Intshayelelo
Iintsimbi ezingenastainless zaziwa njengeentsimbi eziphezulu zealloy. Zihlelwe zibe yi-ferritic, austenitic, kunye neentsimbi ze-martensitic ngokusekelwe kwisakhiwo sabo se-crystalline.
IBanga le-310S insimbi engenasici iphezulu kune-304 okanye i-309 yensimbi engenasici kwiindawo ezininzi, kuba inomxholo ophezulu we-nickel kunye ne-chromium. Inokumelana ne-corrosion ephezulu kunye namandla kumaqondo okushisa ukuya kwi-1149 ° C (2100 ° F). Le datha ilandelayo inika iinkcukacha ezithe vetshe malunga nebakala 310S intsimbi engatyiwayo.

Ukwenziwa kunye noNyango loBushushu
Ubuchule
IBanga le-310S insimbi engenasici inokwenziwa ngoomatshini abafana nebanga le-304 yensimbi engenasici.
Ukuwelda
IBanga le-310S insimbi engenasici inokudityaniswa kusetyenziswa ukudibanisa okanye iindlela zokumelana ne-welding. Indlela ye-welding ye-Oxyacetylene ayikhethwanga kwi-welding le ngxube.
Ukusebenza okushushu
IBanga le-310S insimbi engenasici inokutshisa emva kokufudumeza kwi-1177°C (2150°F). Akufunekanga yenziwe ngaphantsi kwe-982°C (1800°F). Ipholiswa ngokukhawuleza ukwandisa ukuxhathisa umhlwa.
Ukusebenza Okubandayo
IBanga lama-310S intsimbi engenastainless inokufakwa intloko, iphazamiseke, izotywe, kwaye ifakwe isitampu nangona inomsebenzi ophezulu wokuqina. I-Anealing yenziwa emva kokusebenza okubandayo ukwenzela ukunciphisa uxinzelelo lwangaphakathi.
Ukuhlaziya
IBakala 310S insimbi engenasici ifakwe kwi-1038-1121°C (1900-2050°F) kulandele ukucima emanzini.
Ukuqina
IBakala 310S insimbi engenasici ayiphenduli kunyango lobushushu. Amandla kunye nobunzima bale alloy kunokunyuswa ngokusebenza okubandayo.
Usetyenziso
IBakala 310S insimbi engenasici isetyenziswa kwezi zicelo zilandelayo:
I-boiler baffles
