We can produce stainless steel investment castings using a wide selection of stainless steel alloys with great strength and resistance. Black oxide is a type of popular surface treatment for lost wax castings, to form an anti-rust layer on the metal parts to increase the durability and release of the stress of the casting, and also provides a smooth and glossy look. Black oxide investment casting parts are applied when a uniform black surface is needed, this coating is affordable and can add value to the casting part, but no obvious dimensional change. We can manufacture stainless steel casting for various industries, including auto parts, pipe fitting, metal brackets, fitting, key, pump body, and other types of custom lost wax castings.
