Duplex Steel 2507 Plate Supplier Manufacturer

The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion.

Nath Metal INDmetal is a supplier and manufacturer of duplex 2507 plate from india to other parts of globe. Applications below 600 ° F (316 ° C) should only be used with Duplex plate 2507. Extended high temperature exposure can reduce both the resistance to toughness and corrosion of alloy 2507. Duplex 2507 plate has excellent mechanical characteristics. A light gauge of 2507 material can often be used to achieve the same thicker nickel alloy design strength.Duplex 2507 plate is for applications that require outstanding strength and resistance to corrosion. It contains   25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content leads to excellent chloride pitting and shrinkage resistance and 2507 is exceptionally resistant to chloride and stress cracking. The advanced production machinery and raw materials are used for manufacturing plates. We offer resistant to corrosion, cracking, highly welding products.  In order to ensure product quality, we conduct different mechanical, physical and chemical tests. The product is sent together with PMI reports, laboratory test reports,  analysis reports on raw materials, etc. These documents demonstrate the quality of our products. We monitor the delivery of the product. Within the short time, our team attempts to deliver products. Furthermore, we send the Super Duplex S32750/S32760 plates only when they have been properly wrapped or coated and thus the shipment will be safe.

Corrosion Resistance

Inorganic acids are highly resistant, especially if chlorides are present. The plate Alloy 2507 is extremely resistant to intergranular corrosion related to carbide. Due to the ferritic portion of the duplex structure of the alloy, it is very durable in warm chloride environments to resist stress corrosion crackings. Localized corrosion such as pitting and shrinkage is improved by adding chromium, molybdenum, and nitrogen. Local pitting resistance Alloy 2507 is excellent.
