Kowiri tira fehokotaki'angaHikohiko
A317
GB/T E309Mo-15
AWS A5.4 E309Mo-15
Whakaahuatanga: Ko te A317 he hiko kowiri tira me te paninga konutai hauwai iti.Whakamahia te DCEP (te hiko tika o naianei pai).He pai ake te waikura, te kapiti, me te aukati waikura i te A302 na te mea kei roto i te konganuku te molybdenum.
Taupānga: Ka whakamahia mo te whakapiri i te ahua o te kowiri tira, te pereti maitai hiato me te rino rereke e atete ana ki te waikura waikawa pungatara (ammonia whanariki).
Te hanganga matū o te whakarewa whakarewa(%):
