Solitaire Fittings is a trusted Alloy Steel Fasteners Manufacturer and Supplier in India, offering a complete range of high-strength, corrosion-resistant alloy steel bolts, nuts, washers, and threaded fasteners for diverse industrial applications. Our fasteners are designed for durability, toughness, and superior mechanical performance, making them ideal for use in demanding environments such as oil & gas, petrochemical, power generation, and marine industries.
What Are Alloy Steel Fasteners?
Alloy Steel Fasteners are hardware devices made from alloy steel, a type of steel enhanced with additional elements such as chromium, nickel, molybdenum, and vanadium to improve strength, hardness, and resistance to wear and corrosion.
These fasteners play a vital role in connecting mechanical parts and structures securely. Compared to regular carbon steel fasteners, alloy steel fasteners deliver superior tensile strength, improved heat resistance, and enhanced fatigue performance.
Whether you need alloy steel bolts, alloy steel nuts, alloy steel washers, or alloy steel stud bolts, Solitaire Fittings manufactures fasteners that meet international standards like ASTM, ASME, DIN, ISO, and BS
Key Features of Alloy Steel Fasteners
- High Tensile Strength – Can withstand heavy loads and mechanical stress.
- Excellent Corrosion Resistance – Resists oxidation and rust in harsh environments.
- Superior Heat Resistance – Performs well under high temperatures.
- Enhanced Durability– Provides long service life with minimal maintenance.
- Dimensional Accuracy– Precisely engineered for tight-fitting assemblies.
- Ease of Fabrication– Suitable for machining, threading, and heat treatment.
