Stainless steel stud bolts are made from austenitic or martensitic stainless steel and are designed for corrosive environments and varying temperature conditions. Their typical chemical composition includes 16 to 18 percent chromium, 8 to 14 percent nickel, and varying amounts of carbon and molybdenum. The tensile strength of these stud bolts usually ranges from 70 to 125 ksi approximately 480 to 860 MPa. Heat treatment involves annealing to maintain flexibility and, in some cases, tempering to increase hardness. The surface hardness of stainless steel stud bolts ranges between 200 and 300 Brinell, and common diameters are produced from 1/4 inch to 3 inches. Threads are manufactured according to ASME B1.1 standard with class 2A or 3A fits.
Operating temperatures for stainless steel stud bolts range from minus 200 to plus 600 degrees Celsius, offering stable performance and excellent corrosion resistance. Their main applications include oil, gas, petrochemical, food, and pharmaceutical industries. Surface coatings are generally unnecessary due to the inherent stainless properties of the steel. Quality control involves tensile testing, hardness testing, chemical analysis, and non-destructive tests such as PT and UT. These stud bolts are ideal for critical connections in industri

Steel stud bolts are manufactured from carbon or alloy steel with precise chemical compositions including carbon, manganese, phosphorus, and sulfur, making them widely used in industrial connections. Depending on the grade, their tensile strength ranges from 60 to 150 ksi. Common grades like ASTM A193 B7 specify a minimum tensile strength of 125 ksi and a yield strength of 105 ksi. Threads are produced according to ASME B1.1 standard with 2A or 3A class fits and have very tight dimensional tolerances. Standard diameters range from 1/4 inch to 4 inches, and lengths can extend to several meters. Surface treatments such as black oxide or hot-dip galvanizing enhance corrosion resistance and durability.
Heat treatment for steel stud bolts includes quenching at 850 to 900 degrees Celsius followed by tempering around 600 degrees Celsius. This process improves hardness, fatigue resistance, and structural stability. Final hardness varies by grade, typically ranging from 200 to 350 Brinell or 24 to 35 Rockwell C. These stud bolts perform well in temperature ranges between minus 29 and plus 427 degrees Celsius. Quality control includes tensile testing, hardness measurement, chemical analysis, and, when required, non-destructive testing such as UT and MPI. Steel stud bolts play a critical

Stainless steel stud bolts are made from corrosion-resistant alloys such as 304 or 316, typically containing 18% chromium and 8–10% nickel. This composition ensures high resistance against corrosion, rust, and chemical exposure. Their tensile strength typically ranges from 75 to 100 ksi, and they can withstand temperatures up to 870°C. These stud bolts are manufactured in compliance with international standards such as ASTM A193 B8 or B8M. Threads are available in both metric and inch sizes, and the surface undergoes precise machining. Stainless steel stud bolts are ideal for use in corrosive environments such as petrochemical plants, food processing industries, and marine applications.
Carbon steel stud bolts are produced from alloy or high-strength carbon steel, usually hardened and tempered through heat treatment. They typically provide a minimum tensile strength of 125,000 psi and a yield strength of 105,000 psi. Main alloying elements include carbon, manganese, chromium, and molybdenum. These bolts are manufactured according to ASTM A193 B7 or DIN 975 standards. The surface is often coated with zinc galvanized or Dacromet to prevent corrosion. This type of stud bolt is widely used in oil, gas, steam, and high-pressure industrial applications, especially for flange an
