Bhansali Exports, a trusted supplier and exporter in Mumbai, India, offers high-quality Alloy 20 Fasteners for demanding service conditions. Alloy 20 is a nickel-iron-chromium alloy including molybdenum and copper. It is designed to resist corrosion in acidic and chloride environments. These fasteners comply with ASTM B473, B462, and ASME B18 requirements, as well as DIN specifications. The material is extremely resistant to sulfuric acid, stress corrosion, cracking, and pitting. It provides excellent strength, a long service life, and consistently performs at low and moderate temperatures. This makes it an effective option for demanding industrial applications.
We offer bolts, nuts, stud bolts, and washers in a variety of sizes and finishes. Bolt and screw sizes range from M3 to M56 and 3/6" to 2". Custom sizes are also available. We offer nuts and washers ranging from M3 to M56 and 3/6" to 2". Machine screws range from M1.6 to M12, and self-tapping screws range from No.2 to No.14. Standard lengths range from 3 to 200 mm. Products are manufactured in accordance with DIN 931, 933, 934, 7991, 976, and 125, as well as ASME B18.2.1 and B18.3. Each size is manufactured with precise tolerances to provide a suitable fit and secure assembly.
Table Content
Our production process follows strict process control at every stage. Machining and CNC techniques are used to create custom connecting parts that adhere to accurate specifications. We ensure that each batch passes visual, dimensional and mechanical tests. Chemical analysis confirmed the correct alloy composition. We provide test certificates, such as the EN 10204 / 3.1 Manufacturer Test Certificate, and quality checks verify that fasteners perform effectively in crucial operating circumstances.
Alloy 20 Fasteners are used in oil and gas plants, chemical units and petrochemical systems. The material performs well in units where corrosion control is vital. It is also used in marine service, shipbuilding, and refining units. Power plants and energy projects rely on this alloy for stable joint strength. Paper mills, construction sites, and aerospace units also use these fasteners for secure assembly. High resistance to acid attack and good strength make the product suitable for heavy-duty service.
