I-China ingenamthungo kungenamthungo eshushu-dip ye-dip ye-daing kunye nomthengisi

Ingenamthungo kumbhobho we-dip-dip ye-dip

Inkcazo emfutshane:

Imibhobho yentsimbi engenamthungo yenjongo ngokubanzi ye-Steam, amanzi, igesi kunye nemigca yomoya kwiI-ASTM A53 / A53m-2012Umgangatho.

Isixa sezinto ezintlanu akufuneki sibe ngaphezulu kwe-1.00%.

B Kwonqamleza yonke i-0.01% kwi-carbon yekhabhoni, owona mxholo we-manganese ophezulu uvunyelwe ukuba anyuke nge-0.06%, kodwa owona mphezulu akanakuba ngaphezu kwe-1.35%.

C I-CAT i-0.01% ye-0.01% yomxholo wekhabhoni ephezulu iya kuvumela owona mxholo we-manganese owona mxholo we-0.06%, kodwa olona luninzi malungeke kwi-1.65%.
