ASME SA387 GR.22 CL2 Pahu hao a me ka ipu hao paʻi

SA 387 GR.22 CL.2 PLATE loaʻa ka chromium o 2.25% a me ka molybdenum o 1% a me ka hiki ke hana i nā mahana 600 Deg C a puni pono. Ke hana maikaʻi nei ka molybdenum a me nā pā kila chromium ma nā ʻano wela like ʻole e hāʻawi mau ana i ka hana maikaʻi loa. ʻO ka hoʻohui ʻana o ka molybdenum i ka SA 387 alloy e hoʻonui ana i ka ikaika tensile o nā papa i ka wela nui. Eia kekahi, hāʻawi ʻo ia i ka hiki ke kū i ka corrosion maikaʻi a me ka oxidation me ka hoʻonui ʻana i ka lattice strain. Hoʻopau maikaʻi kēia i ka mea corrosive mai ka hoʻoheheʻe ʻana i ka hao a hāʻawi i ka hiki ke pale wela maikaʻi a lilo i koho maikaʻi no ke kinoea a puni. Eia kekahi, loaʻa iā ia ka weldability maikaʻi. No laila, koi nui ʻia kēia papa ma ka honua.

Nā Kūlana Kūlana no ASME SA387 Alloy Steel Plate

ASME

• SA20/A20M: Nā koi maʻamau no nā pā ipu kaomi.
• SA370: Hōʻike hoʻāʻo no nā waiwai mechanical o ke kila
• SA435/A435M: No ka nānā ʻana i ka ultrasonic beam pololei o nā papa kila
• SA577/A577M: No ka hoʻokolokolo ʻana i ke kaola kani ultrasonic o nā papa kila
• SA578/A578M: ​​No ka nānā ʻana i ka UT beam pololei o nā papa kila i ʻōwili ʻia i nā noi kūikawā
• SA1017/A1017M: Hōʻikeʻike no nā pā pahu kaomi o ke kila kila, chromium-molybdenum-tungsten

• A5.28/A5.28M: No ke kinoea pale arc wiliwili
• A5.29/A5.29M: No ka hoʻoheheʻe ʻia ʻana o ka flux cored arc.

Hoʻomaʻamaʻa wela no SA387 Chrom Moly Alloy Steel Plate

E pepehi ʻia ʻo Chrome moly alloy steel plate ma lalo o ASME SA387 i ke kila, me ka thermally mālama ʻia e ka annealing, normarlizing a me ka hoʻoluhi ʻana. A i ʻole inā ʻae ʻia e ka mea kūʻai aku, e hoʻomaʻamaʻa wikiwiki ʻia mai ka wela austenitizing ma o ka puhi ʻana i ka ea a i ʻole ka hoʻopau ʻana i ka wai, a ukali ʻia e ka hoʻomaʻamaʻa ʻana, ʻo nā mahana wela haʻahaʻa loa e like me ka papa ma lalo:
