Pākē kūʻai nui ʻia ʻo Carbon a i ʻole Alloy Steel Pipe ma GB/T 8162-2008 20 # 45 # 45mn2 Q355b Q355D 27simn
ʻO ka wehewehe pōkole:
Hoʻohana nui ʻia nā paipu kila 27SiMn i nā ʻoihana kaʻa, ka aila, kemika a me nā ʻoihana moku.27SiMn kila paipu mea maʻamau a me ka huhū, a uhiʻia me ka phosphate i loko a me waho.Hoʻohana nui ʻia kēia paipu kila i ka mokuʻāina i hoʻopaʻa ʻia a hoʻonāukiuki ʻia e hana i nā ʻāpana stamping wela (nā ʻāpana hydraulic) e koi ana i ka paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana, a me nā ʻāpana stamping wela e koi ana i ka paʻakikī kiʻekiʻe a me ke kūpaʻa.
27SiMn seamless kila paipu i kiʻekiʻe hardenability, ke koʻikoʻi hardenability anawaena i loko o ka wai mea 8 ~ 22mm, maikai machinability, medium anu deformation plasticity a weldability;Eia kekahi, ʻaʻole i hoʻemi nui ʻia ka paʻakikī o ka paipu kila i ka wā o ka mālama ʻana i ka wela, akā he kiʻekiʻe kiʻekiʻe ka ikaika a me ke kūpaʻa ʻana, ʻoi aku ka nui o ka hoʻopau ʻana i ka wai.
Hoʻohiki kā mākou paʻa i nā poʻe āpau mai nā waiwai papa mua me ka ʻoihana ma hope o ke kūʻai ʻana.Hoʻokipa maikaʻi mākou i kā mākou mau mea kūʻai maʻamau a hou e hui pū me mākou no ka Chinese wholesale Seamless Carbon a i ʻole Alloy Steel Pipe ma GB / T 8162-2008 20 # 45 # 45mn2 Q355b Q355D 27simn, Hoʻohanohano mākou i kā mākou kumu kumu o ka Honesty i ka ʻoihana, ka mea nui i ka hui a e hana i kā mākou mea maikaʻi loa e hoʻolako i kā mākou mea kūʻai aku i nā waiwai kiʻekiʻe a me ka mea hoʻolako maikaʻi.
