SM400 steel phaj

Dec 04, 2025 Tso lus

SM400A, SM400B thiab SM400C steel daim hlau yog Japanese txheem dov steel rau vuam qauv, S sawv cev rau hlau, M sawv cev rau vuam, 400 kuj yog qhov qis qis tensile zog 400MPa, A yog cov hlau phaj qib, tsis muaj kev cuam tshuam, B yog cov hlau phaj qib, cuam tshuam ntawm 20℃steel phaj, C qib siab.

Txuj ci rau SM400A, SM400B thiab SM400C steel daim hlau: JIS G3106.

Melting tsom xam ntawm cov tshuaj muaj pes tsawg leeg ntawm SM400A, SM400B thiab SM400C steel daim hlau:
