Taw Qhia Rau S355 H Ntu Beam

S - stands for structural steel

355 - stands rau yam tsawg kawg nkaus yield zog (txawm hais tias nws yuav txawv raws li thickness, xa mus rau seem hauv qab no kom paub meej ntxiv)

Nquag S355 yuav muaj qhov hloov pauv raws li qhov cuam tshuam lub zog ntawm qhov sib txawv ntawm qhov kub thiab txias, vim tias cov hlau ua nkig ntau dua thaum kub poob. Yog tias koj tus qauv yuav tsum tiv taus -20 degree, nws zoo dua thiab muaj kev nyab xeeb dua rau xaiv S355J2.

S355JR - tuaj yeem tiv taus lub zog ntawm 27J ntawm +20 degree

S355J0 - tuaj yeem tiv taus lub zog ntawm 27J ntawm 0 degree

S355J2 - tuaj yeem tiv taus lub zog ntawm 27J ntawm -20 degree

S355K2 - tuaj yeem tiv taus lub zog ntawm 27J ntawm -30℃(40J ntawm -20 degree)

S355 muaj npe raws li nws qhov tsawg kawg nkaus tawm lub zog ntawm 355 Mpa (N / mm2), Txawm li cas los xij lub zog tawm los txo qis thaum koj nce mus rau hauv thickness saum 16 hli rau cov khoom tiaj tus & hollow seem.

Ntawm no yog lub rooj qhia txog kev txo qis hauv kev tawm dag zog raws li thickness
Txog li 16 hli - 355 Mpa
16 mm < t Tsawg dua lossis sib npaug li 40 mm - 345 Mpa
40 mm < t Tsawg dua lossis sib npaug li 63 mm - 335 Mpa
63 mm < t Tsawg dua lossis sib npaug li 80 mm - 325 Mpa
80 mm < t Tsawg dua lossis sib npaug li 100 mm - 315 Mpa
100 mm < t Tsawg dua lossis sib npaug li 150 mm - 295 Mpa

S355 Tensile zog

S355 qhov kawg tensile lub zog ntau kuj txawv raws li thickness.
Txog li 3 hli - 510 Mpa rau 680 Mpa
3 hli 100 mm < t Tsawg dua lossis sib npaug li 150 mm - 450 Mpa rau 600 Mpa
