ASTM A283 Qib C ASTM A283 / A283M Tshuaj lom neeg
Carbon, Silicon, Manganese, Phosphorus, Sulfur yog hu ua "Tsib Elements". Lawv yog cov impurities tseem ceeb hauv steel. Carbon txhim kho steel hardness. Silicon ntxiv dag zog rau cov hlau. Manganese pab txhawb kom cov hlau ruaj khov, lub zog thiab hnav tsis kam. Phosphorus txo cov hlau plasticity thiab toughness thiab tshwm txias brittleness. Lub caij no, Nws tuaj yeem ua kom muaj zog ntawm cov hlau, thiab txhim kho atmospheric corrosion stability. Sulfur ua rau kub brittleness ntawm steel siab.
