B460NQR hlau

B460NQRis huab cua resistant steel tsim los ntawm alloying tooj liab, chromium thiab npib tsib xee.
B460NQRhas ntxiv phosphorous uas ua rau cov khoom siv zoo tshaj plaws rau kev siv roj flue thiab rau kev zoo nkauj facias.

Cov specifications:
Thickness: 3mm-150mm
Dav: 30mm-4000mm
Ntev: 1000mm-12000mm
Txuj: ASTM EN10025 JIS GB
