S275N pā kila
Hoʻokomo i ka maʻamau: EN 10025-3
E kūʻai aku i ka papa kila: S275N,S355N,S420N,S460N,S275NL,S355NL,S420NL,S460NL pā kila.

S275N/S275NL pā kila

S275N/S275NL kila mea he wela olokaa structural steels, i olokaa mau kūlana no ka normalized a maʻamau olokaʻa i weldable palaoa maikai structural kila kila.

ʻO ka pā kila S275N me nā waiwai liʻiliʻi o ka ikehu hopena ma nā mahana ʻaʻole i emi iho ma lalo o -20 degere.

ʻO ka pā kila S275NL me nā waiwai liʻiliʻi o ka ikehu hopena ma nā mahana ʻaʻole i emi iho ma lalo o -50 degere.

Hiki i ke kila Gnee ke hāʻawi pololei i nā pā S275N/S275NL mai kā mākou wili i ke kumukūʻai hoʻokūkū mai ka ʻoihana kūʻai. Loaʻa i kēlā me kēia pā ka Mill Certificate Test EN 10204 3.1 a i ʻole 3.2.

E pili ana i ka S275N/S275NL ka ʻike kikoʻī, e ʻoluʻolu e nānā i ka lā ʻenehana ma hope.

ʻO ka Chemical ka hoʻohui kiʻekiʻe o ka nānā ʻana i nā huahana:
