Coude 90° LR BW 3 SCH160 A 815 Gr.UNS S31803 CLASS WP-S (duplex)

We marked Duplex Steel Buttweld Fittings with Grade, Heat No, Size, Standard and Thickness. Our workers wrapped ASTM A815 UNS S31803 Elbow with water-proof material, and put them into wooden case or pallets, then bundled packages with nylon rope.

Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. great care is taken during operation and transportation.

Inspection

1. Visual the surface of duplex stainless steel elbow fittings.

Features

Duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels. However, the corrosion resistance of the least resistant duplex stainless steels is much better than most commonly used grades of stainless steels 304 and 316.
