Nuts of the ASTM A194 Grade 7 variety are made of chromium-molybdenum alloy steel and are internally threaded and heat-treated. This specification describes the nuts. Shree Ashapura Steel is a major manufacturer and supplier of various grades of the ASME SA 194 Gr 7 Hex Nut and other types of hex nuts.

Because they are well-designed for high torque tightening, hex nuts are extremely frequent in this grade. The A194 specification calls for several distinct grades, including AISI 4140, 4142, 4245, and 4145H, among others. Hot forging, cold forging, and machining are the three processes that are used to manufacture the ASTM A194 Gr 7 Heavy Hex Nuts from bar stock that has been heating treated.

About ASTM A194 Gr.7 Nut

The substance can be broken down into its parts: carbon, manganese, phosphorus, sulfur, silicon, chromium, and molybdenum. The sizes of the fasteners range from one-quarter of an inch to one and one-half inches, and the number of threads per inch can be anywhere from eight to twenty.

Tensile strengths of between 150 and 175 ksi can be found in SA 194 Grade 7 Nuts, which come in sizes ranging from M6 to M100. These fasteners find use in various industries, including the oil and natural gas, petrochemical, biochemical, pharma, and power generation sectors. In addition to their use in boilers, coolers, furnaces, heat exchangers, and capacitors, ASTM a194 grade 7l nuts are also applicable in these other types of equipment. We are a market-leading manufacturer of the wide varieties of these fasteners. Therefore we are able to fulfill any order requirements that you may have.
