ASTM F594 Nuts
ASME SF594 Washers manufacturer in india at best price, Check F594 Hex Nuts Dimensions
ASTM F594 Nuts are made up of different alloy materials. There are several groups of alloys such as austenitic, ferritic, martensitic and precipitation hardened types. Viha Steel & Forging is a leading manufacturer and supplier of the different types of ASTM F594 Stainless Steel Nuts in diameters ranging from ¼ inches to 1 ½ inches according to the ASTM F594 specification. The materials range as 303 grade, 304, 305 up to 630 grades of stainless steel. The markings on the ASTM F594 Hex Nuts and the other types denote the different conditions of the nuts.
The hex nuts are mostly used because of their strength and application with tools. The proof stress of the hex nuts ranges from 75ksi to 100ksi depending on the material grade. The ASTM F594 Washers are one of the important fasteners often used with bolts and nuts. The washers are useful in places where the bolts and nuts have to tighten over gaps. There are different types of washers as spring washers and flat washers as well. The ASTM F594 Nut Dimensions vary according to the application type, material type and the production methods.
The hardness of the nuts also differs with the material type and the size of them. The mostly used of all these material grades is the 304 F594 Stainless Steel Washers and nuts because of their low cost and strength with general corrosion resistance. The material has carbon, manganese, phosphorus, sulfur, silicon, 18% chromium and 8% nickel in the composition with copper added up to 1% for corrosion resistance. The 316 grade has up to 3% molybdenum for chloride ion stress resistance. As a leading supplier, we supply the ASTM F594 Heavy Hex Nut and other types of nuts in this specification. Please feel free to contact us for more information on the different types of nuts and their pricing.

A Tensile stress areas are computed using the following formula: AB = 0.7854 [D- (0.9743/n)]2
Where:
AB = Tensile stress area, inch2,
D = Nominal size (basic major diameter), in., and,
n = number of threads per inch.
