill

This produces high-gloss surfaces and achieves the desired mechanical strip properties such as deep-drawing strength.

Marking & Packing

Proper packaging and labeling not only makes the final product look attractive but also save a huge amount of money by saving the product from wrong handling.

What Are Lean Duplex 2101 Plates?

Lean Duplex 2101 Plates are stainless steel plates distinguished by their exceptional corrosion resistance and high strength, belonging to the duplex family with both austenitic and ferritic phases present for balance. As stress corrosion cracking resistance is one of their major features, Lean Duplex 2101 plates find use across industries including chemical processing, marine environments and oil and gas extraction industries.

Advantages of Lean Duplex 2101 Plates

Corrosion Resistance: Lean Duplex 2101 excels at corrosion resistance in environments prone to chloride-induced stress corrosion cracking - ideal for marine environments, chemical processing plants and other potentially hostile conditions. This makes it suitable for use in harsh conditions like chemical manufacturing processes or even extreme temperatures such as those found at chemical processing plants and chemical storage depots.

Strength: Lean Duplex 2101 stands out as being significantly stronger compared to austenitic stainless steels, permitting thinner plate thicknesses without compromise in structural integrity - offering cost savings both during fabrication processes as well as material usage costs.

Cost-Effectiveness: Due to its lean alloying composition, Lean Duplex 2101 tends to be more cost-effective compared to other duplex stainless steels with higher alloy content. This makes it an attractive option for applications where a balance between performance and cost is desired.

Weldability: Lean Duplex 2101 can easily be weld using familiar welding techniques like shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW), making fabrication and construction processes simpler while streamlining assembly of structures or components.

Formability: Lean Duplex 2101 displays excellent formability, making it possible to shape it easily into various forms and sizes without altering its mechanical properties - this adaptability suited it ideally for applications including structural components, pressure vessels and piping systems.

Durability: Lean Duplex 2101 exhibits excellent resistance against abrasion, erosion and fatigue for use in demanding applications subject to wear-and-tear damage. This ensures long-term performance in harsh environments.
