P460NH Nrụgide Vessel Steel efere

P460NH, nke a na-akpọ maka inwe ike mkpụrụ kacha nta nke 460 MPa, bụ ọkwa nchara nrụgide dị elu maka iji na-esi mmiri ọkụ na nrụpụta ụgbọ mmiri. Ọ bụ ezigbo ọka nchara nchara nke ọma nwere njirimara weldability dị mma.

Ụdị ọkwa ndị ọzọ gụnyere…
NL1 - dị mma maka iji na obere okpomọkụ
NL2 - dị mma maka ojiji na karịsịa obere okpomọkụ

A na-ejikwa P460NH na ngwa gas utoojoo ebe ígwè ga-abụ HIC A nwalere iji chọpụta ihe ndị nwere ike ịkpata mgbawa hydrogen.
