ASTM A790/ASME SA 790 UNS S31803 pipe

Duplex S31803 Pipe, Duplex SA 790 S31803 Pipes, Duplex Steel S31803 Pipes Stockist, Duplex Steel UNS S31803 Pipes.

ASTM A790 UNS S31803 pipe is an imperishable alternative with excellent flexibility. These pipes are considered one of the most ductile and strong pipes in the metal industry. We at Calico Metal Alloys provide these pipes at a very nominal price, and we manufacture these products using high superior quality raw material. 

Duplex S31803 pipes are highly used for commercial and industrial purposes, and these pipes are used for transferring harmful chemicals, fluids, and gases from one place to another. ASTM A790/ASME SA 790 UNS S31803 pipes are enriched with great weldability and strength. The grade provides excellent flexibility and durability. 

Chemical composition: 

The chemical composition of ASME SA790 UNS S31803 pipes includes a high amount of chromium, nickel, and molybdenum. These elements are known for providing strength and malleability to the grade. ASTM A790/ASME SA 790 UNS S31803 grade also includes elements like silicon, sulfur, manganese, nitrogen, phosphorus, etc., to provide stability to the grade. 


Pipes are generally used for transferring and diverting the flow. These pipes are available in various types and grades. Duplex Steel UNS S31803 pipes have a remarkable ability to withstand high heat pressure and bad weather conditions. These pipes are highly recommended in most industries because of their extraordinary capabilities. The grade provides excellent resistance from corrosion, crevice corrosion, and stress cracking, and it also protects from rusting, reduction, and erosion.
