Hoʻomaka i ka 1.2379 Mea kila

1.2379 kila kila, i ʻike ʻia ma ke ao holoʻokoʻa ʻo D2 kila, he kalapona kiʻekiʻe, kiʻekiʻe chromium mea paahana hana anuanu i kaulana no kona kūpaʻa ʻokoʻa, ka ikaika compressive kiʻekiʻe, a me ke kūpaʻa maikaʻi loa. Hoʻohana nui ʻia ia i nā noi mea hana like ʻole me ka blanking dies, punches, shear blades, a me nā mea hana.

At SAKYSTEEL, He mea kūikawā mākou i ka hoʻolako ʻana i ka kila mea hana 1.2379 i ka pahu pōʻai, ka pā pālahalaha, a me nā poloka i hoʻopaʻa ʻia me ka maikaʻi a me ka hoʻokumu ʻana i nā kemika pololei. Ma kēia ʻatikala, hāʻawi mākou i kahi loiloi waiwai kemika a me ka mechanical o 1.2379 kila a e ʻimi i kāna mālama wela, nā noi, a me ka hoʻohālikelike ʻana me nā mea hao ʻē aʻe.

Hoʻohui Kimia o 1.2379 Mea kila (DIN Standard)

ʻO ka hui kemika ke kumu o nā waiwai mechanical a me ka mālama wela o ke kila mea hana. Wahi a DIN EN ISO 4957, ʻo ka mea hana kemika maʻamau o 1.2379 (D2) mea kila kila penei:

Nā mea koʻikoʻi kemika:

• Maʻiʻo Chromium Kiʻekiʻe (11-13%)hoʻonui i ka corrosion a me ka pale ʻana i ke kapa.
• Vanadium (0.8–1.2%)hoʻomaikaʻi i ka hoʻomaʻemaʻe palaoa a hoʻonui i ke ola mea hana.
• Kalapona (1.5%)hāʻawi i ka paʻakikī kiʻekiʻe ma hope o ka mālama wela.

Hoʻokumu kēia mau mea hoʻohui i kahi pūnaewele carbide ikaika i ka microstructure, e hoʻonui nui ana i ke ola o nā mea hana i nā wahi ʻaʻahu.

Na Pono Mechanical o 1.2379 Mea kila

Nā memo:

• Ma hope o ka hoʻomaʻamaʻa ʻana i ka wela a me ka hoʻomaʻamaʻa ʻana, hiki i ke kila ke kiʻekiʻe o ka paʻakikī a hiki i 62 HRC.
• Hoʻopaʻa i ka paʻakikī a hiki i 425 ° C, kūpono ia no nā noi kiʻekiʻe a me ka wikiwiki.

Hoʻomaʻamaʻa wela o 1.2379 / D2 Mea kila

ʻO ke kaʻina hana wela e hoʻoikaika nui i ka hana o D2 mea kila.

1. Hoʻopili

• Mahana:850 – 900°C
• Hoʻoluʻu:Hoʻolili ka umu ma ka max. 10 ° C / hola a 600 ° C, a laila hoʻomaha ka ea.
• Ke kumu:E ho'ēmi i ke kaumaha o loko a hoʻomākaukau no ka mīkini.

2. Ka paakiki

• Hoʻomaʻamaʻa mua:650 – 750°C
• Austenitizing:1000 – 1040°C
• Ke kinai ana:ʻO ka ea, kaʻaila a iʻole kaʻaila
• Nānā:E pale i ka wela nui e hiki ai ke ho'oha'aha'a i ka palaoa.

3. Hoohuoi

• Kaulana Mahana:150 – 550°C
• Nā pōʻaiapuni:ʻO ka maʻamau he 2 a i ʻole 3 mau pōʻaiapili
• Paʻa hope loa:58 - 62 HRC ma muli o ka mahana

ʻO ke kaʻina hana tempering e hōʻoia i ka paʻakikī a hōʻemi i ka brittleness ma hope o ke kinai ʻana.

