2) Oil Exploitation:Such as drill pipes, drill bits, oil production platforms, etc.
3) Pharmaceutical Equipment:Such as reactors, storage vessels, transportation pipelines, etc.
4) Food industry: such as production lines for canned food, beverages, dairy products, etc.
V.1The smelting process of 4547
1.The smelting process of 4547 mainly includes the following steps:
1) Ironmaking:Iron ore is smelted in a blast furnace to obtain molten iron.
2) Steelmaking:The molten iron is deoxidized and alloyed by converter, electric arc furnace and other equipment to obtain molten steel that conforms to the composition.
3) Continuous Casting:The molten steel is cast into slabs or round bars through a continuous caster.
4) Rolling:The continuous casting billet is processed into the required plates, round bars, seamless pipes and other products through hot rolling, cold rolling, cold drawing, etc.
5) Heat Treatment:The rolled product is treated with solution treatment, pickling, brightening, etc., to improve its performance.
VI.1Metallographic structure and material structure of 4547
1.The metallographic structure of 457 stainless steel is mainly austenitic and contains an appropriate amount of carbides and sulfides. The material structure is that a large number of nickel and chromium atoms are distributed on the ferrite matrix, forming a stable austenite phase. Casting and forging of 454 stainless steel.
1.Casting and forging of 4547 are two different metal forming processes. Casting is the process of melting metal and pouring it into a mold, cooling and solidifying it; Forging is the process of heating metal to a high temperature and plastically deforming it by hammering or pressing. Compared with casting, forging can improve the mechanical properties and machining accuracy of materials.
VIII.1Cold-rolled, hot-rolled and cold-drawn of 4547
1.Cold rolling, hot rolling, and cold drawing of 4547 are three different rolling processes. Hot rolling is the rolling of metals at high temperatures, so that they produce plastic deformation; Cold rolling is the rolling of metal at room temperature to produce plastic deformation; Cold is the stretching of metal at room temperature to cause plastic deformation. These three processes can be used to produce14547 plates, seamless pipes and other products.
