Quantity
The ASME A193 B16 Stud Bolt is manufactured from high-strength chromium-molybdenum alloy steel, compliant with ASME standards, and offers excellent mechanical properties and high-temperature resistance, making it suitable for demanding high-pressure and high-temperature applications. With size ranges from 30 to 1000 mm, its surface is treated with black oxide coating to enhance corrosion resistance. The ASME A193 B16 Stud Bolt is widely used in critical equipment connections in industries such as oil, natural gas, chemicals, and power generation, making it an ideal choice for ensuring safety and reliability.
With its high strength, high-temperature resistance, and corrosion resistance, the ASME A193 B16 Stud Bolt has become the preferred fastener for high-pressure pipeline flanges, reactors, valves, and other equipment, meeting diverse installation requirements.
As a high-strength alloy steel product, the surface treatment and corrosion resistance of the ASME A193 B16 Stud Bolt are critical factors in ensuring its long-term stable performance in demanding conditions. To meet the needs of high-pressure, high-temperature, and corrosive environments, the ASME A193 B16 Stud Bolt is typically treated with black oxide coating. These processes not only significantly enhance its corrosion resistance and wear resistance but also extend the product’s service life.
1. Black Oxide Coating
Black oxide coating is a common surface treatment process that forms a dense black oxide layer (Fe₃O₄) on the fastener’s surface through chemical or thermal treatment. This oxide layer has the following characteristics:
- Thickness: The oxide layer is typically 0.5-1.5 microns thick, uniformly covering the surface of the ASME A193 B16 Stud Bolt.
