Unifit Metalloys Inc. is an eminent manufacturer of Stainless Steel ASTM A194 Grade 8 Hex Nuts, which are typically used for elevated temperature applications. ASTM A194 Grade 8 Stainless Steel Hex Nuts is an austenitic heat resistant alloy with phenomenal resistance to oxidation under mildly cyclic conditions. ASTM A194 Stainless Steel Grade 8 Hex Nuts offers high strength for roll formed structural components, and also low work hardening rate grade for cold heading fasteners. ASTM A194 Grade 8 Alloy Hex Nuts has many of the same characteristics and applications, such as the ability to withstand high temperatures, resistance to oxidation and corrosion, and machinability.

Because of its high chromium and medium nickel contents, Stainless Steel ASME SA 194 Grade 8 Hex Nuts has good resistance to sulfidation and other forms of hot corrosion. ASME SA 194 Grade 8 Stainless Steel Hex Nuts is an austenitic heat-resisting stainless steel. It is noted for excellent resistance to scaling in continuous service up to 1150 Degree C, and in intermittent heating/cooling conditions up to 1095 Degree C.

Table of Content

The strength of ASME SA 194 Stainless Steel Grade 8 Hex Nuts is a combination of good strength and corrosion resistance in temperatures up to 2100 Degree F. ASME SA 194 Grade 8 Alloy Hex Nuts is a high temperature chromium nickel austenitic stainless steel with high creep strength that resists oxidation at temperatures in dry air.
