What is a B16 stud?
ASTM A193 Grade B16 stud bolts are high strength fasteners manufactured from heat treated Chromium-Molybdenum-Vanadium steel, quenched and tempered. Added Vanadium allows for operating temperatures higher than that of B7 stud bolts. Dimensional specifications are governed by ASME B18. 31.2.
What is the difference between B7 and B16 bolts?
The “big brother” of B7 studs, B16 studs are found in similar situations, but are specified when a higher temperature is required. Vanadium is the main composition difference that separates B16 from B7, allowing the higher temperature limits.
What metal is B16?
B16 alloy steel bar is a chromium, molybdenum, vanadium alloy steel widely used for high strength industrial applications. It is commonly used in power generation turbines in high strength fastener applications such as bolt material.
Is B16 stainless steel?
ASTM A193 Grade B16 bolts and threaded studs are manufactured from a chromium-molybdenum-vanadium alloy steel. Unlike the stainless steel grades within the A193 specification, Grade B16 has no corrosion-resistant properties unless they are coated.
What material is A193 B16?
Chromium-Molybdenum-Vanadium steel
SPECIFICATIONS: ASTM A193 Grade B16 Alloy ASTM A193 Grade B16 is a bolting specification for high temperature service. It is a heat treated Chromium-Molybdenum-Vanadium steel. The specification calls for minimum strength and maximum hardness levels.
Is SA 193 B7 stainless steel?
ASME SA193 B8M Class 1 Stainless steel, AISI 316, carbide solution treated.
What is a B16 stud made of?
chromium-molybdenum-vanadium alloy steel
Grade B16 Studs They are manufactured from a chromium-molybdenum-vanadium alloy steel, Although A193 Grade B16 bolts and studs have similar strength requirements as Grade B7, the fasteners retain strength under high temperatures, and also experience less relaxation at those high temperatures.
What is B16 made of?
Alloy ASTM A193 Grade B16 is a bolting specification for high temperature service. It is a heat treated Chromium-Molybdenum-Vanadium steel. The specification calls for minimum strength and maximum hardness levels. It is considered to be most suitable for bolts used at temperatures below 840°F or 450° C.
What are B7 studs made of?
ASTM A193 Grade B7 bolts are made of chromium-molybdenum steel. The bolts are quenched and tempered (a.k.a heat treated) to develop the desired tensile strength (mechanical properties).
What is the yield strength of B16 studs?
