ASTM A36 Carbon Steel Phaj Steel Sheet yog dav siv hauv kev tsim kho thiab kev lag luam thoob ntiaj teb. Tsim los ntawm ASTM International, cov hlau me me no yog tus cwj pwm los ntawm nws qhov sib npaug zoo ntawm lub zog, kev tsim, thiab tus nqi- ua tau zoo. Raws li qhov kub- dov qis- carbon steel, ASTM A36 ua cov khoom siv hauv paus rau ntau yam ntawm cov qauv siv, xws li cov tsev lag luam thiab cov txuas hniav mus rau kev siv tshuab thiab khoom siv ua liaj ua teb . Nws cov koob meej yog los ntawm nws cov khoom siv kho tshuab txhim khu kev qha, yooj yim ntawm fabrication, thiab tag nrho recyclability, ua rau nws muaj kev xaiv ruaj khov rau niaj hnub engineering tej yaam num.
Tshuaj muaj pes tsawg leeg
Cov tshuaj pleev ib ce ntawm ASTM A36 Carbon Steel Phaj txhais nws cov kev faib tawm raws li qis -carbon (mild) steel. Cov txheej txheem muaj xws li:
Cov pa roj carbon (C): 0.25%
Manganese (Mn): 1.20%
Silicon (Si): 0.40%
Phosphorus (P):0.03% (max)
Sulfur (S):0.03% (max)
Copper (Cu): 0.20%
Qhov kev sib xyaw tshwj xeeb no tso cai rau lub zog zoo ua ke nrog kev tsim kho, kom ntseeg tau tias cov hlau tuaj yeem ruaj ntseg nrog kev ceev faj tsawg.

Lus Cim: Cov khoom siv tshuab yuav txawv me ntsis raws li cov tuab thiab kev kho cua sov.
Cov yam ntxwv thiab qhov zoo
1. Superior Weldability thiab Fabrication
ASTM A36 Carbon Steel Phaj nthuav tawm cov khoom tshwj xeeb vuam, tso cai rau nws tuaj yeem koom nrog siv cov txheej txheem vuam nrog siab - cov txiaj ntsig zoo . Cov khoom siv kuj tsim nyog rau ntau yam kev ua haujlwm, suav nrog kev xuas nrig ntaus, sib tsoo, drilling, tapping, thiab nplaim taws txiav. Nrog rau tus nqi machinability ntawm kwv yees li 72% thiab qhov nruab nrab qhov chaw txiav pub ntawm 120 ko taw ib feeb, nws muaj peev xwm ua tau zoo rau cov tuam txhab.
2. Mechanical Strength thiab Ductility
Cov qib steel no muab cov qauv kev ua haujlwm ruaj khov thaum tswj kom txaus ductility. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 36 ksi (250 MPa) thiab lub zog tensile xws li 58 txog 80 ksi (400-550 MPa). Cov khoom elongation yog qhov tseem ceeb, nrog tsawg kawg yog 20% hauv 8 ntiv tes thiab 23% hauv 2 ntiv tes rau daim hlau thiab tuav. Qhov ductility no ua kom ntseeg tau tias cov qauv tuaj yeem deform tsis tu ncua nyob rau hauv kev ntxhov siab dhau ntawm qhov taw tes tawm, muab lub sijhawm ceeb toom tseem ceeb ua ntej muaj peev xwm tawg thiab txhim kho kev nyab xeeb hauv cov tsev thiab txuas hniav.
3. Tus nqi -Kev ua tau zoo thiab kev ruaj ntseg
Raws li cov pa roj carbon steel phaj, ASTM A36 tsis yog cov khoom kim heev, tab sis nws muab kev ua haujlwm siab muaj peev xwm ua tau ntau yam kev ua haujlwm siab. Nws yog recyclable tag nrho; cov khoom qub tuaj yeem xa rov qab mus rau qhov cub kom tsim cov hlau tshiab, txhawb kev lag luam kev lag luam hauv kev tsim kho
Cov txheej txheem kho cua sov
Thaum ASTM A36 feem ntau yog siv nyob rau hauv raws li -rolled mob, nws muaj peev xwm ua tau ntau yam kev kho cua sov kom hloov los yog txhim kho nws cov khoom siv kho tshuab:
Normalization:Ua ntawm 899℃rau 954℃(1650℃F txog 1750℃F), feem ntau yog kev kho mob zaum kawg tom qab tsim khoom.
Annealing:Ua ntawm 843℃rau 871℃(1550℃F txog 1600℃F) kom muag cov khoom thiab txo cov kev ntxhov siab sab hauv.
Stress Relieving:Siv ntawm 677℃rau 927℃(1250℃F txog 1700℃F).
Carburizing:Ua tiav ntawm 899℃rau 927℃(1650℃F txog 1700℃F) kom nce qhov tawv tawv.
Hardening:Ua tiav ntawm 788℃txog 816℃(1450℃F txog 1500℃F) thaum muaj zog thiab lub zog ntau dua rau kev tsim qauv
