Q390D Tsawg- alloy Siab- lub zog steel phaj
Q390D steel phaj yog cov hlau tsis tshua muaj siab lub zog steel phaj, Q390D tsis yog tsuas yog lub zog siab steel, nws kuj yog cov hlau tsis tshua muaj steel.Q390D cov hlau tsis tshua muaj hlau tsis muaj zog muaj zog yield, siab toughness thiab tsis tshua muaj kev hloov kub; zoo dua txias forming zog thiab vuam zog; zoo corrosion kuj thiab qee qhov hnav tsis kam.
