Cov Khoom Qhia Txog Khoom

Cov Cim Npe Khoom

Cov Khoom Siv Yeeb Nkab STPG 370 yog dab tsi?

STPG 370 yog qib yeeb nkab hlau uas muaj cov pa roj carbon tsawg uas tau teev tseg hauv tus qauv Nyiv Pooj JIS G 3454.

STPG 370 muaj lub zog tensile tsawg kawg nkaus ntawm 370 MPa thiab lub zog yield tsawg kawg nkaus ntawm 215 MPa.

STPG 370 tuaj yeem tsim ua cov kav hlau tsis muaj seamless lossis cov kav hlau welded siv cov txheej txheem hluav taws xob tsis kam vuam (ERW). Nws yog qhov tsim nyog rau kev siv hauv cov kav dej siab nrog qhov kub ua haujlwm txog li 350 ° C.

Tom ntej no, peb yuav los saib STPG 370 los ntawm cov txheej txheem tsim khoom, cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab, kev sim siab hydrostatic, kev sim tsis puas tsuaj, thiab kev txheej galvanized.

Ntxiv rau lub zog tensile, lub zog tensile, thiab elongation uas tau hais los saum toj no, kuj tseem muaj kev sim flattening thiab bendability.

Kev Ntsuas Kom Sib Nqus: Thaum qhov deb ntawm ob lub phaj ncav cuag qhov deb H uas tau teev tseg, yuav tsum tsis muaj qhov tsis zoo lossis tawg ntawm qhov chaw ntawm cov yeeb nkab hlau.

Kev khoov tau: Cov yeeb nkab yuav tsum tau khoov 90° ntawm lub vojvoog ntawm 6 npaug ntawm nws txoj kab uas hla sab nraud. Phab ntsa yeeb nkab yuav tsum tsis muaj qhov tsis zoo lossis tawg.
