15Mo3 steel manufacturing method: adopt oxygen top blown converter method, 182 open hearth method or 3666 to smelt in 3769 electric furnace. After negotiation with the customer, other equivalent methods can also be adopted.
15Mo3 steel is used for heating surface pipes, economizers, superheaters, reheaters, etc. of high-pressure boilers (working pressure is generally above 9.8MPa, working temperature is between 450 ℃ ~ 650 ℃).BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.KB grab dredger steel,The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
KB grab dredger steelThe purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels,KB grab dredger steel.KB grab dredger steel,Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, steel sheets, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding.
