Industrial clients can explore this specification to acquire fasteners suitable for steep temperatures and pressures. ASTM A193 B6X bolts use Grade 410 stainless steel, comprising 13% chromium. These products are durable, corrosion-resistant, and strong under challenging conditions.
- Shows a high tensile rating of 620 MPa
- Resists pitting and crevice corrosion
- Can handle exposure to acids like acetic, nitric, and sulfuric (in mild or dilute forms)
- Rigid, with a hardness of 262 HRB
A193 Grade B6X stainless steel anchor bolts frequently work in chemical processing, oil refineries, and food and beverage industries.
SA 193 grade B6X studs manufacturer in India
The standard finishes of an SA 193 Grade B6X hex bolt are plain, pickled, and passivated. The passivation procedure employs nitric or citric acid to clean the surface of impurities, contaminants, and free iron. It boosts the overall corrosion resistance and service life.
We also deliver zinc plated or galvanised (hot dip) fasteners for clients who need more resilience to handle corrosive agents.

SA 193 Grade B6X hex bolt
ASME SA 193 B6X stud bolts
From atmospheric stress to warm chloride environments, the corrosion resistance capabilities of ASME SA 193 B6X stud bolts are impressive. We can assist our clients with improving these properties through hardening and tempering treatments.
Polishing and special surface coatings like galvanisation (zinc) and PTFE can also boost the corrosion resistance of ASTM A193 Grade B6X stainless steel square bolts.
As stockist of B6x material at factory price, we stock and supply ASTM A193 grade B6x bolts which are quenched and tempered at a minimum temperature of 593°C

The magnetic properties of stainless steel depend on the composition, i.e., the iron content and the microstructure. ASTM A193 B6X stainless steel studs are magnetic due to their martensitic (and not austenitic) structure. Besides iron and chromium, these products contain manganese, phosphorus, sulfur, carbon, and silicon.
The typical production methods for these fasteners are forging (cold or hot forged) or stock machining, followed by the required heat treatments. However, the magnetic properties are valid in both annealed and hardened states.

Threaded rods provide heightened rigidity, stabilisation, and support in construction and engineering. An A193 B6X stainless steel threaded rod delivers a secure seal in high-stakes shipbuilding and power generation applications.
Unlike bolts with threading on one end, these rods get threaded on both.
We recommend considering the following to choose the fastener for your application:
- Load size
- Balance and stability: For example, an A193 B6X hex cap screw will be better for high-precision applications.
- Environmental conditions like temperature and pressure
- Presence of corrosive agents
- Budget and availability in required sizes: These fasteners usually get produced between 1/4 to 4 inches.
- Design and finish: You can explore fully or partially threaded rods with finishes like zinc plating.
We guarantee fastest delivery of A193 B6X stainless steel anchor bolts and socket head cap screws used in high temperature and high pressure services
Strength testing is essential for ASME SA 193 GR B6X heavy hex bolts operating in sensitive settings like pressure vessels and petrochemical plants. The standard procedures determine the maximum allowable strain before failure. Hilton Steel can guarantee the following performance and quality tests:
- Routine tensile testing
- Proof load test
- Wedge test (to check the stress a fastener can endure)
- PMI or Positive Material Identification
- Tests for corrosion resistance
We summarise the test results in the corresponding MTC. Customers can also request special assessments or commission a third-party examination.
