1.4301 Stainless hlau yog dab tsi?

1.4301 stainless hlau, universally lees paub tias yog hom 304 los yog UNS S30400, yog cov feem ntau siv austenitic stainless hlau. Nws qhov sib npaug ntawm chromium thiab npib tsib xee muab kev sib xyaw ua ke zoo heev ntawm kev tiv thaiv corrosion, formability, thiab weldability, ua rau nws tus qauv kev xaiv rau ib tug loj array ntawm daim ntaub ntawv los ntawm chav ua noj dab dej thiab architectural trim rau tshuaj ntim thiab khoom noj khoom haus. Raws li qib benchmark austenitic, nws sawv cev kwv yees li 50% ntawm tag nrho cov hlau tsis muaj steel uas tsim tawm thoob ntiaj teb.

 

Cov qhab-nees hauv paus no yog txhais thoob plaws txhua tus qauv loj thoob ntiaj teb.

EN (Tebchaws Europe)	1.4301
ASTM / AISI (USA)	304, UA S30400
JIS (Nyiv)	SUS 304
KS (Korea)	STS 304

Nws qhov kev ua tau zoo txhim khu kev qha stems los ntawm classic thiab zoo - cov tshuaj muaj pes tsawg leeg.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4301 / 304

Zoo heev General Corrosion Resistance:Ua tau zoo tiv thaiv ntau qhov chaw ntawm huab cua, dej tshiab, khoom noj khoom haus, thiab ntau yam tshuaj organic thiab inorganic.

Superior Forming thiab Welding:Exhibits zoo ductility rau sib sib zog nqus nqus, dabtsi yog khoov, spinning, thiab lwm yam kev ua hauj lwm. Nws yog yooj yim weldable los ntawm tag nrho cov qauv fusion txoj kev.

Hygienic thiab Aesthetic Appeal:Nws tsis yog - ntxeem tau qhov chaw yog yooj yim los ntxuav thiab huv, thiab nws tuaj yeem polished rau ntau yam tiav, ua rau nws zoo tagnrho rau kev sib cuag zaub mov thiab siv cov hniav zoo nkauj.

Zoo heev Toughness:Ua kom muaj kev cuam tshuam zoo heev rau qhov kub thiab txias, ua rau nws tsim nyog rau kev siv qis - kub.

 

Cov ntawv thov tseem ceeb:

Cov khoom siv:Chav ua noj dab dej, khoom siv, cookware, cutlery, thiab tableware.

Architecture & Kev tsim kho:Handrails, qhov rooj thiab qhov rais fittings, phab ntsa cladding, ru tsev, thiab structural seem.

Khoom noj khoom haus & dej haus kev lag luam:Tank, vats, piping, brewing khoom, thiab conveyor systems.

Kev lag luam tshuaj:Lub tank cia thiab cov kav dej rau cov corrosive me me.

Automotive:Trim, grilles, thiab cov khoom tso tawm.

Dab tsi yog qhov txawv ntawm 304 (1.4301) thiab 304L (1.4307)?
Qhov sib txawv tseem ceeb yog cov ntsiab lus carbon. Standard 304 muaj cov ntsiab lus siab tshaj plaws ntawm 0.07%, thaum 304L (Low Carbon) muaj qhov siab tshaj plaws ntawm 0.03%. Qhov qis carbon cov ntsiab lus hauv 304L txo qis qhov tsim ntawm chromium carbides thaum vuam, yog li tswj kev tiv thaiv rau intergranular corrosion nyob rau hauv "raws li -welded" mob. Rau cov ntawv thov uas muaj cov vuam hnyav uas tsis tuaj yeem tshaj tawm -weld kub kho, 304L yog qhov zoo dua. Rau feem ntau cov ntawv thov tsis cuam tshuam nrog cov vuam hnyav, tus qauv 304 yog qhov tsim nyog thiab raug nqi - zoo.

 

304 stainless hlau puas tuaj yeem siv rau hauv kev ua zaub mov?
Yog, 304 yog cov khoom siv rau kev ua zaub mov thiab khoom siv. Nws tsis yog - ntxeem tau qhov chaw tiv thaiv kab mob loj hlob, nws tsis muab saj los yog tsw rau cov khoom noj, thiab nws tiv taus ntau zaus ntxuav thiab ntxuav nrog tshuaj me me. Nws yog dav siv rau cov khoom noj khoom haus tso tank, countertops, khoom siv hauv chav ua noj, thiab cov tshuab ua zaub mov. Nws ua raws li cov cai ntawm kev sib cuag zaub mov hauv ntau lub teb chaws ua rau nws cov khoom xaiv rau kev lag luam khoom noj.
