Nickel and nickel-based alloy plates are widely used in chemical processing, marine engineering, and high-temperature environments. Understanding their grades and applicable standards is essential for proper material selection. This guide covers pure nickel plates, key nickel-based alloys, and common specifications.

Material Grades and Applicable Standards

The table below summarizes the most common nickel and nickel alloy plate grades, their key properties, and corresponding standards.

Specifications, Forms and Supply Conditions

Thickness range: 0.05 mm (ultra-thin strip) to 50 mm (medium-thick plate)

Width & length: Width 200–1500 mm, length 500–3000 mm – can be cut to length, strip, or circle

Surface finishes: Hot-rolled black skin (low cost), cold-rolled & pickled, bright annealed, frosted, or mirror finish

Temper conditions:

• Soft state (M) – fully annealed, good plasticity, easy to weld and bend

• Semi-hard (Y2) – cold-work strengthened

• Hard state (Y) – high strength

Packaging: Moisture-proof paper + steel strap bundling; vacuum sealed for sensitive products; outer wooden box or pallet

Quick Application Guide

• For caustic service and reducing media at moderate temperatures → Nickel 200

• For higher-temperature caustic environments requiring intergranular corrosion resistance → Nickel 201

• For seawater or hydrofluoric acid applications → Monel 400

• For high-temperature oxidation and acid corrosion → Inconel 625

• For extremely aggressive environments with strong oxidizers and chlorides → Hastelloy C-276
