In high-performance industries, engineers face constant challenges with wear, galling, and fretting in components that operate under sliding or abrasive conditions. While stainless steels like 304 and 316 provide adequate corrosion resistance, they often fail when friction or metal-to-metal contact is involved. To solve this challenge, Nitronic 60 (UNS S21800) was developed.

Nitronic 60 is an austenitic stainless steel alloy specifically designed to resist galling, fretting, and wear, while also offering strength and corrosion resistance comparable to 316 stainless steel. When manufactured in wire form, Nitronic 60 becomes a highly versatile material for use in springs, welding filler materials, fasteners, screens, wire mesh, medical equipment, and automotive parts.

Nitronic 60 wire combines strength, ductility, corrosion resistance, and wear resistance in one product, making it indispensable in industries like oil & gas, chemical processing, aerospace, marine, medical, and power generation.

The alloy derives its unique wear and corrosion resistance from a carefully balanced chemistry:

• Tensile Strength: 690 – 750 MPa

• Yield Strength: 380 – 420 MPa

• Elongation: 35 – 40%

• Hardness: 160 – 220 HB

• Fatigue Resistance: Excellent under cyclic stress

• Impact Strength: Maintains toughness at cryogenic temperatures

• Density: 7.9 g/cm³

• Melting Range: 1370 – 1425 °C

• Elastic Modulus: ~200 GPa

• Thermal Conductivity: ~14 W/m·K

• Electrical Resistivity: 0.00078 Ω·cm

• Specific Heat: ~500 J/kg·K

Nitronic 60 wire undergoes stringent testing:

• Mechanical Tests: Tensile, yield, elongation, hardness.

• Corrosion Tests: Pitting, crevice, intergranular corrosion.

• Non-Destructive Tests (NDT): Eddy current, ultrasonic, radiographic.

• Surface Inspections: For cracks, inclusions, and uniform finish.

• Dimensional Checks: Diameter tolerance, roundness.

• Production Capacity: IN KGS
• Delivery Time: READY STOCK
• Packaging Details: The packaging of the product is done using an effective method of packaging. It all includes- • Shrink-wrapping • Bubble wrapping • Carton boxes • Wooden crates/pallets/boxes

Nitronic 60, also known as UNS S21800, is a high-performance austenitic stainless steel alloy designed for outstanding resistance to wear, galling, and fretting. Unlike conventional stainless steels such as 304 or 316, Nitronic 60 contains carefully balanced amounts of silicon and manganese that provide exceptional wear resistance while maintaining excellent corrosion resistance.

When manufactured into fittings – such as elbows, tees, reducers, couplings, caps, crosses, stub ends, and unions – Nitronic 60 serves as a reliable solution for fluid handling, piping systems, and high-stress applications in industries ranging from chemical processing and marine engineering to aerospace, oil & gas, and power generation.

The chemical composition of Nitronic 60 plays a critical role in defining its wear resistance and corrosion properties:

• Tensile Strength: 690 – 750 MPa

• Yield Strength (0.2% offset): 380 – 420 MPa

• Elongation: 35 – 40%

• Hardness: 160 – 220 HB

• Modulus of Elasticity: 200 GPa

• Density: 7.9 g/cm³

• Melting Range: 1370 – 1425 °C

• Specific Heat: 500 J/kg·K

• Thermal Conductivity: 14 W/m·K

• Electrical Resistivity: 0.00078 Ω·cm

Nitronic 60 fittings undergo strict testing to meet industrial standards:

• Mechanical Tests: Tensile, yield, hardness, impact tests.

Stainless steels are widely used in industries due to their corrosion resistance, durability, and mechanical strength. However, many grades, including conventional austenitic stainless steels such as 304 and 316, face challenges when exposed to environments involving sliding wear, galling, and fretting corrosion. To address this limitation, Nitronic 60 (UNS S21800) was developed.

Nitronic 60 is an austenitic stainless steel alloy specifically designed to provide excellent resistance to wear and galling, combined with high strength and oxidation resistance. When fabricated into pipes, Nitronic 60 offers an exceptional solution for industries that require piping systems exposed to corrosive fluids, abrasive slurries, and environments where metal-to-metal contact is unavoidable.

Nitronic 60 pipes are widely used in oil & gas, marine, chemical processing, pulp & paper, automotive, aerospace, and power generation industries. They combine strength, toughness, and corrosion resistance, making them one of the most versatile and cost-effective materials for demanding applications.

The properties of Nitronic 60 pipes come from their unique chemical composition:

• Tensile Strength: 690 – 750 MPa

• Yield Strength (0.2% offset): 380 – 420 MPa

• Elongation: 35 – 40%

• Hardness: 160 – 220 HB

• Impact Resistance: High, even at cryogenic temperatures

• Fatigue Resistance: Excellent under cyclic stress

• Density: 7.9 g/cm³

• Melting Range: 1370 – 1425 °C
