ASTM A709 GR.50W pā kila

ʻO ka ikaika kiʻekiʻe haʻahaʻa haʻahaʻa haʻahaʻa kila pā ASTM A709GR.50W i kapa ʻia hoʻi e like me ka pā kila A709 Grade 50W i ka pono o kāna waiwai i ka pale ʻana i ka corrosion. Wahi a nā ʻano mea kemika nui ʻē aʻe, ua māhele ʻia ʻo A709 Grade 50W e like me A709Gr50w type A, A709Gr50w type B, A709Gr50w type C. ʻO kēia mau māka kila ʻekolu e like me ka kikoʻī ASTM A 588/A 588M A588 Grade B, a me A588 Grade C. Low alloy steel plate A709 Grade 50W no hoi ka palena palena iki o ka ikaika ma 345 Mpa me A709 Grade 50 pa kila.
A709 Gr.50W weathering kila papa, i kaulana no kona waiwai i ka lewa corrosion kū'ē. Hoʻohana nui ʻia nā papa kila A709 Grade 50W i nā mīkini hana, nā mīkini mining, nā kaʻa, nā alahaka, nā moku kaomi i nā hale kūkulu hale etc.,

Koi ʻenehana a me nā lawelawe hou aku:

• ʻO ka hoʻāʻo kiʻekiʻe
• Haʻahaʻa wela hopena hoao
• ʻO ka hoʻomaʻamaʻa ʻana i ka wela ma hope o ka welded (PWHT)
• Hāʻawi ʻia ka palapala hōʻike hoʻāʻo ʻo Oginal Mill ma lalo o EN 10204 FORMAT 3.1/3.2
• Ke kuhikuhi ʻia ke kila cooper no A709 Gr36, ʻo ka ʻike Cu≥0.20%
• ʻO ka pana ʻana a me ka pena ʻana, ka ʻoki ʻana a me ka wili e like me nā koi o ka mea hoʻohana hope

No ka waiwai hou aku ma ka pā kila A709 Gr.50S, e ʻoluʻolu e nānā iā lākou ma ka hahai ʻana;
