Hastelloy C276 Hex Bolts

Hastelloy C276 Hex Bolts - Premium Corrosion-Resistant Fasteners

Unmatched dependability is provided by Hastelloy C276 Hex Bolts when you require fastening solutions that function flawlessly in harsh environments. These high-end superalloy bolts are designed for demanding industrial, power generation, and aerospace applications where conventional fasteners are unable to tolerate the stress and heat. Our product offers the durability required for mission-critical operations because of its remarkable high-temperature strength and resistance to corrosion. At TSM Technology, we produce these speciality bolts in accordance with the strictest industry guidelines, guaranteeing that your projects will be successful even in the most trying circumstances.

What Are Hastelloy C276 Hex Bolts?

The outcome is high-performance fasteners made of a superalloy comprising nickel, molybdenum, and chromium. They are remarkably resistant to reducing and oxidising environments. Up to 1900°F (1038°C), these bolts retain their strength and integrity.

Specification

Chemical And Physical Characteristics

Product Standards

Our hex bolts meet several international standards, including:

• ASTM B166 - Standard specifications for alloys of nickel, chromium, iron, and molybdenum
• UNS N10276 - Designation for a unified numbering system
• ISO 4762 - Screws for socket head caps
• DIN 912 - Screws for socket head caps
• JIS B1176 - Hexagon socket head cap screws​​​​​​​

Application

Corrosive chemicals are treated in reactors, distillation columns, and pipeline systems as part of chemical processing. The marine sector includes desalination facilities, offshore platforms, and seawater uses. Components of steam generators, condensers, and heat exchangers are used in power generation.

Production And Processing Technology

TSM Technology employs advanced manufacturing processes for superior bolt quality. Certified raw materials from approved sources are the first step in our production process. The bolt blanks are made via precision forging, and then CNC machining is used to ensure precise dimensions.

Heat treatment procedures maximise corrosion resistance by optimising the microstructure. Specialised tools made for superalloy materials are used in our threading processes. To guarantee consistency, quality checks are incorporated at every level of manufacturing.

What Steps Go Into Making Product?

Step 1: Raw material inspection and chemical composition verification

Step 2: Hot forging to create bolt blanks with proper grain structure

Step 3: Solution annealing at 1177°C followed by rapid cooling

Step 4: CNC machining to achieve precise dimensions and tolerances

Step 5: Thread rolling or cutting using specialized tooling

Step 6: Surface treatment and passivation

Step 7: Final inspection including dimensional and property testing

Step 8: Packaging with protective materials to prevent contamination

Quality Inspection

Our thorough testing procedure guarantees that each bolt satisfies requirements:

• Chemical analysis using optical emission spectroscopy
• Tensile testing to verify mechanical properties
• Hardness testing using Rockwell C scale
• Dimensional inspection with coordinate measuring machines
• Corrosion testing in simulated service environments
• Ultrasonic testing for internal defect detection

FAQ

Q: Is it possible to use these bolts in heat exchangers?

A: Because of their exceptional resistance to corrosion and high temperatures in harsh thermal settings, they are perfect for heat exchanger applications.

Q: How resistant to corrosion are acidic environments?

A: Over a broad concentration range, these bolts offer outstanding resistance to the majority of acids, including phosphoric, hydrochloric, and sulfuric acids.

Q: Is it possible to order sizes outside of the regular range?

A: Definitely. To satisfy your particular application needs, we produce custom sizes, lengths, and specifications while maintaining the same level of quality.

Q: Which certifications are included in every shipment?

A: For complete traceability, each shipment contains Material Test Certificates (MTC), chemical analysis reports, and mechanical property test results.

Q: What is the difference between these and hex bolts made of stainless steel?

A: The product offers noticeably better corrosion resistance, particularly in settings with chloride, where stainless steel may not hold up.
