What is the recommended installation procedure for ASTM A193 B6 bolts?

This specification covers high-strength stainless steel fasteners for pharmaceuticals, food and beverages, fertilizer production, etc. ASTM A193 B6 boltsuse Grade 410 stainless steel and undergo heat treatment for enhanced tensile strength (~760Mpa).
We recommend buyers to follow these installation steps:

  • Inspect the bolt threads for signs of damage.
  • Adequately tighten per the stated torque figures.
  • Ensure the bolts don’t face undue stress and become prone to failure.

What is the difference between headed and non-headed ASTM A193 grade B6 bolts?

Our company has a rich collection of headed fasteners like A193 Gr B6 square bolts and non-headed ones or studs. The former is created by heating a rod and forging one end into the desired head shape, like a hexagonal. In contrast, non-headed fasteners are better for high-performance applications where security and rigidity are paramount.

As a rule of thumb, headed bolts are appropriate for everyday applications that involve considerable assembly and disassembly. They are more reusable and less expensive than studs.
Clients can also use ASME SA 193 B6 anchor boltswith different head shapes for construction support.

Do any specific factors contribute to the price difference of an A193 B6 stud between India and China?

A193 B6 stud prices in India range from Rs 250 to 380 per kilogram. Chinese companies can offer lower rates of around $0.001 to 3 apiece. On average, per piece costs can be as low as Rs 16 apiece compared to Rs 30-40 in India.
The rapid steel production rate and lower costs in China are the prime factors behind this price difference. Other reasons include:

  • Lower labour costs
  • Prioritising dumping and market flooding as economic practices
  • Less effort is required for health, safety and environmental compliance

However, customers should closely assess the quality and performance of an ASTM A193 Grade B6 hex cap screwbefore purchase.

SA 193 B6 threaded rod and socket head cap screws are available in various sizes, ranging from ¼ inch to 4 inches diameter or custom

Which thread pitches are commonly available for an SA 193 B6 threaded rod?

The thread pitch is a crucial metric for these fasteners, determining the distance between two crests. A lower number indicates a higher thread count. Buyers can purchase an SA 193 B6 threaded rodin diameters up to M100 or M160. Here, the lengths can vary from ¼ inch to 4 inches.

The typical thread pitch conventions are UNC (unified national course) and UNF (unified fine). 8 TPI, or threads per inch, is also available for components over 1 inch.
These rods help extend support and provide greater firmness in critical engineering, marine, and construction applications. Their temperature tolerance is also impressive at up to 800°F.

Are ASTM A193 GR B6 stud bolts suitable for corrosive environments?

ASTM A193 Grade B6 bolts are excellent for corrosive settings in pharmaceuticals, marine sectors, food production, and chemical processing. Their composition is up to 13% chromium with elements like manganese, silicon, and phosphorus. It allows ASTM A193 Gr B6 stud boltsto resist chlorides, mild acids, water, and hydrogen sulfides in oil and gas refineries.

Hilton Steel can supply these components in diameters of ¾ to 1.5 inches or customised dimensions to match client requirements. We conduct suitable testing like IGC (intergranular corrosion) and PMI (Positive Material Identification) to certify the properties of our fasteners and guarantee their fitment to your application.
