Profile

This page is mainly introduced the AMS 6305E 17-22A chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of AMS 6305E 17-22A,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.

Steel, Heat-Resistant, Bars, Forgings, and Tubing 0.95Cr - 0.55Mo - 0.30V (0.40 - 0.50C) Vacuum Arc Remelted.

Melting Practice

Steel shall be multiple melted using consumable electrode vacuum practice (VAR) in the remelt cycle.

Macrostructure

Visual examination of transverse full cross-sections from bars, billets, tube rounds (solid, not hollow), and forging stock,

etched in hot hydrochloric acid in accordance with ASTM A 604, shall show no pipe or cracks. Porosity, segregation, inclusions, and other imperfections shall be no worse than the macrographs of ASTM A 604 shown in Table 2.
