ASTM A194 Grade 8C Nuts

ASTM A194 Grade 8C Nuts belong to the ASTM A194 specification and 8C grade. There are different dimensions such as ASME B18.2.1 and B18.3 to govern the dimensions of these nuts. The nut sizes range from ¼ inches to 2 ¾ inches and there are different width across flats and width across corner values. The ASTM A194 Grade 8C Hex Nuts also come in different thicknesses such as basic, minimum and maximum thickness values.

The material has carbon, manganese, silicon, phosphorus, sulfur, 17% chromium, 9% nickel and iron in the composition. This allows the A194 Grade 8C Heavy Hex Nuts to have certain mechanical properties. The nuts have 550MPa minimum tensile strength and 240MPa minimum yield strength with 30% elongation rate. The ASME SA 194 Gr 8C Nut also has 223BHN minimum hardness values. The nuts come in different types such as lug nuts, lock nuts, dome nuts, cone nuts, cap nuts, hex nuts, square nuts and flanged nuts as well. Each of these SA 194 Gr 8C Nut types are used differently. These nuts can be used under high temperature, high pressure and high stress conditions. The corrosion resistance of the ASTM A194 Grade 8c Nuts also allows them to be used in general corrosive applications. The applications include specialty chemicals, pharmaceuticals, petrochemicals, aircraft exhaust manifolds, sea water equipment, gas processing, heat exchangers, power generation and off shore oil drilling.
