Product Description

ASTM B668 / ASME SB668 UNS N08028 Alloy 28 Seamless Pipe & Tube

N08028 stainless steel is a superaustenitic (highly alloyed) stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. N08028 is the UNS number for this material. Alloy 28 is the common industry name.

It has a moderately high base cost among wrought superaustenitic stainless steels. In addition, it has a moderately high ductility and a moderately high embodied energy.

The graph bars on the material properties cards below compare N08028 stainless steel to: wrought superaustenitic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Yuhong Group, now is professional for various kinds of special materials in China.

Alloy 28 seamless pipe as a kind of Nickel Alloy, now is widely used into many fields, such as: Thermal Equipments, PetroChemical, Oil & Gas application
