BV Qib A MARINE Steel Phaj

 

BV Qib A marine steel phaj yog hom hlau phaj ntawv pov thawj los ntawm Bureau Veritas (BV), lub npe nrov hauv kev lag luam hauv kev lag luam marine. Nov yog nws cov yam ntxwv tseem ceeb thiab cov ntaub ntawv tseem ceeb:

 

Tshuaj muaj pes tsawg leeg:

Cov pa roj carbon (C): Cov ntsiab lus siab tshaj plaws yog 0.21%.

Silicon (Si): Txog li 0.50%.

Manganese (Mn): Tsawg kawg yog 2.5 npaug ntawm cov ntsiab lus carbon.

Phosphorus (P): Tsis ntau tshaj 0.035%.

Sulfur (S): Tsis ntau tshaj 0.035%.

Mechanical zog:

Tawm lub zog: 34,100 psi (kwv yees 235 MPa).

Qhov kawg tensile zog: thaj tsam ntawm 58, 000 mus rau 75,500 psi (400 txog 520 MPa).

Elongation: Tsis pub tsawg dua 22% (rau qee qhov tuab tuab).

Kev cuam tshuam lub zog: Nws muaj qee qhov kev xav tau rau kev cuam tshuam lub zog ntawm 20 degrees Celsius, uas qhia tias nws muaj peev xwm tiv taus qhov kub thiab txias.
