Qhov txawv ntawm A 516 70 thiab A 572 50 yog dab tsi?

Tsis meej pem ntawm ASTM A516 Qib 70 thiab ASTM A572 Qib 50 steel? Qhov no hauv - phau ntawv qhia tob piav qhia qhov sib txawv tseem ceeb hauv chemistry, mechanical properties, and applications. Koj tuaj yeem kawm paub xaiv cov khoom tsim nyog rau koj qhov project kom muaj kev nyab xeeb, ua raws, thiab tus nqi - ua tau zoo.

Raws li engineers, designers, thiab procurement specialists, xaiv cov khoom tsim nyog yog ib qho kev txiav txim siab tseem ceeb tshaj plaws uas peb ua. Qhov kev xaiv cuam tshuam ncaj qha rau kev nyab xeeb, kev ua haujlwm, thiab kev siv nyiaj txiag. Ob qhov feem ntau teev cov pa roj carbon steel phaj yog ASTM A516 Qib 70 thiab ASTM A572 Qib 50.

Ntawm ib sab, lawv cov khoom siv tshuab tuaj yeem zoo sib xws, tab sis lawv tsis hloov pauv. Kev siv qhov tsis ncaj ncees lawm tuaj yeem ua rau muaj kev puas tsuaj loj lossis tsis yog - ua raws li cov cai. Yog li, qhov txawv ntawm A516 Qib 70 thiab A572 Qib 50 yog dab tsi?

Kab lus no yuav rhuav tshem qhov sib txawv tseem ceeb los pab koj txiav txim siab paub txog koj qhov project tom ntej.

Qhov no yog qhov sib txawv tseem ceeb tshaj plaws thiab qhov pib ntawm kev xaiv.

ASTM A516 Qib 70: Cov hlau no yog tswj hwm los ntawm ASME Boiler thiab Pressure Vessel Code (BPVC). Nws qhov kev thov tseem ceeb yog hauv kev tsim cov hlab ntsha siab. Lub "70" qhia txog qhov tsawg kawg nkaus tensile lub zog ntawm 70 ksi. Nws yog tsim tshwj xeeb los tiv thaiv lub siab sab hauv thiab muaj qhov zoo tshaj plaws toughness, tshwj xeeb tshaj yog nyob rau nruab nrab thiab qis kub. Koj yuav pom nws nyob rau hauv welded boilers, cia tso tsheb hlau luam, thiab lwm yam siab- muaj cov qauv.

ASTM A572 Qib 50: Qhov no yog siab -lub zog, qis- alloy (HSLA) cov qauv hlau. Qhov "50" qhia txog qhov tsawg kawg nkaus tawm lub zog ntawm 50 ksi. Nws yog tswj hwm los ntawm cov qauv zoo li AISC rau kev siv cov qauv. Nws qhov kev siv tseem ceeb yog nyob rau hauv cov choj, cov tsev, thiab lwm yam kev ua haujlwm uas muaj zog heev - rau - qhov hnyav piv yog qhov tseem ceeb. Nws muaj qhov zoo weldability thiab muaj zog ntau dua li cov qauv carbon steel zoo li A36.

Qhov sib txawv ntawm daim ntawv thov stems los ntawm lawv cov tshuaj pleev ib ce.

ua 516g70yog carbon{0}}silicon steel. Cov chemistry yog ua tib zoo tswj, nrog rau kev txwv ntawm cov ntsiab lus xws li manganese, phosphorus, thiab sulfur los xyuas kom meej weldability thiab notch toughness. Nws kuj tseem yuav muaj ntxiv Charpy V-Kev ntsuas qhov ntsuas qhov ntsuas qhov ntsuas (piv txwv li, A516 Gr 70N).

A572 gr 50yog High-Strength Low-Alloy (HSLA) Columbium-Vanadium steel. Nws muaj me me, txhob txwm ntxiv ntawm alloying ntsiab xws li columbium (niobium) thiab / los yog vanadium. Cov ntsiab lus no muab kev txhawb zog los ntawm kev ua kom zoo ntawm cov nplej thiab nag lossis daus hardening, tso cai rau nws ua kom muaj zog dua nrog qhov hnyav dua.

Thaum ob qho tib si muaj zog, lawv lub zog profiles tau txhais txawv.

Daim ntawv ceeb toom tias A572 Gr 50 muaj lub zog tawm los ntau dua li A516 Gr 70, uas feem ntau yog qhov tseem ceeb hauv kev tsim qauv los tiv thaiv kev deformation mus tas li.

Feem ntau, A572 Qib 50 yog tus nqi ntau dua - ua haujlwm tau zoo dua A516 Qib 70. Cov txheej txheem tsim khoom nruj, cov kev xav tau ntawm kev sim (tshwj xeeb tshaj yog cuam tshuam), thiab daim ntawv pov thawj xav tau rau kev siv lub nkoj siab ua rau A516 yog cov khoom zoo. Rau cov ntawv uas tsis yog -siab, siv A516 qhov twg A572 yuav txaus yog qhov tsis tsim nyog.

Kev xaiv txoj cai yog ncaj nraim yog tias koj ua raws li qhov kev xav no:

Xaiv ASTM A516 Qib 70 yog: Koj cov khoom siv yog lub nkoj siab, boiler, lossis ib qho khoom siv tswj hwm los ntawm ASME BPVC uas yuav tsum muaj lub siab sab hauv. Kev nyab xeeb thiab kev sib tw toughness yog koj qhov tseem ceeb tshaj plaws.

Xaiv ASTM A572 Qib 50 yog tias: Koj qhov project yog tus choj, lub tsev, lossis cov qauv txheej txheem uas lub hom phiaj tseem ceeb yog los txhawb nqa cov khoom siv siab - lub zog, lub teeb yuag. Tus nqi-kev ua tau zoo rau cov qauv siv yog qhov tseem ceeb.

Hu rau tam sim no

Nco ntsoov sab laj tus qauv tsim qauv (ASME rau cov cuab yeej siv siab, AISC rau cov qauv) thiab koom nrog cov ntaub ntawv pov thawj engineer thaum tsis ntseeg. Kev siv cov ntaub ntawv raug tsis yog ib qho kev pom zoo xwb - nws yog qhov yuav tsum tau muaj kev nyab xeeb thiab kev ntseeg tau.

ASTM A572 GR 50 tus qauv yog dab tsi?

ASTM A572 GR 50 yog asiab zog low alloy steel. Qib 50 yog qhov nyuaj rau kev tsim vim nws muaj cov ntsiab lus alloying ntau dua li cov hlau dawb tab sis muaj zog ntau dua rau ib chav tsev ntawm qhov hnyav. Ua tsaug rau nws lub zog siab ASTM A572 Qib 50 Phaj yuav tsum muaj cov khoom siv tsawg dua kom ua tau raws li qhov yuav tsum tau muaj zog dua li cov pa roj carbon monoxide.