Noi o 1.2379 mea hao kila

1.2379 mea kila kila i hoʻohana nui ʻia no:

• Make ka paʻa a me ke kuʻi
• Make ka ʻōwili kaula
• Make anu extrusion
• Nā mea hana hana a hoʻopaʻa
• ʻO nā ʻōpala palaki e koi ana i ke kūpaʻa ʻaʻahu kiʻekiʻe
• ʻO nā pahi ʻoihana a me nā pahi

Ma muli o kona kūpaʻa ʻaʻahu kiʻekiʻe a me ka paʻa ʻana o ka ʻaoʻao, ua kūpono ʻo 1.2379 no nā holo hana lōʻihi a me nā hana kiʻekiʻe.

Hoʻohālikelike me nā kila mea hana ʻē aʻe

SAKYSTEELManaʻo pinepine nā mea ʻenekinia i ka 1.2379 kahi e pono ai ka mea hana i ka paʻa o ka dimensional a me ke kūpaʻa ʻana i ka hana kiʻekiʻe.

Welding and Machineability

ʻAʻole ʻōlelo ʻia ʻo 1.2379 no ka hoʻopili ʻana ma muli o kona kiʻekiʻe o ke kalapona a me ka pilikia o ka haki ʻana. Inā ʻaʻole hiki ke pale ʻia ka wili:

• E hoʻohana i nā electrodes haʻahaʻa-hydrogen
• E puhi mua i ka 250–300°C
• Pono ka mālama ʻana i ka wela ma hope o ka weld

Mīkini:

ʻOi aku ka maʻalahi o ka mīkini 1.2379 ma kona kūlana annealed ma mua o ka paʻakikī. Manaʻo ʻia nā mea hana Carbide ma muli o ka loaʻa ʻana o nā carbide paʻakikī.

Nā Laʻau Ili

No ka hoʻonui ʻana i ka paʻakikī o ka ʻili a me ka pale ʻana i ka corrosion, hiki i ka 1.2379 kila kila ke hana:

• Nitriding
• Ka uhi PVD (TiN, CrN)
• Paʻa chrome paʻakikī

Hoʻonui kēia mau lāʻau lapaʻau i ke ola o ka mea hana, ʻoi aku hoʻi i nā noi kiʻekiʻe-friction.

Loaʻa nā ʻano a me nā nui

Hāʻawi mākou i nā lawelawe ʻokiʻoki a me ka wela e like me nā koi o ka papahana.

Nā Kūlana Kūlike o1.2379 Mea hao hao

Hāʻawi kēia kūlike i ka loaʻa honua o kēia mea me ka maikaʻi like.

Ka Manaʻo: No ke aha e koho ai i ka 1.2379 Mea kila?

ʻO 1.2379 / D2 mea hana kila he koho maikaʻi loa no nā noi mea hana kiʻekiʻe ma muli o kāna:

• Kūleʻa lole kiʻekiʻe
• ʻO ka paʻa ʻana o ka dimensional i ka wā mālama wela
• Paʻakiki maikaʻi loa
• Ka laulā o nā hoʻohana ʻoihana

No nā ʻoihana e koi ana i ka lōʻihi, ka pololei, a me nā mea hana pono, ʻo 1.2379 ka mea i paʻa i ke kila kila. No ka hana make a hana anu paha, hana mau ia ma lalo o ke kaomi.

At SAKYSTEEL, hōʻoia mākou i ke kila kila 1.2379 kiʻekiʻe me ka hoʻohui kemika pololei a me nā ʻae ʻana o ka nui. E hoʻokaʻaʻike mai iā mākou no ka loaʻa ʻana o ke kumukūʻai, ke kumu kūʻai, a me nā lawelawe mīkini maʻamau.

Nīnau nīnau e pili ana i 1.2379 mea kila

Q1: He aha ka paʻakikī kiʻekiʻe o 1.2379 ma hope o ka mālama wela?
A: A hiki i ka 62 HRC ma muli o ke kaʻina hana hoʻopau a me ka hana ʻana.

Q2: Hiki iā 1.2379 ke hoʻohana i nā kūlana hana wela?
A: ʻAʻole, ua hoʻolālā ʻia no nā noi hana anu.

Q3: ʻO D2 ke kila kila?
A: ʻAe, i kona kūlana paʻakikī, he ferromagnetic.

Q4: He aha nā mea ʻokoʻa maʻamau i ka 1.2379?
A: Hoʻohana pinepine ʻia nā mea kila A2 a me M2 ma muli o ka paʻakikī a i ʻole ka wela wela e pono ai.
