Product Description

ASTM A815 UNS 31803 Fittings

Duplex Steel Buttweld Fittings

Package

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.
2. Check the marking. Such as size, material code, grade, thickness, heat No.
3. Measure the diameter and thickness whether in tolerance.
4. Test the chemical properties of ASTM A815 UNS S31803 Pipe 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.
