310S Stenles Sil
Steinles Stil 310S em i wanpela hai-}kromium, hai-}nikel austenit steinles stiel i gat nem long eksepsenel hai- bilong taim bilong oksidesen na gutpela mekanik stebiliti aninit long ol ekstrem thermal kondisen. Olsem wanpela low-}carbon varien bilong 310 gret, em i spesifik enjinia long kamap gutpela long kontinu hai- temperature sevis, na mekim em i kamap wanpela nambawan mak bilong ol aplikesen we i gat longpela taim long kisim bikpela hat na ol envairomen i save bagarapim ol samting.

Samting
Steinles Stil 310S i gat dinau long wok bilong em long spesel kemikel komposesen bilong en. Wetem 24-6% kromium, hem i fomem wan protektiv oksaed leja, i mekem sua se i gat gudfala hae-tempereja oksidesen resistens. 19-22% nikel konten i mekim na ol i strongim wok bilong en, na dispela i strongim wok bilong en na strong bilong daunim strong bilong hat. Loa bilong en i no gat planti kabon (maks 0.03%) i pasim rot bilong wara i no ken ron gut, na dispela i daunim ol hevi bilong korosen i save kamap namel long ol diwai.
Long saed blong ol mekanik samting, 310S i moa gud truaot long ol tempereja. Long ol kondisen bilong ambient, em i gat minimam tensil strong bilong 515 MPa na givim strong bilong 205 MPa, wantaim 40% elongasen long taim bilong malolo. Notably, em i holim strong na krip resistens antap long 1000 digri , i winim planti wanlain.
Korosen resistens i makim 310S. Em i save sanap strong long yusim i go inap long 1150 digri na ol i save kisim ol samting i save kamap namel long 1200 digri na i no gat bikpela oksidesen. Em i save sakim ol ples bilong salfa na ol indastrial korosiv gut, maski klorait pitting resistens bilong en i wankain olsem 304. daunbilo kabon bilong em i larim weldim i no gat pos-weld annealing, na lukautim strong bilong en long daunim korosen.
