Quantity
Qishine, a trusted China supplier of industrial fasteners, offers the A193 B8 Fastener in a 1/2-inch size, manufactured from ASTM A193 B8 CL.2 stainless steel and paired with A194 GR.8 heavy hex nuts. The set includes one 65 mm bolt and two nuts, conforming to ASME B18.31.2/B18.2.2. A blue XYLAN 1070 coating delivers robust corrosion and wear resistance, extending service life in demanding environments. This combination of material strength and advanced surface treatment makes it a practical choice for moderate-pressure and temperature-sensitive applications across multiple sectors.
Oil & Gas Applications
In upstream and midstream operations, this A193 B8 Fastener is commonly used for flange connections (ASME B16.5), low-pressure vessel bolting (ASME VIII Div.1), and wellhead assemblies. It reliably handles crude oil, natural gas, and steam within a temperature span of –200°C to 540°C (intermittent peaks to 870°C) and pressures up to 1,500 psi. However, it is not recommended for chloride-rich environments (>200 ppm Cl⁻) or high-pressure wellheads, where B8M or B8T grades would be more suitable.

Chemical & Petrochemical Uses
For reactors, pipeline flanges, and storage tanks handling weak acids (e.g., acetic acid), weak alkalis (e.g., ammonia), and organic solvents, the A193 B8 Fastener provides dependable sealing and structural integrity. It performs stably from –50°C to 400°C under pressures up to 1,000 psi. Avoid use with concentrated sulfuric or hydrochloric acid, and assess sensitization risks when operating continuously above 400°C.

Power & Energy Sector
This fastener is also applied in low-pressure boiler systems, heat exchangers, and wind turbine towers, where it endures steam, cooling water, and air at temperatures from –50°C to 400°C and pressures up to 1,000 psi. In high-vibration settings like turbine towers, supplementary locking devices (self-locking nuts or spring washers) are advised. Long-term exposure above 500°C requires evaluation of oxidation and spalling.
