Uvavanyo loMgangatho weePipe zeNsimbi eziSikwere nezingunxande ze-ASTM A500:

Ulwakhiwo lweekhemikhali lwe-ASTM A500
Ibanga lentsimbi	C (ubuninzi.)%	Mn (ubuninzi.)%	P (ubuninzi.)%	S (ubuninzi.)%	Ithusi (ubuncinci)%
Ibanga A	0.3	1.4	0.045	0.045	0.18
Ibanga B	0.3	1.4	0.045	0.045	0.18
Ibanga C	0.27	1.4	0.045	0.045	0.18
Kunciphiso ngalunye lwe-0.01 yepesenti ngaphantsi komlinganiselo ochaziweyo wekhabhoni, ukunyuka kwe-0.06 yepesenti ngaphezu komlinganiselo ochaziweyo we-manganese kuvumelekile, ukuya kuthi ga kwi-1.50% ngohlalutyo lobushushu kunye ne-1.60% ngohlalutyo lwemveliso.

Iipropati zoomatshini zeMibhobho yoLwakhiwo oluMile
Ibanga lentsimbi	Unikeze Amandla umzuzu we-MPa	Tensile strength umzuzu we-MPa	Ukwandiswa ubuncinci %
Ibanga A	270	310	25 ubukhulu bodonga (T) obulingana okanye obungaphezulu kwe-3.05mm
Ibanga B	315	400	23 ubukhulu bodonga (T) obulingana okanye obungaphezulu kwe-4.57mm
Ibanga C	345	425	21 ubukhulu bodonga (T) obulingana okanye obungaphezulu kwe-3.05mm
