Q345r steel yog lub phaj tshwj xeeb rau cov hlab ntsha siab nrog cov txiaj ntsig lub zog ntawm 345MPA. Nws muaj cov khoom siv kho tshuab thiab cov txheej txheem kev ua tau zoo. Cov ntsiab lus phosphorus thiab cov tub ntxhais cov ntsiab lus qis dua qis dua qhov qis-alloy High-zog steel phaj Q345 (16mn) hlau. Ntxiv rau lub tensile muaj zog thiab elongation yuav tsum tau siab dua li cov ntawm Q345 (16mn) yog qhov yuav tsum tau ua kom zoo nkauj. Nws yog qhov dav tshaj plaws siv thiab feem ntau cov siv hlau siv rau cov nkoj siab hauv kuv lub tebchaws.
Q345R (R-HIC) Kuv yog hais txog THEAD Qib Q345R. Kev ntsuas corrosion yog hydrogen-inducts cracking (hic) thiab sulfide kev nyuaj siab corrosion (SSC). Qhov muaj pes tsawg leeg yuav tsum tau txheeb xyuas p tsawg dua lossis sib npaug rau {}}}}. {8}} 03; Cov khoom tiav tau txheeb xyuas p tsawg dua lossis sib npaug rau 0.015, s tsawg dua lossis sib npaug rau 0.004
Q345RHic yuav tsum muaj hic hydrogen-inducts tawg kuaj. Q345rr-hic yuav tsum muaj hic hydrogen-inducts nraws nraus kuaj thiab SSC hydrogen sulfide kev ntsuam xyuas. Q345RHIC thiab Q345RR-HIC kev ntsuas ib puag ncig: kev daws teeb meem HIC, kev ntsuas kub, kev ntsuas kub, me me tshuaj xyuas, kev soj ntsuam me me, cov khoom lag luam tiav tsom xam.
