FAQ
Puas yog St52 zoo ib yam li E355 thiab S355?
Yog - St52 nyob rau hauv kev rho tawm DIN 2391 thiab E355 raws li EN 10305-1:2016 yog tib cov hlau raws li cov khoom siv 1.0580. S355 yog tib yam chemistry hauv tsev neeg hlau (EN 10025-2). Cov hlau tsis hloov; tsuas yog tsev neeg tus qauv thiab cov xwm txheej xa tuaj ua. Ib txwm sau tus qauv nrog lub npe, vim tias tib qib lej muaj nyob hauv ntau dua ib tsev neeg.
Vim li cas kuv thiaj pom ob qho tib si 355 MPa thiab 450 MPa hais raws li cov txiaj ntsig ntawm St52?
355 MPa yog cov txiaj ntsig ntawm qhov kev ua haujlwm ib txwm muaj (+ N / NBK) thiab kuj yog S355 tus nqi qauv. Qhov kev ntxhov siab-relieved txias-txoj kev mob (+ SR/BKS) nce qhov tsawg kawg nkaus tawm los mus rau 450 MPa, thiab qhov txias - rub- mob hnyav (+ C / BK) lav lub zog tensile yam tsawg kawg nkaus 640 MPa tab sis tsis muaj cov txiaj ntsig tau teev tseg. Tus naj npawb koj tsim los yog nyob ntawm qhov kev xa khoom ntawm qhov kev txiav txim - lawv yog cov hlau qub, tsis yog ob qib sib txawv.
Puas yog lub bore ntawm St52 txias drawn tube tiav rau H8?
Tsis yog. Ib lub raj txias uas tsis muaj seamless tswj lub taub sab nraud thiab phab ntsa thickness rau h8–h11; lub bore yog raws li -kos puab nto ntawm Ra 0.8–1.6 µm, tsis tiav H8/H9 qhov. H8 yog qhov ua siab ntev ntawm lub honed lossis SRB lub tog raj kheej raj. Yog tias koj daim ntawv thov xav tau ib lub bore tiav, xaj peb ST52.3 honed raj lossis SRB raj qhov twg cov bore coj mus rau H8 / H9 ntawm Ra 0.2–0.4 µm.
Qhov txawv ntawm St52, St52.3 thiab St52.4 yog dab tsi?
St52 ib leeg yog DIN 2391 precision- raj qib (tam sim no EN 10305-1 E355, khoom tsis muaj. 1.0580). Lub ntsiab lus hloov cov qauv tsev neeg: St52.3 yog cov hmoov nplej zoo sib txawv siv rau hydraulic lub tog raj kheej raj, thaum St52.4 belongs rau DIN 1630 (cov raj seamless zoo tshwj xeeb) nrog cov khoom siv sib txawv (yield tsawg kawg yog 320 MPa, tensile 490-670 MPa). Lawv tsis tuaj yeem hloov pauv yam tsis tau kuaj xyuas tus qauv sau rau ntawm daim duab.
Dab tsi ASTM qib sib npaug rau St52?
Qhov ze tshaj plaws ASTM txoj kev muab khoom yog A519 qib 1026. Txawm li cas los xij, AISI 1026 muaj manganese siab tshaj plaws ntawm 0.90%, whereas St52/E355 tso cai rau 1.60% manganese, yog li 1026 yog ib lub raj - kev muab khoom, tsis yog qib equi. Tsis txhob kho lawv zoo ib yam chemistry ntawm daim ntawv pov thawj khoom.
Kuv puas tuaj yeem siv St52 txias rub raj ncaj qha raws li lub tog raj kheej hydraulic?
Tsuas yog tom qab lub bore tiav lawm. Lub raj xa dej txias St52 yog cov khoom lag luam niam rau lub tog raj kheej, tab sis nws raws li - kos bore tsis nruj txaus rau lub foob. Txhawm rau npaj - los - sib dhos chim, xaj peb ST52.3 honed raj lossis SRB raj qhov twg lub bore coj mus rau H8 / H9 ntawm Ra 0.2–0.4 µm.
Qhov kev xa khoom twg kuv yuav tsum tau qhia rau St52 precision raj?
Nws nyob ntawm kev ua haujlwm: +SR / BKS (yield 450 MPa) rau welded lossis kev ntxhov siab- qhov tseem ceeb; + N / NBK (yield 355 MPa, 22% elongation) rau hnyav machining lossis sib sau; + C / BK (Rm tsawg kawg yog 640 MPa) rau siab - lub zog machined Cheebtsam. Qhia lub cim thiab EN / DIN xwm txheej ntawm daim ntawv xaj kom lub zeb paub tias lub zog twg los ua pov thawj.
Cov tshuaj muaj pes tsawg leeg ntawm St52 / E355 yog dab tsi?
Raws li EN 10305-1: 2016 Table 2, E355 (St52, 1.0580) muaj cov pa roj carbon ntau tshaj 0.22%, silicon 0.55%, manganese 1.60%, phosphorus 0.025%, sulfur 0.025% 0.0% thiab 9% txhuas . siab kawg. Nws yog cov pa roj carbon monoxide -manganese steel, tsis yog cov hlau tsis tshua muaj hlau.
