Qhov sib txawv ntawm S235JR thiab S235J2 steel phaj

Jan 07, 2026 Tso lus

S235JR thiab S235J2 yog ob qho tib si tsis yog- alloy cov qauv hlau nrog qhov tsawg kawg nkaus tawm lub zog ntawm 235 MPa, tab sis lawv txawv ntawm lawv cov kev xav tau ntawm lub zog, nrog S235J2 (cov ntaub ntawv tus naj npawb 1.0117) muab qhov zoo dua qis dua - qhov kub thiab txias ua tau zoo dua li S2300JS3P (1. sulfur (S) cov ntsiab lus, thaum S235JR qhia txog qhov siab tshaj plaws Nitrogen (N) cov ntsiab lus, ua J2 feem ntau zoo tshaj rau cov ntawv siv txias dua txawm tias cov khoom zoo sib xws.

Qhov txawv tseem ceeb

Impact Testing Temperature: Tsab ntawv tom qab qhia txog lub zog nqus qhov ntsuas kub:

JR: Chav ntsuas kub (20 degree).

J2: Tsawg kub (feem ntau -20 degree).

Tshuaj muaj pes tsawg leeg: S235J2 muaj kev txwv nruj dua rau cov impurities, txhim kho toughness.

S235JR: Max P (0.035%), S (0.035%), N (0.012%).

S235J2: Max P (0.025%), S (0.025%), N (tsis muaj spec).

Mechanical Properties: Yield zog (235 MPa min) thiab lub zog tensile (360-510 MPa rau cov tuab tuab) feem ntau zoo ib yam, tab sis elongation yuav txawv me ntsis, nrog J2 feem ntau muaj qhov tsawg kawg nkaus elongation.
