II. Saray Manunan Bentaha: Ag-ontutulong ed Petang, Ag-ontutulong tan Ag-onkupas
1. Ekselentin Atagey-Temperaturan Inkapekder tan Ag-onkukurang
Say temperatura na serbisyo ed andukey a panaon et anggad 900 degree, say peak ed antikey a panaon et anggad 1000 degree.
Atagey a biskeg na panag-creep tan panag-apag ed silong na atagey-temperatura tan ambelat-kondisyon na karga; anggapoy deformation o sagging legan na andukey a panaon ya pangusar.
Makapadinayew ya resistensya ed pakapoy tan ag-onkapuy ed petang, ya matukoy ed mabetbet ya panagpainit tan panagpabetel.
2. Mas maabig ya Resistansi ed Pan-upot tan Pan-erosion
Say carbide strengthened phase ya walay high hardness matrix (HB 180-220) et mas maong so resistensya to nen say ordinaryon heat-resistant steels diad silong na atagey a temperatura na dry friction tan particle erosion, ya mamaawang na 2-3 danay.
Say makapal ya surface oxide film et mangiiter na self-lubricating effect, ya mamapaabeba ed materyal ya adhesion tan abrasion, ya maabig parad saray grates, liner plates, basket tan arum niran wear-prone ya parte.
3. Komprehensibon Panangilaban ed Kabulok
Maong ya resistensya ed atagey ya temperatura na sulfur-, chlorine-, dabok- ya karga na flue gas tan slag corrosion.
Epektibon makaresisti ed atagey a temperatura na oxidation, sulfidation corrosion tan erosion corrosion.
Maong ya resistensya ed panag-apag na asido tan alkali parad atagey a temperatura ya makaderal iran kaliberliber diad saray industriya na kemikal tan proteksion na kaliberliber.
4. Maong ya Casting tan Machining Adaptability
Maong ya fluidity na austenitic matrix, ekselentin precision casting performance parad saray komplikadon kabiangan a singa say espisyal ya kurti na grates tan saray pinagkasakey a liner plates.
Naabobonan so weldability tan machinability parad kombenientin on-site ya pangipuesto, pangapiger tan pangi-adjust.
III. Kaslakan ya Aplikasyon (Core High-Temperature & Wear-Resistant Fields)
