Cov ntsiab lus tseem ceeb los txheeb xyuas hauv S550GD (1.0531)
Thaum txheeb xyuas S550GD (1.0531) muaj pes tsawg leeg, tsom rau cov ntsiab lus tseem ceeb no:
- Manganese (Mn): Xyuas kom nws nyob nruab nrab ntawm 1.00-1.60% rau kev pom lub zog. Tsawg heev txo lub zog; siab dhau cuam tshuam rau weldability.
- Cov pa roj carbon (C): Yuav tsum tsis pub tshaj 0.12% kom tswj tau formability thiab weldability.
- Phosphorus (P): Max 0.030% txhawm rau tiv thaiv qhov txias txias, tshwj xeeb tshaj yog nyob rau hauv qis - qhov kub thiab txias.
- Sulfur (S): Max 0.025% kom tsis txhob kub tawg thaum tsim.
- Aluminium (Al): Yam tsawg kawg nkaus 0.015% los kho cov qauv nplej thiab txhim kho toughness.
