Stainless steel stud bolt Carbon steel stud bolt

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 and equipment connections in demanding environments.
