ASTM A312 TP304 Stainless Hlau Seamless Yeeb, 304 Stainless Hlau Yeeb

Dab tsi yog 304 Stainless Hlau?

304 (tseem hu ua UNS S30400, 1.4301, SUS304) yog siv dav siv austenitic stainless hlau, muaj npe nrov rau kev ntsuas kev tiv thaiv corrosion, formability thiab nqi -effectiveness. Its chromium-nickel composition forms a dense passivation film on the surface, providing reliable protection in most common environments like fresh water and dry air.

Qib sib npaug

304 stainless hlau sib raug rau: UNS S30400 (American standard), JIS SUS304 (Japanese standard), GB 06Cr19Ni10 (Suav tus qauv) thiab EN X5CrNi18-10 (European standard).

 

Chemical Composition (wt%)

Cov pa roj carbon tsawg dua lossis sib npaug ntawm 0.08, Silicon Tsawg dua lossis sib npaug rau 1.00, Manganese Tsawg dua lossis sib npaug 2.00, Phosphorus Tsawg dua lossis sib npaug 0.045, Sulfur Tsawg dua lossis sib npaug 0.030, Chromium 18.00-20.00, Nickel-105. 0.10, Hlau (sib npaug).

 

Cov khoom tseem ceeb (20 degree, Annealed Condition)

Lub cev muaj zog: ntom 7.93g/cm³, melting point 1400-1450℃.Mechanical zog: Tensile zog 515-690N/mm², 0.2% yield zog Ntau tshaj los yog sib npaug zos rau 205N/mm², elongation Ntau tshaj los yog sib npaug zos rau 40%, los yog sib npaug rau H2. Less

 

Cov yam ntxwv tseem ceeb

Corrosion resistance: Zoo heev hauv dej tshiab, huab cua qhuav thiab tsis muaj zog acids, tab sis tsis tshua muaj kev tiv thaiv rau siab -chloride ib puag ncig piv rau 316.

Formability & weldability: Haum rau khoov, stamping thiab vuam yam tsis muaj preheating.

Tus nqi -kev ua tau zoo: Thawj qhov kev xaiv rau kev siv dav dav hauv pej xeem thiab kev lag luam nrog cov kev xav tau ntawm kev txhim kho corrosion.

Hardness & Ceev

Hardness: Tsawg dua los yog sib npaug rau 201HB hauv lub xeev annealed; Kev ua haujlwm txias tuaj yeem ua kom tawv tawv (txog 300HB), thiab annealing (1050-1100 degree) rov ua dua.

Ceev: 7.93g / cm³, zoo ib yam nrog rau lwm yam austenitic stainless hlau qib.

Qhov sib txawv ntawm 304 thiab 304L

Cov ntsiab lus sib txawv yog cov ntsiab lus carbon: 304 ( Tsawg dua lossis sib npaug li 0.08%) vs 304L ( Tsawg dua lossis sib npaug li 0.03%) . 304L zam kev sib xyaw ua ke tom qab vuam yam tsis muaj kev kho cua sov tab sis muaj zog tensile qis dua (485-650N/mm²). 304 welding{1} yog nyiam dua Cov xwm txheej, thaum 304L haum rau cov ntawv siv vuam siv.
