Lork High Hardness DIN 2.4375 Monel K500 Nickel Based Alloy Plate for Sea Water Pump Shafts

Introduction

Super alloys contain many elements in different combinations so as to achieve a desired result. They have the ability to function at very high temperatures and under severe mechanical stress, and also where high surface stability is required. They have good creep and oxidation resistance. There are three groups of alloys, namely cobalt-based, nickel-based, and iron-based alloys.

Nickelvac K-500 is an age-hardenable version of Monel 400 alloy. It has high strength and sea water corrosion resistance. The following datasheet gives more details about Nickelvac K-500.

The following table shows the chemical composition of Nickelvac K-500.

Nickelvac K-500 is machined in the annealed condition.

Nickelvac K-500 can be formed using standard methods in the annealed condition.

Nickelvac K-500 is welded using all conventional methods in the annealed condition. After this process, stress-relief annealing is performed for the finished weldment.

Nickelvac K-500 is heat treated by annealing. It can also be precipitation-hardened by performing aging heat treatment.

Nickelvac K-500 is forged at 1038 to 1149°C (1900 to 2100°F) followed by quenching in water.

Nickelvac K-500 is hot worked at 872 to 1149°C (1600 to 2100°F) followed by quenching in water. It should not be cooled below 872°C (1600°F).

Nickelvac K-500 can be cold worked using standard methods

Nickelvac K-500 is annealed at 1038°C (1900°F) followed by quenching in water.

Annealed or slightly cold-worked material is age-hardened at 608°C (1125°F ) for 16 h followed by cooling in a furnace. Severely cold-worked material is aged at 538°C (1000°F) for 6 h followed by cooling in a furnace.

Super alloy Nickelvac K-500 is used in impellers, sea water pump shafts, and oil well industry for valve trim and other components.
