Advantages of molybdenum circles
Such a range can withstand large mechanical loads at temperatures above 1000 °C. It is distinguished heat resistance, heat resistance and corrosion resistance. It is stable in many corrosive environments, solutions of concentrated alkalis and acids — hydrochloric, H2 SO4, HF. Molybdenum and its alloys have high elastic modulus and low coefficient of thermal expansion. Because this metal is almost a half lighter than tungsten, up to 1370 °C Mo is more specific strength. Titanium molybdenum alloys can easily tolerate heat up to 1500 °C. molybdenum Round marks MCH, MS, MK (molybdenum doped silicon) operated at t° above 2000 °C. Molybdenum circle marks PM, MRN, molybdenum with a silica-doped, high t° recrystallization and a high bending strength and tension in the annealed condition. Alloying with cobalt increases the ductility of molybdenum in the annealed condition.

The main drawback is a significant cost of production. Molybdenum is a rare metal, it is difficult to distinguish in a pure form, it is refractory and difficult treatment, non-plastic at a low temperature. He gives the alloy hardness, however, increases the brittleness of the metal. Pure molybdenum is much heavier than iron and steel.
The scope of application of molybdenum circle is related to its resistance and durability in aggressive environments.
