Basic Compositional yam ntxwv
Cov ntsiab lus carbon: Feem ntau nyob rau hauv nruab nrab- carbon ntau (0.3%–0.6% los ntawm huab hwm coj), tawm tsam qhov sib npaug ntawm lub zog, hardness, toughness, thiab hardenability.
Alloying Elements: suav nrog cov ntsiab lus xws li Cr, Mn, W, Mo, thiab V los ua haujlwm tshwj xeeb, xws li ntxiv dag zog rau cov ferrite matrix, txhim kho hardenability, txhawb nqa cov hardening theem nrab, thiab txhim kho oxidation kuj.
Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm
High -Tsub Mechanical Properties: Khaws lub zog siab ntawm qhov kub ntawm 400℃thiab 700℃; withstands siab siab thiab cuam tshuam loads thaum resisting yas deformation.
Kev Ruaj Ntseg Zoo Tshaj Plaws: Cov cuab yeej cuab tam ntawm chav tsev kub tsis tuaj yeem txo qis tom qab lub sijhawm ntev ntawm qhov kub thiab txias, tiv thaiv pwm tawg lossis kev ua haujlwm tsis zoo.
Siab Thermal Fatigue Resistance: Nrog rau kev rov ua cua sov dua - lub voj voog txias thiab txo qhov tsim ntawm lub network nto - zoo li thermal qaug zog tawg, ua rau nws tsim nyog rau kev khiav hauj lwm cuam tshuam nrog ceev thermal cycling.
High Wear Resistance: Retains high deg hardness nyob rau hauv siab -kev sib txhuam kub, tiv taus hnav, oxidative corrosion, thiab abrasion los ntawm kub hlau thiab hlau oxide nplai.
Zoo Hardenability: Ua kom cov khoom siv sib xyaw ua ke thoob plaws tag nrho tus ntoo khaub lig- ntu ntawm cov tuag loj, tiv thaiv cov khoom tsis zoo.
Zoo Thermal Conductivity: sai sai dissipates tshav kub accumulated nyob rau hauv lub tuag, txo qhov kub ntawm qhov chaw thiab txo thermal stress concentrations tshwm sim los ntawm sab hauv kub gradients.
Oxidation thiab Corrosion Resistance: Resistant oxidation txheej tsim nyob rau hauv high kub thiab withstands thermal yaig los ntawm molten hlau, yog li ncua lub tuag cov kev pab cuam lub neej.
