Boiler thiab Pressure Vessel SteelKhoom Taw Qhia
Qhov ntxov tshaj plaws kev lag luam boilers tau ua los ntawm cov hlau cam khwb cia, cov khoom siv dav siv ua ntej kev lag luam kiv puag ncig. Los ntawm lub xyoo pua puv 19, engineers pib sim nrog lwm cov ntaub ntawv hauv kev rau siab los tsim cov boilers uas tuaj yeem ua haujlwm ntawm qhov kub thiab txias. Qhov kev tshawb nrhiav no coj mus rau kev txhim kho cov chav kawm tshiab ntawm cov hlau hu ua boiler steel.

GB 12Cr1MoVR GB 713 Chemical element
GB 12Cr1MoVR GB 713 chemical muaj pes tsawg leeg muaj qhov tseem ceeb ntawm GB 12Cr1MoVR GB 713 cov khoom siv tshuab. Ntawm tag nrho cov GB 12Cr1MoVR GB 713 hais. Carbon yog hardening keeb. Silicon pab txhawb lub zog. Manganese yog qhov tseem ceeb ntawm austenite stabilizing cov ntsiab lus pab txhawb kev tsim cov qauv kev ntxhib los mos thiab ua kom muaj zog, lub zog thiab hnav tsis kam. Phosphorus txo cov 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.
