Ni 200 Plates (UNS N02200/W. Nr. 2.4060) : Commercially Pure Nickel for Corrosive and High-Temperature Service

Product Overview

Ni 200 Plates (UNS N02200/W. Nr. 2.4060) are wrought, commercially pure nickel (≥ 99.0 %) sheets designed to maintain purity and performance in the most aggressive environments. Their near-monolithic nickel content delivers superior resistance to reducing acids and caustic alkalies—critical for chemical-process vessels, piping, and pumps—while avoiding stress-corrosion cracking in chloride solutions. With excellent weldability and ductility (elongation up to 40 %), they can be formed into complex geometries without compromising toughness. Ni 200 Plates exhibit high thermal conductivity (70.3 W/m·K at 20 °C) and electrical conductivity, making them ideal for heat-exchanger panels, electrical contacts, and semiconductor-processing equipment. Their high melting range (1435 – 1446 °C) and stable mechanical properties across − 196 °C to 400 °C ensure reliability in cryogenic to elevated-temperature applications. Conformance to ASTM B162/ASME SB162, AMS 5553, and ISO 15156-3/NACE MR0175-3 assures global interchangeability and compatibility with sour-gas environments.

Frequently Asked Questions

Q1: How does Ni 200 Plate resist corrosion?
A1: Its virtually pure nickel matrix (≥ 99 %) forms a stable protective film in reducing acids and caustic solutions, avoiding pitting and stress-corrosion cracking in chloride environments.

Q2: What temperature range can Ni 200 Plate handle?
A2: Maintains mechanical integrity from − 196 °C to 400 °C and resists melting up to 1435 – 1446 °C, with stable tensile properties in this range.

Q3: Is Ni 200 Plate weldable and formable?
A3: Yes—excellent weldability (TIG/GTAW, EB) and ductility (up to 40 % elongation) permit complex forming and joining without embrittlement.
