Qhov sib txawv ntawm ASME SA537 / SA537M chav kawm 1, Chav Kawm 2, thiab Chav 3 Siab Hlab Hlau Hlau Hlau

1.} Cov Khoom Siv Neeg Kho Tshuab

Hom	Peple zog (Min, MPA)	Tensile lub zog (mpa)	Elongation (% hauv 200 hli)
Hoob 1	Ntau dua los yog sib npaug rau 345	485 – 620	Ntau dua los yog sib npaug rau 18
Hoob 2	Ntau dua los yog sib npaug rau 415	550 – 690	Ntau dua los yog sib npaug rau 18
Hoob 3	Ntau dua los yog sib npaug rau 450	585 – 725	Ntau dua los yog sib npaug rau 18

Sau ntawv:

Chav kawm 1: Haum rau cov ntawv thov tsawg rau-nruab nrab nruab nrab .

Chav kawm 2 & 3: lub zog siab dua rau kev xav tau siab lossis lub teeb yuag lossis lub luag nyuaj tsim.

2.} tuab ntau yam

Hom	Thickness ntau (mm)	Cov Kev Siv Raug Raug
Hoob 1	Mus txog 200	Tso Tsheb Hlau Luam, Boilers (Aphient / Low Temps)
Hoob 2	Mus txog 200	Nruab nrab-siab cov hlab ntsha, reactors
Hoob 3	Txog li 150	Kev kub siab / qis-temp (e {{2} g .}}, lng tso tsheb hlau luam)

Sau ntawv:

Chav kawm 3 muaj stricter thickness txwv tab sis zoo tshaj qhov kev kawm kub tsawg dua.

3. kev kho cua sov

Hom	Kev ua	Kev tsim
Hoob 1	Li no	Ferrite + PETLLITE
Hoob 2	Queny & Temper (Q & T)	Tempered Bainite / Martensite
Hoob 3	Queny & Temper (Q & T)	Nplua-grained, high-tofial

Sau ntawv:

Q & T rau Chav Kawm 2/3 txhim kho lub zog thiab tawv .

4. qis-kub cuam tshuam tawv

Hom	Qhov ntsuas kub ntau	Charpy v-notch cuam tshuam lub zog (-45 degree)
Hoob 1	Ntau dua los yog sib npaug rau -30 degree	Tsis teev (rooj plaub-nyob)
Hoob 2	Ntau dua los yog sib npaug rau -45 degree	Ntau dua los yog sib npaug rau 20 j (transverse patchen)
Hoob 3	Ntau dua los yog sib npaug rau -60 degree	Ntau dua los yog sib luag rau 27 j (transverse patchen)

Sau ntawv:

Chav kawm 3 yog qhov zoo tagnrho rau kev siv cryogenic (e .}}}, lng cia).

Hoob 1:

Siv rau tus nqi tsawg, cov nkoj dav dav (ambient rau -30 degree) {3} {3}

Cov txiaj ntsig: Yooj yim tshav kev kho cua sov (li qub), yig .

Hoob 2:

Siv rau nruab nrab-siab los yog {{-45℃ib puag ncig (e {}}}}}}} {{4}

Cov txiaj ntsig: Ntsuas Ntsuas kom muaj zog-tawv ratio.

Hoob 3:

Siv rau kev kub siab los yog cryogenic system (e .}} {} degree).

Cov txiaj ntsig: Tshwj xeeb qis-temp todlight, tab sis siab dua tus nqi .

6. kev txiav txim siab tseem ceeb

Hwj txwv: Chav Kawm Ntawv 2/3 xav tau cov txheej txheem vuam (Preheat, tom qab peb tua tshav kub) {}

Cov Chav Txheem Ua Haujlwm: Paub meej sa537m (metric) lossis sa537 (Imperial) raws li phiaj xwm.

Hloov chaw: Rau kev ua tau zoo dua, xav txog sa516 gr.70} lossis sa533 hom b.
