\/>\n<meta property=\"og:description\" content=\"Casting valves are valves made by casting. Generally, the pressure grades of cast valves are relatively low (such as PN16, PN25, and PN40, but there are also high-pressure ones, which can reach 1500Lb, and 2500Lb), and most of their calibers are above DN50. Forged valves are forged and are generally used in high-grade pipelines with relatively small diameters, generally below DN50.   GET DIFFERENCE BETWEEN CAST AND FORGED IRONS INFORMATION  Why use Castings?  We use castings for a wide range of wear parts and components that are too large, complicated, intricate, or otherwise unsuitable for the forging process. We can forge parts up to 50kgs but the sheer energy required to forge larger items makes casting a much more viable alternative.  Advantages of Castings   No real upper size limit in casting weight  Large range of alloy choices  As forgings remain solid, custom alloys are far more difficult to get into production whereas, with casting, alloys including Chrome, Nickel, and Moly can be added at the molten stage.  Tooling is often less expensive than forge dies  Smaller production \u201cruns\u201d required  Complicated\/complex parts are no problem  Why use Forgings?  Forging offers uniformity of composition and structure. Forging results in metallurgical recrystallization and grain refinement as a result of the thermal cycle and deformation process. This strengthens the resulting steel product, particularly in terms of impact and shear strength.  Forged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel\u00a0are altered, conforming to the shape of the part.  Advantages of Forgings   Generally tougher than alternatives  Will handle impact better than castings  The nature of forging excludes the occurrence of porosity, shrinkage, cavities, and cold pour issues.  The tight grain structure of forgings makes them mechanically strong. There is less need for expensive alloys to attain high-strength components.  The tight grain structure offers great wear resistance without the need to make products \u201csuperhard\u201d We have found that on a blank HRC 38-42 forged grinder insert wear\/wash is about the same as a high alloy HRC 46-50 cast grinder insert. The difference being an HRC 46-50 casting does not have the ductility to handle high-impact grinding.  Difference Between Cast and Forged Irons  Casting valve: the metal is smelted into a liquid that meets the requirements and poured into the specified valve mold. After cooling, solidification, and cleaning, a valve casting with a predetermined shape, size, and performance can be obtained. This is the entire casting valve crafting process. The connection between casting and valves came after the 20th century. Casting developed rapidly, creating ductile cast iron, malleable cast iron, ultra-low carbon stainless steel, aluminum copper, aluminum silicon, aluminum-magnesium alloy, and titanium which are still often used in valve products.  Cast metal materials such as base, nickel base alloy, etc. The main advantage of casting is that the cost of the blank produced by casting is low, and it can show its economy more for parts with complex shapes, especially with complex inner cavities. At the same time, it has wider adaptability and better comprehensive mechanical properties. However, many materials and equipment are required for casting production, and dust, harmful gases, and noise will be generated to pollute the environment.  Forged valve is a processing method that uses forging machinery to apply pressure to metal valve blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and sizes. Forging can be divided into open forging (free forging) and closed mode forging according to the forming method. According to the deformation temperature, forging can be divided into hot forging, warm forging, and cold forging.  Forging materials are mainly carbon steel and alloy steel with various compositions, followed by aluminum, magnesium, titanium, copper, etc., and their alloys. The original state of the material includes bar stock, ingot, metal powder, and liquid metal. The ratio of the cross-sectional area of the metal before deformation to the die cross-sectional area after deformation is called the forging ratio. Through forging, the as-cast looseness of metal and welding holes can be eliminated, and the mechanical properties of forgings are generally better than those of castings of the same material. For the important parts of machinery with high loads and severe working conditions, forgings are mostly used except for simpler shapes that can be rolled, profiles or welded parts. The correct selection of forging ratios has a great bearing on improving product quality and reducing costs.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/ru\/tag\/difference-between-forged-and-cast\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebSite\",\"@id\":\"https:\/\/zecovalve.com\/#website\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"ZECO Valve\",\"description\":\"Industrial Ball Valve, Gate Valve and Globe Valve Manufacturer\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":\"https:\/\/zecovalve.com\/?s={search_term_string}\",\"query-input\":\"required name=search_term_string\"}],\"inLanguage\":\"ru-RU\"},{\"@type\":\"CollectionPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast\",\"name\":\"Difference Between Forged and Cast Irons Valve | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast#breadcrumb\"},\"inLanguage\":\"ru-RU\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"Home\"}},{\"@type\":\"ListItem\",\"position\":2,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast\",\"url\":\"https:\/\/zecovalve.com\/tag\/difference-between-forged-and-cast\",\"name\":\"Difference Between Forged and Cast\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/ru\/wp-json\/wp\/v2\/tags\/3265","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/ru\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/zecovalve.com\/ru\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/ru\/wp-json\/wp\/v2\/posts?tags=3265"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
