420 / 420C polo uʻamea le silasila

SUS410 / SUS420J2 / SUS430 pa uʻamea le faʻatusatusaina：

SUS410: Martensite faʻatusa le sila uamea, ma maualuga maualuga ma maualuga maaʻa (maneta); leaga le pala, e le talafeagai mo le faʻaaogaina i ni siʻosiʻomaga faigata; maualalo mea C, lelei gaioiga, ma luga e mafai ona faʻamaʻaʻaina e le vevela togafitiga.

SUS420J2: Martensite faʻatusa le sila uamea, ma maualuga maualuga ma maualuga maaʻa (maneta); le lelei tetee palapala, leaga gaosi ma formability, ma lelei laei tetee; mafai ona vevela togafitia e faʻaleleia atili masini meatotino. E lautele faʻaaogaina mo le gaosia o naifi, nozzles, afuala, pule, ma meaʻai.

SUS430: Maualalo faʻalauteleina vevela fua faatatau, lelei faaleleia ma oxidation tetee. Fetaui lelei mo vevela-teteʻe masini, burners, mea faigaluega i le fale, vasega 2 meaʻai e faʻatutu i le umukuka. Tau maualalo, lelei gaioiga o se sui lelei mo SUS304; tetee lelei corrosion, masani lē-vevela togafitiga faʻamaʻaʻaina uʻamea stainless uʻamea.

Mataupu Faavae o le silasila uʻamea polo:

O lopa uamea e le o ni ele-faʻamaonia, ae le faigofie ona ele. O le faʻavae e ala i le faʻaopopoina o le chromium, o le mafiafia o le chromium oxide layer na faia i luga o le uʻamea, e mafai ai ona poloka poloka le toe faʻafesoʻotaʻi i le va o le uʻamea ma le ea, ina ia le okesene i le ea e le mafai ona ulufale i le sila. polo, ma puipuia ai le aafiaga o uʻamea lopa pala.

China National Standards (CNS), Japanese Industrial Standards (JIS) ma le American Iron and Steel Institute (AISI) o loʻo faʻaaogaina ni numera se tolu e faʻailoa mai ai eseʻesega uʻamea, o loʻo taʻua lautele i le pisinisi, o le 200 faʻasologa o le chromium-nickel-manganese -based austenitic Stainless steel, 300 series is chromium-nickel austenitic stainless steel, 400 series chromium stainless steel (e masani ona faʻaigoaina o le stainless iron), e aofia ai le martensite ma le ferrit.
