S355J2G1W Birta

S355J2G1W saxan bir ah, EN 10155 S355J2G1W saxan bir ah, oo hoos timaada heerka EN 10155, waxaan u tixgelin karnaa S355 J2G1W saxan bir ah sida Steel Resistant to Atmospherical Corrosion oo leh qalab farsamo oo la mid ah S355J2G2. Marka lagu daro Cr, Cu iyo Ni, waxay samaysay lakabyo oksaydh ah oo si adag ugu dheggan dusha shaqada. Lakabka oksaydhisku wuxuu ka hortagayaa daxalka kale ee birta.

Tilmaamaha:
Dhumucda: 3mm--150mm
Ballaca: 30mm--4000mm
Dhererka: 1000mm--12000mm
Heerka: ASTM EN10025 JIS GB

S355J2G1W steel waa bir cimilo dhismeed, sidoo kale loo yaqaan birta u adkaysata daxalka atmospheric. Halabuurka kiimikada ee birta S355J2G1W waxay kordhin kartaa iska caabinta daxalka atmospheric, tani waa sababta oo ah waxay sameysaa lakab ilaalin dusha sare ee birta S355J2G1W iyadoo ay saameyn ku leedahay iska caabinta cimilada, adeegga birta ee S355J2G1W birta cimilada waa sida soo socota: goynta, rinjiyeynta, rasaas lagu qarxiyay. S355J2G1W xaaladaha gaarsiinta birta: giringiriyey kulul, qabow duuban, caadiga ah, demayn, xanaaqsan, habka xakamaynta thermomechanical (TMCP), technology remelting electroslag, imtixaanka HIC. Dhumucda saxanka birta: 2-460mm, ballac saxan bir ah: 1500-3200mm, dhererka: 6000-12000mm.
