S420NL simbi ndiro

S420NL simbi yakanaka weldability yemaitiro simbi giredhi. Zvinodiwa zvakajairika zvearc welding yesimbi dzakatsanangurwa zvichave sekupihwa mu EN 1011-2. Enzanisa iyo S355N, S420NL simbi giredhi ine goho rakawanda uye kusimba kwekusimba. Giredhi rakaenzana reS420NL iS420ML.

S420NL Simbi ndiro
S420NL simbi yakanaka weldability yemaitiro simbi giredhi. Zvinodiwa zvakajairika zvearc welding yesimbi dzakatsanangurwa zvichave sekupihwa mu EN 1011-2.
Enzanisa iyo S355N, S420NL simbi giredhi ine goho rakawanda uye kusimba simba. Giredhi rakaenzana reS420NL iS420ML.
Gnee simbi ine ruzivo rwakawanda mukugadzira S420NL. 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.

Chemical kuumbwa & Mechanical pfuma

Nezve S420NL 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 %
S420NL	0.200	0.600	1.0-1.7	0.025	0.030	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:

Giredhi	Hukobvu(mm)	Min Yield (Mpa)	Tensile(MPa)	Elongation(%)	Min Impact Energy
S420NL	8mm-100mm	360Map-420Mpa	520-680Mpa	19%	-50	27J
