P460NH Pressure Vessel Steel Plate

P460NH, inodaidzwa kuve nekushomeka kwegoho simba re460 MPa, imhando yepamusoro yekumanikidza mudziyo simbi giredhi yekushandisa mu boiler uye yekumanikidza ngarava kugadzira. Iyo yakajairika yezviyo simbi ine yakanaka weldability maitiro.

Dzimwe mhando dzegiredhi dzinosanganisira…
NL1 - yakanakira kushandiswa mukupisa kwakadzika
NL2 - yakanakira kushandiswa kunyanya kudziya kwakadzika

P460NH inoshandiswawo mukugadzira gasi rakavava apo simbi inozoedzwa HIC kuyera kuti zvinhu zvinokwanisa kutsemuka here hydrogen.
