Monel 400 Tubo senza saldatura in leghe a base di nichel

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 , Tubo , seamless Pipe , Saldati / ERW Pipe , Sheet , Plate , Bobina , Flanges , fasteners , Socket weld Fittings , ferrule fittings , Buttweld fittings Like cap , elbow , tee.

Indicazioni

1.Introduction

Monel 400 è una sorta di lega resistente alla corrosione con il più grande dosaggio, l'uso più estensivo e la Miglior prestazioni complete. Questa lega ha un'eccellente resistenza alla corrosione in acido fluoridrico e fluoro mezzo gassoso e buona resistenza alla corrosione al liquore alcalino concentrato caldo. E' inoltre resistente a corrosione di soluzioni neutre, Acqua, acqua di mare, l'atmosfera e i composti organici. Uno degli aspetti più importanti Caratteristiche della lega è che generalmente non produce crepe da tensocorrosione e ha una buona Prestazioni di taglio.

3.Mechanical property

strength of extension:σb≥450Mpa

Snervamento:σb≥170Mpa

duttilità:δ≥30%

4.resistenza alla corrosione

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, and so on. The corrosion rate is less than 0.025mm/a.

High temperature corrosion: Monel400 continuous work in air generally at about 600 °C, 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.
