We can paint any color after shot blasting for steel forgings according to the colour palette or color chart (such as RAL 7016). If the steel forgings will be machined, then painting is usually operated before machining in case the machining surface will be effected.<\/p>\n<p><strong>Powder Coating<\/strong><\/p>\n<p>Powder coating is another surface treatment way for colors. Comparing with painting, it does less harm to the environment. But powder coating costs more than paiting. Also, the surface of steel forgings looks much better.<\/p>\n<p><strong><a href=\"http:\/\/www.steelforging.org\/wp-content\/uploads\/2017\/10\/Galvanization-for-steel-forging.jpg\"><img loading=\"lazy\" class=\"alignright wp-image-981\" src=\"http:\/\/www.steelforging.org\/wp-content\/uploads\/2017\/10\/Galvanization-for-steel-forging.jpg\" alt=\"surface treatment of steel forging\" width=\"269\" height=\"180\" srcset=\"https:\/\/www.steelforging.org\/wp-content\/uploads\/2017\/10\/Galvanization-for-steel-forging.jpg 388w, https:\/\/www.steelforging.org\/wp-content\/uploads\/2017\/10\/Galvanization-for-steel-forging-300x201.jpg 300w, https:\/\/www.steelforging.org\/wp-content\/uploads\/2017\/10\/Galvanization-for-steel-forging-230x154.jpg 230w, https:\/\/www.steelforging.org\/wp-content\/uploads\/2017\/10\/Galvanization-for-steel-forging-350x235.jpg 350w, https:\/\/www.steelforging.org\/wp-content\/uploads\/2017\/10\/Galvanization-for-steel-forging-272x182.jpg 272w\" sizes=\"(max-width: 269px) 100vw, 269px\" \/><\/a><a href=\"http:\/\/www.steelforging.org\/hot-dip-galvanization-for-steel-forgings\/\">Galvanization<\/a><\/strong><\/p>\n<p>Galvanization is the process of applying a protective zinc coating to steel forging, to prevent rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. There are two types of zinc used, one is trivalent zinc and the other is hexavalent zinc. Trivalent zinc is environmental, but cost more than hexavalent zinc. And hexavalent will do harm to the environment. So almost all the overseas customers prefer trivalent zinc for their high sense on environment.<\/p>\n<p><strong>Black Oxide Finish<\/strong><\/p>\n<p>Black oxide or blackening is a conversion coating for steel forgings. It is used to add mild corrosion\u00a0resistance, for appearance and to minimize light reflection. To achieve maximal corrosion resistance the black oxide must be impregnated with oil or wax. The obvious advantages over other coatings is its\u00a0minimal buildup. After black oxidization,the surface of steel forgings will look smooth and glossy. We will see an anti-rust layer,which is helpful to longer the lifetime of products.<\/p>\n<p><strong>Pickling and Passivation<\/strong><\/p>\n<p>Pickling &amp; passivation is a special surface treatment way only for stainless steel forging. Both pickling and passivation are chemical treatments applied to the surface of stainless steel forging to remove contaminants and assist the formation of a continuous chromium-oxide, passive film. Pickling and\u00a0passivation are both acid treatments and neither will remove grease or oil.<\/p>\n<p><strong>Phosphating Treatment<\/strong><\/p>\n<p>Phosphate coatings are used on steel forgings or castings for corrosion resistance, lubricity, or as a\u00a0foundation for subsequent coatings or painting. It serves as a conversion coating in which a dilute solution of phosphoric acid and phosphate salts is applied via spraying or immersion and chemically reacts with the surface of the part being coated to form a layer of insoluble, crystalline phosphates.<\/p>\n<p><strong>Case Hardening<\/strong><\/p>\n<p>Case-hardening is the process of hardening the surface of steel forging part while allowing the steel\u00a0deeper underneath to remain soft, thus forming a thin layer of harder metal (called the &#8220;case&#8221;) at the\u00a0surface. Case-hardening or surface hardening is the process of hardening the surface of a metal object\u00a0while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the &#8220;case&#8221;) at the surface.<\/p>\n<p>Our surface treatment capability enables\u00a0us to offer our customers high quality steel forgings with excellent surface finish after <a href=\"http:\/\/www.steelforging.org\/closed-die-forging\/\">closed die forging<\/a> process.
