Cr-Mo steel is widely used in the world of heat-resistant steel and hydrogen steel. As in the low carbon steel by adding Cr, Mo and other alloying elements, greatly improving the overall performance of the steel. Such as good high temperature mechanical properties, high temperature oxidation resistance, corrosion resistance, good toughness, process performance and weldability, it is widely used in the manufacture of petrochemical, coal conversion, nuclear power, steam turbine, thermal power and other conditions Harsh, corrosive medium complex large equipment. In the past most of this type of steel dependent on foreign imports. Katalor company as a domestic research and production base of heavy plate, in order to break the monopoly of foreign countries, the revitalization of national industry, to achieve a Cr-Mo steel plate of the localization.

15CrMoR development process:
Oil and gas industry, petrochemical industry, chemical equipment manufacturing enterprises, power plant construction, boilers and pressure vessel manufacturing and other enterprises and Katalor production 15CrMoR for the production reactor, heat exchanger, separator, spherical tank, gas tank, gas tank, nuclear reactor pressure Because the petrochemical, coal conversion, nuclear power, steam turbine block, thermal power and other harsh conditions of use, which corrosive medium complex large equipment such as: washing tower, the second converter, coke tower, gas turbine, The use of 15CrMoR or 15CrMoR hydrogen in the production of equipment and components such as desulfurization tank, conversion gas waste heat boiler, methanation furnace, reactor, regenerator, hydrogenation reactor, methanation heater, conversion gas steam generator, 15CrMoR (H) plate million tons. In the United States, Canada, Australia, India, Europe's prospects for a good. Has been direct supply to customers in Europe more than 20,000 tons.
