P275N Paʻi Paʻi Paʻa Paʻa

EN10028 P275N pā kila/pepa, ma lalo o EN maʻamau, hiki iā mākou ke nānā i ka pā kila P275N/pepa no nā paila a me nā Paʻa Paʻa. ka pā kila a me ka pepa i hoʻohana nui ʻia no ke kūkulu ʻana i nā ipu kaomi a me nā paila a me nā paipu no ka wai wela.

Ma lalo o ka EN10028_3 maʻamau, ʻo ka pā kila P275N ma lalo o ka Normalized delivery condition when processing.These steel grade P275NH a me P275N i hoʻohana nui ʻia i loko o nā ipu kaomi a me nā paila ʻokoʻa mai nā papa kila carbon_manganese nona ke kūpaʻa kiʻekiʻe i ke kaomi ma nā mahana āpau ke hoʻohana ʻia.
