Monel 400 Nickel-Base Alloys Seamless Tube

ASTM B 163 / B730 / ASTM B165 / B725 Nickel Alloy Pipe Monel 400 / EN 2.4360 / Monel K500 / 2.4375

Monel 400®, Nickelvac® 400, Nicorros® 400 Monel 400 is a combination of nickel and copper and is hardened by cold working only. This alloy is widely renowned for for its corrosion resistant properties against flowing sea – water and is extensively used for marine applications. Monel is also extremely resistant to stress corrosion cracking in most freshwaters. High temperature ( up to 1000 °F) has no effect on this alloy and it also has excellent mechanical properties at subzero temperatures.
Monel 400 is available in many forms like wire , Round bar, Forged bar , hex bar , Flat bar , Circles , Ring , Tube , seamless Pipe , Welded / ERW Pipe , Sheet , Plate , Coil , Flanges , fasteners , Socket weld Fittings , ferrule fittings , Buttweld fittings Like cap , elbow , tee.

Specifications

1.Introduction

Monel 400 is a kind of corrosion resistant alloy with the largest dosage, the most extensive use and the best comprehensive performance.This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium and good corrosion resistance to hot concentrated alkali liquor.It is also resistant to corrosion of neutral solutions, water, sea water, atmosphere and organic compounds.One of the important characteristics of the alloy is that it generally does not produce stress corrosion cracks and has good cutting performance.

3.Mechanical property

strength of extension:σb≥450Mpa

yield strength:σb≥170Mpa

ductility:δ≥30%

4.corrosion resistance

Acid medium: Monel400 is corrosion resistant in sulfuric acid with a concentration of less than 85%.

Monel400 is one of the few important materials in hydrofluoric acid resistance.

Water corrosion: Monel400 alloy not only has excellent corrosion resistance in most cases of water corrosion, but also is seldom found with hole corrosion, stress corrosion, etc. The corrosion rate is less than 0.025mm/a.

High temperature corrosion: Monel400 continuous work in air generally at about 600 ℃, the highest temperature in the high temperature steam, corrosion rate is less than 0.026 mm/a.Ammonia:because Monel400 high nickel alloy content, reason can be below 585 ℃ anhydrous ammonia and ammoniation under the condition of corrosion.
