S275JR pā kila

EN 10025 S275 kila (S275JR, S275J0 & S275J2)
ʻO EN 10025 S275 Steel kahi papa kila non-alloy, e like me EN10025, ʻo S275 ka mea hao māmā i hoʻokaʻawale ʻia i S275JR (1.0044), S275J0 (1.0143) a me S275J2 (1.0145). ʻOi aku ka maikaʻi o kekahi mau waiwai o S275 kila māmā ma mua o S235, a haʻahaʻa ma mua o S355.
ʻO ka inoa kahiko o S275 ʻo St44 e like me ka maʻamau o Kelemania, ʻo ke ʻano o ka pae kiʻekiʻe ma mua penei:
EN10025 S275JR (1.0044) – St44-2 ma DIN 17100
S275JO (1.0143) – St44-3U ma DIN17100
S275J2 (1.0145) – S275J2G4 ma EN 10025: 1993
EN10025 S275JR Manaʻo (Kauoha)
Hōʻike nā papa inoa ma lalo nei i ka manaʻo o EN10025 S275JR
ʻO "S" no ke kila hana;
ʻO "275" e pili ana i ka ikaika haʻahaʻa haʻahaʻa he 275 MPa i hoʻāʻo ʻia me ka mānoanoa kila ≤ 16mm.
"JR" 'o ia ho'i, 'o ka ha'aha'a ha'aha'a ha'aha'a ha'aha'a charpy ma ka lumi wela he 27J.
"J0" e pili ana i ka li'ili'i loa o ka hopena charpy ma 0 °C he 27J.
“J2” ʻo ia ka liʻiliʻi loa o ka hopena ma -20 °C he 27J.
S275 Pepa ʻIkepili a me nā kikoʻī
ʻO EN 10025 S275 mau waiwai kila, haku mele a me nā mea like i loaʻa i ka datasheet aʻe. ʻO ka pepa ʻikepili āpau o DIN EN 10025-2 ka like me BS EN 10025-2 a me nā mokuʻāina lālā ʻē aʻe o EU.

ʻO ka S275JR PLATE kahi pā kila i hana ʻia mai ke kila māmā a i ʻole ke kila kalapona. Hoʻohana nui ʻia kēia mau papa no ka hale kūkulu hale, hana ʻana i ka mea kanu, hale mīkini, a me ka mining. Hana ʻia kēia mau papa i ka alloy S275JR a he mea maʻalahi loa i ke ʻano.

Hoʻohui Kimia
ʻIke ʻikepili 1, EN10025 S275J0, S275J2 a me S275JR haku mele kemika ma muli o ka nānā ʻana o ka ladle i hāʻawi ʻia ma ka papa aʻe.

S275 na waiwai kila
Na Waiwai Kino
S275 kila māmā mānoanoa: 7.85 g/cm3
Ka helu hehee: 1420-1460 °C (2590-2660 °F)
Na Waiwai Mechanical
Hāʻawi ʻia nā waiwai mechanical steel S275 e like me ka ikaika hāʻawi, ka ikaika tensile, elongation a me ka hopena hopena i ka datasheet ma lalo.
