ASTM A36 S235jr S275jr A572 A572 Ss400 Mild Carbon Hlau Kub Rolled Sib npaug Sib Nqus Lub kaum sab xis Steel Bar

Peb muaj ntau yam ntawm cov kub dov me me carbon steel lub kaum ntse ntse, muaj nyob rau hauv sib npaug thiab tsis sib npaug L-zoo li tus configurations, encompasses hwm thoob ntiaj teb qib xws li ASTM A36, ASTM A572, European EN series S235jr / S275jr, thiab Japanese JIS Ss400. Kev tsim kho kom tau raws li cov qauv nruj hauv cheeb tsam thiab thoob ntiaj teb (ASTM, EN 10025-2, JIS G 3101), cov kaum sab xis no yog tsim los ntawm cov qib siab -cov pa roj carbon zoo nrog cov tshuaj muaj zog tswj cov tshuaj muaj pes tsawg leeg-ua kom zoo dua cov pa roj carbon tsawg, sib npaug manganese qib, thiab traceconsums, sulfur. Cov txheej txheem no tso cai rau cov khoom lag luam nrog cov khoom tshwj xeeb, kev ua haujlwm zoo, thiab kev ncaj ncees, ua rau lawv muaj ntau yam kev daws teeb meem rau ntau hom kev lag luam, kev lag luam, thiab kev tsim kho vaj tse.

Txhua qib nyob rau hauv lub lineup muab tailored mechanical kev ua tau zoo kom haum varied load - bearing yuav tsum. ASTM A36, lub ntiaj teb staple hauv me me carbon steel, boasts qhov tsawg kawg nkaus yield zog ntawm 250 MPa (36,000 psi) thiab tensile lub zog ntawm 400-550 MPa (58,000{14}}80,000 psi), nrog zoo heev ductility 0% weldability (yam tsawg kawg nkaus). ASTM A572, siab -lub zog qis- qib alloy, muaj peev xwm ua kom muaj zog ntxiv-Qib 50 (qhov txawv tshaj plaws) nta 345 MPa yam tsawg kawg nkaus lub zog thiab 448-586 MPa tensile zog. European S235jr (235 MPa yam tsawg kawg nkaus yield zog, 360-510 MPa tensile zog) thiab S275jr (275 MPa yam tsawg kawg nkaus yield zog, 410-560 MPa tensile zog) muab graded zog rau lub teeb rau nruab nrab-lub luag hauj lwm daim ntaub ntawv. Japanese Ss400 (235 MPa yam tsawg kawg nkaus lub zog, 400-510 MPa tensile lub zog) sib npaug lub zog thiab ua haujlwm tau zoo rau kev siv dav dav. Txhua qib ua tau zoo tshaj plaws weldability, sib xws nrog cov txheej txheem vuam (SMAW, GMAW, FCAW), ua kom yooj yim seamless on-site fabrication.

Cov txheej txheem kub rolling manufacturing txheej txheem (ua ntawm qhov kub siab tshaj 900 degree, tshaj cov hlau recrystallization point) yog qhov tseem ceeb rau kev ua tau zoo ntawm cov me me carbon steel kaum bars. Cov txheej txheem no ua kom zoo dua cov qauv ntawm cov nplej, ua kom muaj zog, ua rau muaj kev cuam tshuam, thiab tag nrho cov qauv kev ruaj ntseg- tseem ceeb rau cov khoom uas raug static, dynamic, lossis cyclic loads. Muaj nyob rau hauv ob qho tib si sib npaug thiab tsis sib npaug, lub kaum sab xis npog ntau qhov ntev: sib npaug-legged variants (xws li 40 × 40 × 3, 80 × 80 × 6, 100 × 100 × 8 mm) rau kev sib npaug ntawm cov khoom faib; tsis sib npaug-legged variants (piv txwv li, 50 × 32 × 4, 100 × 75 × 6, 125 × 80 × 8 mm) rau asymmetric load txhawb. Cov txheej txheem kub dov ua kom muaj qhov tseeb qhov tseeb, zoo ib yam ntawm cov ceg squareness, cov tuab tuab, thiab nruj tolerances. Lub ntuj nto tiav ua kom muaj kev sib raug zoo rau kev tiv thaiv kev kho mob (kub-dip galvanization, epoxy txheej, hmoov txheej), txhim kho corrosion kuj thiab ncua kev pab cuam lub neej nyob rau hauv ib puag ncig hnyav.

Ua tsaug rau lawv cov kev xaiv qib sib txawv, kev teeb tsa dual, thiab kev ua haujlwm txhim khu kev qha, cov kub dov me me carbon steel lub kaum sab xis yog dav siv thoob plaws ntau qhov kev siv. Lawv ua haujlwm tseem ceeb hauv kev lag luam hauv tsev framing, kev cob qhia kev lag luam, kev tsim vaj tsev nyob, kev txhawb nqa choj, kev tiv thaiv kab mob, kev cia racks, thiab cov cuab yeej siv tshuab. Cov qhab-nees muaj zog tso cai rau cov kws ua haujlwm ua kom zoo dua cov khoom siv: S235jr / Ss400 / ASTM A36 rau kev tsim kho dav dav; S275jr/ASTM A572 rau nruab nrab mus rau hnyav Cov txheej txheem kev ruaj ntseg zoo yog siv thoob plaws hauv kev tsim khoom, suav nrog kev tshuaj xyuas tshuaj lom neeg los ntawm kev kho qhov muag emission spectrometry, kev txheeb xyuas cov cuab yeej cuab tam (tensile, yield, elongation tests), kev tshuaj xyuas qhov ntev nrog cov cuab yeej precision, thiab kev kuaj xyuas qhov tsis xws luag. Cov kev ntsuas no ua kom muaj kev ua raws li cov qauv kev sib raug zoo thiab kev ua haujlwm zoo ib yam thoob plaws txhua pawg. Rau cov kws tshaj lij nrhiav kev ua haujlwm siab -zoo, ntau- tus qauv me me carbon steel lub kaum ntse ntse nrog ntau yam kev teeb tsa, peb cov khoom lag luam muaj kev hloov pauv tsis sib xws thiab kev ntseeg tau.
