Hastelloy Fasteners in Mumbai

Nishra Overseas supplies Hastelloy Fasteners in Mumbai for industrial applications where fastening components need to withstand demanding corrosive and high-temperature environments. Hastelloy is a family of nickel-based alloys used in applications involving aggressive chemical media, reducing and oxidizing conditions, chlorides, and other severe service environments.

The suitable Hastelloy grade and fastener specification depend on the operating temperature, chemical composition, concentration, pressure, mechanical requirements, and applicable project standards. Nishra Overseas works with industrial buyers, EPC contractors, OEMs, fabricators, and procurement teams to supply Hastelloy fasteners according to the required material and dimensional specifications.

The company is based in Mumbai and supplies industrial metal products to customers in India and international markets. Its official website states that Nishra Overseas was established in 1998 and exports to more than 50 countries.

Hastelloy Fasteners Manufacturer in Mumbai

Nishra Overseas states that it maintains extensive inventory across its product portfolio, but availability of a particular Hastelloy fastener should be confirmed before placing an order.

Hastelloy Fastener Grades

Hastelloy fasteners are not manufactured from one universal alloy. Grade selection should be based on the service environment and technical requirements.

Hastelloy C276

Hastelloy C276, UNS N10276, is a low-carbon nickel-chromium-molybdenum alloy used for demanding corrosion-resistant applications. ASTM B574 specifically covers rod and bar products made from alloys including UNS N10276 and UNS N06022 for general corrosive service.

Hastelloy C22

Hastelloy C22, UNS N06022, is a nickel-chromium-molybdenum alloy used in applications requiring resistance to aggressive and mixed corrosive environments. The alloy is also included within the scope of ASTM B574 for applicable rod and bar products.

Hastelloy B2

Hastelloy B2, UNS N10665, is a nickel-molybdenum alloy associated with demanding reducing environments. The appropriate product specification should be confirmed according to the required fastener form and application.

Hastelloy B3

Hastelloy B3, UNS N10675, is another nickel-molybdenum alloy used for demanding corrosion-resistant applications. As with other Hastelloy grades, the exact material and product specification should be confirmed against the customer's engineering requirement.

Hastelloy Fastener Specifications and Standards

The applicable standard depends on what is being specified: the alloy/product form, the finished fastener, the dimensions, or the customer's project requirement.

ASTM B574 covers specified nickel-based alloy rod and bar products, including alloys such as UNS N10276 and UNS N06022. It should therefore not automatically be presented as a finished-fastener standard.

ASTM B564 covers nickel-alloy forgings and includes various nickel alloy compositions. It can therefore be relevant when the fastener or component is supplied in a forged product form and the applicable alloy is within the specification's scope.

For certain commercial wrought nonferrous fasteners, ASTM F468 covers bolts, hex cap screws, socket head cap screws and studs, while ASTM F467 covers applicable nonferrous nuts. These standards have their own dimensional, chemical and mechanical requirements and should only be specified where the particular fastener, alloy and application fall within their scope.

Other dimensional or thread requirements may be specified through applicable ASME, ANSI, DIN, ISO, or customer-specific standards.

Therefore, a purchase specification should identify the Hastelloy grade, UNS designation, fastener type, dimensions, thread requirements and applicable product/fastener standard rather than relying on a generic ASTM reference.

Hastelloy Fastener Product Range

Depending on the customer's requirement, Hastelloy fastening products may include:

Hex Bolts

Hastelloy hex bolts are used for bolted connections in industrial equipment, fabricated assemblies, piping-related components, and machinery where corrosion resistance is important.

Stud Bolts

Hastelloy stud bolts can be used in flanged and equipment connections where the specified nickel alloy is required for the service environment.

Hex Nuts

Hastelloy nuts can be supplied for use with compatible nickel-alloy bolts and studs. Material compatibility between the mating fastener components should be considered during specification.

Washers

Washers may be specified where load distribution and compatibility with the fastening assembly are required. The appropriate alloy and dimensional requirement should be confirmed for the application.

Custom Fasteners

Custom Hastelloy fasteners can be considered for applications requiring non-standard dimensions, special thread configurations, specific drawings, or project-specific material requirements.

Manufacturing and Quality Requirements

Hastelloy fastener quality depends on both the alloy and the manufacturing route used to produce the finished component.

Depending on the order specification, fasteners may be produced through cold forming, hot forming, machining, forging, or other appropriate manufacturing processes. The applicable manufacturing method should be selected according to the alloy, geometry, size, mechanical requirements, and customer's specification.

Nishra Overseas states that its quality system is ISO 9001:2015 certified and that it maintains material traceability through original Mill Test Certificates, PMI testing, heat and lot marking, and documented quality records.

Inspection requirements can be defined before order confirmation. Depending on the product and specification, these may include:

Chemical composition verification
PMI testing
Mechanical testing
Hardness testing
Dimensional inspection
Visual inspection
Ultrasonic testing where applicable
Other non-destructive testing where specified
Third-party inspection

Nishra Overseas states that third-party inspection is accepted and lists inspection/testing capabilities including chemical analysis, mechanical testing, dimensional inspection and several NDT methods.

Applications of Hastelloy Fasteners

Hastelloy fasteners may be considered for industrial applications where conventional fastening materials do not provide the required corrosion resistance or service performance.

Typical application areas include:

Chemical Processing Equipment
Petrochemical Plants
Oil and Gas Equipment
Pharmaceutical Processing
Power Generation
Pollution Control Equipment
Marine Equipment
Process Piping
Pressure Equipment
Heat Exchanger Assemblies
Industrial Reactors
Pumps and Valves
Fertilizer Plants
Heavy Engineering Equipment
Industrial Fabrication

The final material selection should be based on the actual process environment rather than the application name alone.
