304 uye 316 mhando dzesimbi isina tsvina, uye "kupera" kwavo kunoreva kutaridzika kwepamusoro kana kutaridzika kwesimbi. Musiyano uripo pakati pemhando mbiri idzi unonyanya kuve mukuumbwa kwavo uye zvinokonzeresa zvinhu:

Kuumbwa:

304 Stainless Simbi:

Iine inenge 18-20% chromium uye 8-10.5% nickel.
Inogonawo kunge iine zvidiki zvezvimwe zvinhu senge manganese, silicon, uye kabhoni.

316 Stainless Simbi:

Iine inenge 16-18% chromium, 10-14% nickel, uye 2-3% molybdenum.
Kuwedzerwa kwe molybdenum kunowedzera kuramba kwayo mukuora, kunyanya kupesana nemakloridi uye mamwe maindasitiri anonyungudutsa.

Properties uye Applications:

304 Stainless Simbi:

Corrosion Resistance: Zvakanaka, asi kwete kusvika pa316, kunyanya munzvimbo dzechloride.

Simba: Simba repamusoro uye kuoma, zvakanaka kune zvinangwa zvakajairika.

Applications: Inoshandiswa zvakanyanya mumidziyo yekubikira, kugadzira chikafu, dhizaini yekuvaka, midziyo yemakemikari, uye nezvimwe nekuda kwekunaka kwayo kushora uye nyore kuchenesa.

316 Stainless Simbi:

Corrosion Resistance: Kupfuura 304, kunyanya mumvura yemunyu kana mugungwa, uye pamberi pemakloridi.

Simba: Zvakafanana ne304 asi nekuramba kuri nani kwegomba.

Applications: Yakanakira kushandiswa munzvimbo dzemugungwa, midziyo yemishonga, maimplants ekurapa, kugadzirisa makemikari, uye chero nharaunda inokwirisa corrosion inodiwa.

Pedzisa:

"Kupera" kwesimbi isina tsvina, ingave 304 kana 316, inoreva kupera kwepamusoro, iyo inogona kusiyana zvichienderana nekugadzirwa kwekugadzira. Zvinowanzopedzisa zvinosanganisira:

1, Kwete. 2B: Kupedzwa kwakapfava, kwakagomara kunogadzirwa nechando kukunguruka kunoteverwa neannealing uye kudzika.

2, Kwete. 4: Mhedzisiro yebrashi, iyo inowanikwa nemuchina kukwesha pamusoro kuti igadzire patani yemitsara yakanaka inofambirana negwara rekukwesha.

3, Kwete. 8: Mhedziso yakaita segirazi inogadzirwa nekukwenenzverwa nemaabrasives anoteedzana akakwenenzverwa uye kubhuroka.

Ese ari maviri 304 uye 316 simbi isina tsvina anogona kuve nekupedza kwakafanana, asi kusarudzwa pakati pe304 ne316 kuchaenderana nemamiriro ezvakatipoteredza uye zvivakwa zvinodiwa pakushandisa.

Ko 316 kana 304 inodhura?

Kazhinji, 316 simbi isina tsvina inodhura kupfuura 304 simbi isina tsvina. Chikonzero chikuru chekusiyana kwemutengo uyu ndiko kuumbwa kwesimbi isina tsvina ye316, iyo inosanganisira chikamu chepamusoro che nickel uye kuwedzera kwe molybdenum. Zvinhu izvi zvinosimudzira kuramba kwecorrosion kwe316 simbi isina tsvina, kunyanya munzvimbo dzechloride uye dzemugungwa, asi zvinopawo kumutengo wepamusoro wezvinhu.

Heino pfupiso yezvinhu zvinokonzeresa mutsauko wemutengo:

Kuumbwa Kwezvinhu:

304 Stainless Simbi: Iine inenge 18-20% chromium uye 8-10.5% nickel.
316 Stainless Simbi: Iine inenge 16-18% chromium, 10-14% nickel, uye 2-3% molybdenum.

Corrosion Resistance:

316 Stainless Simbi: Inopa hukuru hwekusaita ngura, kunyanya kurwisa ma chlorides uye munzvimbo dzemugungwa, nekuda kwekuvapo kwe molybdenum.
304 Stainless Simbi: Ine yakanaka corrosion resistance asi haishande munzvimbo dzine corrosion zvakanyanya zvichienzaniswa ne316.

Kugadzira Mari:

Huwandu hwepamusoro hwe nickel uye kuwedzera kwe molybdenum mu 316 simbi isina tsvina inokonzeresa kuwedzera mari yemidziyo.
Magadzirirwo uye mitengo yekugadzira inogona zvakare kukwira kune 316 simbi isina tsvina nekuda kwekuoma kwayo kuumbwa kwealloy.

Nokudaro, kune zvikumbiro apo kupikisa kwepamusoro-soro kwe316 simbi isina tsvina isingadiwi, 304 simbi isina tsvina inowanzosarudzwa seimwe nzira inodhura.
