HR6W

<Features>
(a) Stability of long term creep-strength and superior creep rupture ductility
(b) Much better corrosion resistance than 18Cr-8Ni austenitic stainless steels
(c) Microstructual phase stability at elevated temperature, which contributes
     to superior stress relaxation and enough fatigue properties for various applications

<Equivalent steel grade, chemical compositions>

• ASTM B167 N06674, ASME SB167 Code Case 2684
• 23Cr-45Ni-7W-Ti-Nb
