Te Hanganga Matū o ngā Wāhanga Rino DIN EN 10305-2

Te hanganga matū noa o ngā rauemi DIN EN 10305-2:

Tau	C Max	Mn Max	Si Max	P Mōrahi	S Max
E155	0.17	1.20	0.35	0.025	0.025
E195	0.20	1.40	0.40	0.025	0.025
E235	0.22	1.60	0.55	0.025	0.025
E275	0.24	1.60	0.55	0.025	0.025
E355	0.22	1.60	0.55	0.025	0.025
E420	0.22	1.70	0.60	0.025	0.025
E460	0.22	1.70	0.60	0.025	0.025

Mā ēnei hanganga matū ka tino pai te kaha ki te whakarewa me te mahi ā-ringa mō ngā ngongo whakarewa kua kumea matao.

 

Ngā Āhuatanga Hangarau o ngā Ngongo Whakarewa Matao DIN EN 10305-2

He rerekē ngā āhuatanga ā-pūkaha i runga i te kounga o te maitai.

Tau	Te Kaha o te Hua	Kaha Kume	Te whakaroa
E155	≥155 MPa	290-430 MPa	≥28%
E195	≥195 MPa	320-460 MPa	≥25%
E235	≥235 MPa	340-480 MPa	≥25%
E275	≥275 MPa	410-560 MPa	≥21%
E355	≥355 MPa	490-630 MPa	≥20%
E420	≥420 MPa	520-680 MPa	≥19%
E460	≥460 MPa	550-720 MPa	≥17%

Ko ngā momo teitei ake pēnei i te E355, E420, me te E460 e whakamahia whānuitia ana mō te hanga rango karu tirotiro me te rango waipēhi.

 

Nga Tikanga Tukunga I raro i te DIN EN 10305-2

Kei roto i te DIN EN 10305-2 ētahi tikanga tuku:

+SR Whakamamaehia te ahotea i te makariri i tangohia
+N Kua Whakapūmautia
+He mea whakawerawera
+CR Kua tāia mātao

I roto i ēnei,+SRte āhuatanga e whakamahia whānuitia ana mō ngā rango karu tirotiro me ngā rango waipēhi.

Ngā āhuatanga o te ngongo whakarewa matao + SR:

Te pumau o ngā āhuatanga kua whakapaitia
Te whakaiti i te ahotea toenga
He pai ake te mahi miihini
Mahi ā-mīhini ōrite

 

Te Tukanga Hanga o te Ngongo Whakarewa Matao DIN EN 10305-2

He maha ngā mahi whakaputa tika e hiahiatia ana mō te hanga ngongo whakarewa matao.

Kōwhiringa Rauemi Mata

Ka tīpakohia ngā koiri maitai kounga teitei kia rite ki ngā whakaritenga DIN EN 10305-2.

Te Hanga Ngongo

Ka hangaia ngā rīpene maitai hei ngongo mā te whakamahi i te hangarau whakarewa auau teitei.
