ASTM B16 Stud Bolts: High-Strength Fasteners for Elevated Temperatures
ASTM B16 stud bolts are made from a special grade of chromium-molybdenum-vanadium alloy steel, designed to provide exceptional strength and performance in high-temperature applications. These fasteners are commonly used in industries requiring reliable connections under extreme pressure and heat, such as power plants, chemical processing, and refineries.
ASTM B16 Stud Bolt Composition
ASTM B16 specifies a chromium-molybdenum-vanadium alloy steel, designed for high-strength applications under elevated temperatures. Below is the typical chemical composition of ASTM B16 material:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.20 – 0.35 |
| Manganese (Mn) | 0.50 – 1.00 |
| Phosphorus (P) | Max 0.035 |
| Sulfur (S) | Max 0.040 |
| Silicon (Si) | 0.15 – 0.50 |
| Chromium (Cr) | 0.80 – 1.50 |
| Molybdenum (Mo) | 0.45 – 0.65 |
| Vanadium (V) | 0.25 – 0.35 |
ASTM A193 Grade B16 is a standard specification for alloy steel bolts, studs, and other high-temperature fasteners commonly used in pressure vessels, valves, flanges, and fittings for high-temperature service.
