Q235 A36 Lub kaum ntse ntse Channel

Taw qhia rau ASTM 36

1, ASTM 36 yog American standard carbon structural phaj, kev ua raws li tus qauv ASTM A36/A36M-03a, tus qauv no muaj feem xyuam rau riveted, bolted thiab welded lug rau choj thiab vaj tse, raws li zoo raws li lub hom phiaj dav dav structural steel zoo carbon steel seem, daim hlau thiab bar steel. Cov hlau siv hauv ASTM 36 yuav tsum raug tua hlau.

2, ASTM 36 yog sib npaug rau Suav qib Q235. Q235 zoo tib yam carbon structural steel tseem hu ua A3 steel. (Ordinary carbon structural steel - cov phaj dav dav yog ib yam khoom siv hlau).

Ii. Taw qhia rau Q235

1. Q hauv Q235 sawv cev rau qhov txwv tsis pub dhau ntawm cov khoom siv no, thiab 235 hauv qab yog hais txog tus nqi tawm los ntawm cov khoom siv no, uas yog kwv yees li 235MPa. Tus nqi tawm los txo qis nrog qhov nce ntawm cov thickness ntawm cov khoom (phaj thickness / txoj kab uas hla Tsawg dua los yog sib npaug rau 16mm, yield zog yog 235MPa; 16mm < Phaj thickness / txoj kab uas hla Tsawg dua los yog sib npaug rau 40mm, yield zog ntawm 225MPa; 40mm< Phaj thickness / txoj kab uas hla Tsawg dua los yog sib npaug li 60mm, yield zog ntawm 215MPa; 60mm < Phaj thickness/inch Tsawg tshaj los yog sib npaug rau 100mm, yield zog ntawm 205MPa; 100mm < Phaj thickness / txoj kab uas hla Tsawg dua los yog sib npaug rau 150mm, yield zog ntawm 195MPa; 150mm < Phaj thickness / txoj kab uas hla Tsawg dua los yog sib npaug rau 200mm, yield zog 185MPa). Vim muaj cov ntsiab lus ntawm cov pa roj carbon tsawg, kev ua haujlwm zoo, lub zog, plasticity thiab vuam cov khoom tau zoo sib xws, feem ntau siv dav.

2, tsim los ntawm Q + tus lej + cim qib zoo + deoxidation qauv cim. Nws tus naj npawb steel yog ua ntej nrog "Q", uas sawv cev rau qhov taw tes tawm ntawm cov hlau, ua raws li tus lej qhia qhov txiaj ntsig ntawm tus nqi hauv MPa. Piv txwv li, Q235 qhia tias carbon structural steel nrog ib tug yield stress (σs) ntawm 235 MPa.
