SPA-H na bakal

JIS G3125 SPA-H Corten steel,SPA-H steel plate/Sheet. SPA-H mababang haluang metal mataas na lakas atmospheric corrosion lumalaban bakal.
Mga pangunahing salita:SPA-H, JIS G3125 SPA-H hot rolled steel, JIS G3125 SPA-H steel plate/sheet/bar/section steel. JIS G3125 SPA-H Corten steel, SPA-H Weathering steel, SPA-H Weathering resistant steel, SPA-H atmosphere na lumalaban sa corrosion steel.
JIS G3125 SPA-H Corten steel malawakang ginagamit sa air preheater, economizer, railway carriage, container production, bridge building , construction at iba pa.

SPA-H Weathering steel kemikal na komposisyon
