Monel plate
What is Monel Plate ?

Monel is a nickel and copper alloy that is known for its excellent corrosion and temperature resistance. The monel plates are highly recommended for industries like marine and chemical processing. There are different grades of monel with varied properties like 400, R-405 and K-500.

The first two grades have similar mechanical properties but R-405 has higher sulphur content and hence is easier to machine. K-500 has added aluminium and titanium which improves its mechanical strength.

The monel plate suppliers recommend the products for its high strength and capability of withstanding both fresh and seawater. The material can also resist low and high temperature environments. Apart from these, the k-monel plate also shows good formability and it can be welded using standard techniques.

We are most trustworthy monel sheet supplier in India according to ASTM B127, check can I use it for applications involving seawater?

Can i used Monel sheet in seawater application?

One of the reasons why the monel sheet price is relatively high is its chemical composition and properties like extreme resistance to seawater environment. However, if the sheet is used with metals like steel, aluminum, iron or zinc, proper precautions must be taken. Or else, galvanic corrosion might occur which will cause the other material than monel to corrode.

What is Monel sheet metal working temperature range ?

A properly treated monel sheet metal has good mechanical properties from subzero to 480 °C. The material comes with a melting point of 1300-1350 °C. However, the specific working temperature would vary with the specific monel grade.

The 400 grade can withstand a temperature range of -100 to 538 °C, while for the k-500 grade, the temperature range is -100 to 650 °C. However, in the case of r-405, the low max operating temperature is 315 °C.

What property make Monel alloy plate expensive ? what is it price in India ?

The monel alloy plate alloy has a high nickel and chromium content, which increases the price of the metal. Compared to copper and nickel, the monel sheet price is around five times more expensive. It is thrice as expensive as normal carbon or stainless steel material.

The exact price of the plate in India will depend on its specific grade and market demand-supply conditions. The price also varies with the supplier depending on their internal costings and requirements like sizes, surface finish and delivery location. If you want high quality monel polished plate at the best price, contact top suppliers in India like Regent Steel & Engineering Co.

Is Monel Coil is hard to machine ? why?

Monel coil is hard to machine as it tends to work harden very quickly. This is why, machining must be done by experienced professionals, whom you can get at Regent Steel & Engineering Co.

How should i identify Monel plate steel ?

To identify monel plate steel, you must look at the markings and labels present on it. You can also perform a chemical composition analysis or get a material test certificate to ensure the material grade.

Finally, get the plates from a reputed supplier like Regent Steel & Engineering Co. to ensure the plate integrity and quality.
