Typical Applications
UNS S42200 / AMS 5655 has been used typically for parts requiring corrosion resistance, stress-corrosion resistance, high strength up to 1200F ( 650℃ ), and good ductility and strength in the transverse direction in large section sizes, but usage is not limited to such applications.
Referenced Relevant Standards
ASTM A370 Mechanical Testing of Steel Products.
ASTM A604 Macroetch Testing of Consumable Electrode Remelted Steels.
ASTM E112 Determining Average Grain Size.
ASTM E353 Chemical analysis of stainless, heat-Resisting, maraging and Other Similar Chromium-Nickel-lron Steels.
Meltng Process Route
This alloy is generally smelt in Basic Electric Furnace (EAF, AOD) + Electroslag remelting (ESR). For a purpose of superior quality, it should be smelt via technology of vacuum refining or by agreement.
