Product Description

Super Duplex Steel Seamless Pipe ASTM A790 UNS S32750 Acid Resistant

ASTM A790 S32750 Seamless Pipe is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel.

(UNS S32750) Duplex stainless steel has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient. Higher chromium, molybdenum and nitrogen content make it has a high ability to resist pitting corrosion, crevice corrosion and general corrosion.

Its impact strength is also very high. 2507 alloy is not suitable for use in a temperature environment higher than 570 ° C. Its toughness will decrease if it is in such an environment for a long time.

Chemical Composition of S32750

Workmanship, Finish, and Appearance

The finished pipes shall be reasonably straight and shall have a workmanlike finish. Imperfections may be removed by grinding, provided the wall thicknesses are not decreased to less than that permitted, in the Permissible Variations in Wall Thickness Section of Specification A999/
A999M.

Ordering Information

1 Quantity (feet, [metres], or number of lengths),
2 Name of material (ferritic/austenitic steel pipe),
3 Process (seamless or welded),
4 Grade (see Table 1),
5 Size (NPS designator or outside diameter and schedule number of average wall thickness),
6 Length (specific or random)

Duplex Stainless Steel Features

Duplex stainless steels have Austenitic and Ferritic stainless steel microstructure, and possess properties in two groups stainless steel, however, there are different.

Versus Austenitic

Higher yield strength
Greater corrosion resistance
Stress corrosion cracking resistance
Not common, used temperate under 250 C.
Fabricability not good as Austenitic
Strictly control heat treatment and welding process
Price stability

Versus Ferritic

Good toughness than Ferric, not hard
Greater corrosion
Fabricability is better
Better weldability
Wide usage than Ferritic
Higher price
