Inconel 718 `Stainless Steel Alloys
ASTM B637 Inconel 718 Products, Alloy 718 Material Dealers
To produce Inconel alloy 718, it undergoes a specific heat treatment process: it is heated to 1850-1900°F to dissolve any precipitates, then aged at 1450°F for six to eight hours, followed by air cooling. This treatment helps optimize its properties for use in demanding environments such as oil fields, where it must meet strict standards like NACE MR0175, ensuring it remains strong yet not excessively hard (maximum hardness of 40 Rockwell C).
