Is cóimhiotal iarainn-charbóin é iarann teilgthe le cion carbóin níos mó ná 2%. Go ginearálta, is iarann insínte iad na comhlaí iarann teilgthe a úsáidimid, a fhaightear trí iarann leáite d'iarann teilgthe liath a spheroidizing. Tá an graifít deasctha i bhfoirm sféaróid, dá ngairtear iarann insínte. Tá neart níos airde, toughness agus plaisteacht níos fearr aige ná gnáth-iarann teilgthe liath.

Cad é an difríocht idir comhlaí iarann teilgthe agus comhlaí cruach teilgthe?
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%. De réir an t-ábhar fosfar agus sulfair, is féidir cruach carbóin a roinnt ina ghnáth-chruach carbóin (cion fosfar agus sulfair níos airde) agus cruach carbóin ard-chaighdeán (ábhar fosfar agus sulfair níos ísle) agus cruach ard-chaighdeán ard-ghrád (ina bhfuil fosfar níos ísle agus sulfair). Go ginearálta, dá airde an t-ábhar carbóin i cruach carbóin, is airde an cruas agus an neart, ach an plasticity níos ísle.
