Quyma temir - uglerod miqdori 2% dan ortiq bo'lgan temir-uglerodli qotishma. Umuman olganda, biz ishlatadigan quyma temir klapanlar - bu kulrang quyma temir eritilgan temirni sferoidizatsiya qilish orqali olinadigan egiluvchan temir. Cho'kma grafit sferoidlar shaklida bo'lib, u egiluvchan temir deb ataladi. Oddiy kulrang quyma temirdan ko'ra yuqori mustahkamlik, yaxshi pishiqlik va plastiklikka ega.

Quyma temir klapanlar va quyma po'latdan yasalgan valflar o'rtasidagi farq nima?
The main difference between cast iron and iron steel valves is the carbon content, which directly affects the strength and plasticity of the steel. Carbon steel is also called carbon steel, an iron-carbon alloy with a carbon content of less than 2%. In addition to carbon, carbon steel generally contains small amounts of silicon, manganese, sulfur, and phosphorus. According to its use, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel, and free-cutting structural steel. Carbon structural steel is divided into two types: building structural steel and machine-made structural steel: according to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6% ) and high carbon steel (WC>0.6%. Fosfor va oltingugurt tarkibiga ko'ra, uglerod po'latini oddiy karbonli po'latga (yuqori fosfor va oltingugurt miqdori) va yuqori sifatli uglerodli po'latga (past fosfor va oltingugurt miqdori) va yuqori sifatli yuqori sifatli po'latga (pastki fosfor va oltingugurtni o'z ichiga olgan) bo'linishi mumkin. oltingugurt). Odatda, uglerodli po'latda uglerod miqdori qanchalik ko'p bo'lsa, qattiqlik va mustahkamlik shunchalik yuqori bo'ladi, lekin plastiklik past bo'ladi.
