Raws li EN 1.8967S355K2W) Weathering Steel. TS EN 1.8967 Cov hlau yog cov hlau alloy uas tsim los rau hauv cov khoom siv wrought.
S355K2W yog qhov nruab nrab tensile, qis carbon manganese weathering hlau uas yog yooj yim weldable thiab muaj kev cuam tshuam zoo (tseem nyob rau hauv qis-zero kub).
Tshooj S355K2W / 1.8967, siv rau hauv Hlau Structures thiab Composite Metaland Concrete Structures.
S355K2W, S355K2, S355JR European Standard Qauv Steel Phaj
Cov qib no yog ib feem ntawm EN10025-5 cov ntaub ntawv txheem. S355K2W yog cov huab cua-resistant steel phaj, thaum S355K2 thiab S355JR yog cov hlau tsis tshua muaj zog. Lub npe "JR" qhia txog 20 degree qhov kev ntsuam xyuas, "K2" qhia txog qhov kev ntsuas -20 degree, thiab "W" sawv cev rau huab cua-resistant, txhais tau tias nws tiv taus atmospheric corrosion.
