P355N ibyuma

Icyuma cya P335N cyumuvuduko wicyuma cyari gifite byibuze umusaruro wa 355 Mpa kubwubugari buri munsi ya 16mm. Ibyuma bya Gnee birashobora gutanga uburebure bwa plaque ya P355N hagati ya 6mm-300mm kugirango byemeze umutungo wibyuma mubigize imiti nubukanishi. Mugihe cyo gutanga toni 1000 gutumiza p355n ibyuma, igihe rusange cyo kuzunguruka kizaba muminsi 30.

P335N Ibiranga imiti:

Icyiciro	C%	Mn%	S%	N%	Cu%	Nb%	Ti%	Si%	P%	AL%	Cr%	Mo%	Ni%	Vi%
P 355 N.	0.10-0.22	0.10-1.70	0.015	0.012	0.30	0.020	0.03	0.60	0.025	0.020	0.30	0.08	0.30	0.02

EN 10028-3 P 355 N ibyuma bikoreshwa kwisi yose nabahimbye ubwato bwumuvuduko wogosha, amashyanyarazi yinganda hamwe nabahindura abahindura ubushyuhe kandi byashizweho kugirango bikore neza muri serivisi yubushyuhe bwo hejuru.

P335N Ibikoresho bya mashini:
