S420N simbi ndiro

S420N simbi yakanaka weldability structural simbi giredhi. Zvinodiwa zvakajairika zvearc welding yesimbi dzakatsanangurwa zvichave sekupihwa mu EN 1011-2.
Enzanisa iyo S355N, S420N simbi giredhi ine goho rakawanda uye kusimba kwesimba. Giredhi rakaenzana reS420N iS420M.

Gnee simbi ine ruzivo rwakawanda mukugadzira S420N. takashandira pamwe newuyang chigayo cheHBIS kugadzira hukuru hukuru 300mm muunyanzvi hwekugadziridza ma electroslag. Zvatinakira ndezvekuti taigona kupa zvinhu munguva yekukurumidza kuendesa, kunyangwe mundiro imwe mune yakajairwa yakatarwa.

Nezve S420N simbi ruzivo ruzivo, ndapota tarisa kune tekinoroji zuva mukutevera.

Iyo Chemical ndiyo yakakura kuumbwa kwekuongorora kwechigadzirwa:

Giredhi	C%	Si %	Mn %	P%	S %	V%	AL %	Cr %
S420N	0.200	0.600	1.0-1.7	0.030	0.025	0.020	0.020	0.300
	Cu %	Mo %	Nb %	Ni %	Ti %	N %
	0.550	0.100	0.050	0.800	0.050	0.025

The mechanical properties simbi ndiro

Giredhi	Hukobvu(mm)	Min Yield (Mpa)	Tensile(MPa)	Elongation(%)	Min Impact Energy
S420N	8mm-100mm	360Map-420Mpa	520-680Mpa	19%	-20	40J
	101mm-200mm	330Mpa-360Mpa	500-650Mpa	18%	-20	40J
	201mm-250mm	320Mpa-330Mpa	500-650Mpa	18%	-20	40J
Iyo min impact simba is longitudinal energy

Kuti uwane rumwe ruzivo muS420N setifiketi yemhando kana kubvunza mukukwikwidza zviri pamutemo kotesheni, ndapota taura nesu neemail.
