atmospheric corrosion resiting structural steel phaj yog dav siv los tsim cov thawv ntim khoom thiab cov thawv tawm sab nraud, xws li Teem caij cov thawv ntim khoom pov tseg, Huab cua Shelters, Cov thawv ntim khoom, Cov thawv ntim khoom thiab lwm yam.
Cov specifications:
Thickness: 3mm-150mm
Dav: 30mm-4000mm
Ntev: 1000mm-12000mm
Txuj: ASTM EN10025 JIS GB
Siab tensile lub zog weathering steel phaj Q415NH nrog tensile lub zog nyob rau hauv 520-680 Mpa, sib npaug thickness, yield zog yuav tsum siab tshaj 415Mpa thaum bellows yog 16 hli. Raws li qhov sib txawv ntawm qhov kub thiab txias, Q415NH steel phaj tuaj yeem yog Q415NHA, Q415NHB, Q415NHC,
Q415NHD, Q415NHA. Q415NHA yuav tsum muaj qhov ntsuas kub ntawm qhov ntsuas kub ntawm qhov ntsuas kub qis dua 40 degrees Celsius, thiab Q415NHA tsis tas yuav muaj qhov cuam tshuam.
