Banyere ihe onwunwe nke Cr Mo pipe, enwere ọtụtụ ihe igwe na-emetụta ya. Mmekọrịta dị n'etiti akụrụngwa nke ọkpọkọ na ihe metal bụ isi dị ka n'okpuru:

Carbon (C): Ọdịnaya carbon na nchara na-abawanye, ebe mkpụrụ osisi, ike tensile na ike na-abawanye, mana plasticity na mmetụta mmetụta na-ebelata. Mgbe ọdịnaya carbon karịrị 0.23%, arụ ọrụ ịgbado ọkụ nke ígwè na-akawanye njọ, yabụ ọ bụrụ na ejiri ya maka ịgbado ọkụ Ọdịnaya carbon nke obere ihe nchara nchara anaghị agafe 0.20%. Ọdịnaya carbon dị elu ga-ebelata ikuku corrosion nchara nke igwe, na nchara carbon dị elu na mbara igwe mepere emepe dị mfe nchara; na mgbakwunye, carbon nwere ike dịkwuo oyi brittleness na ịka nká uche nke ígwè.
Silicon (Si): A na-agbakwunye silicon dị ka onye na-ebelata ihe na deoxidizer na usoro nchara, ya mere ígwè e gburu egbu nwere 0.15-0.30% silicon. Silicon nwere ike imeziwanye oke ngbanwe, ebe mkpụrụ na ike ike nke ígwè, yabụ a na-eji ya eme ihe dị ka igwe na-agbanwe agbanwe. Mmụba nke silicon ga-ebelata ọrụ ịgbado ọkụ nke ígwè.
Manganese (Mn). N'ime usoro nchara, manganese bụ ezigbo deoxidizer na desulfurizer. N'ozuzu, ígwè nwere 0.30-0.50% manganese. Manganese nwere ike ime ka ike na ike nke ígwè dịkwuo ike, mee ka ígwè dị ike dịkwuo elu, mee ka ọrụ ọkụ na-arụ ọrụ nke ígwè na-arụ ọrụ, ma belata ọrụ ịgbado ọkụ nke ígwè.
Phosphorus (P): N'ozuzu, phosphorus bụ ihe na-emerụ ahụ na ígwè, nke na-eme ka nchara oyi na-agbaji, na-emebi ọrụ ịgbado ọkụ, na-ebelata plasticity, ma na-eme ka arụ ọrụ na-ehulata oyi. Ya mere, ọdịnaya nke phosphorus dị na ígwè na-achọkarị ka ọ bụrụ ihe na-erughị 0.045%, na ihe achọrọ maka ígwè dị elu dị ala.
Sulfur (S): Sulfur bụkwa ihe na-emerụ ahụ n'okpuru ọnọdụ nkịtị. Mee nchara na-ekpo ọkụ na-ekpo ọkụ, belata ductility na ike siri ike, ma na-akpata mgbawa n'oge a na-akpụ akpụ na ntụgharị. Sulfur na-emebikwa arụmọrụ ịgbado ọkụ, na-ebelata nguzogide corrosion. Ya mere, a na-achọkarị sulfur ọdịnaya ka ọ bụrụ ihe na-erughị 0.045%, na ihe achọrọ maka ígwè dị elu dị ala. Ịtinye 0.08-0.20% sọlfọ na nchara nwere ike imeziwanye machinability, na a na-akpọkarị ya nchara nchara.
Vanadium (V): Ịtinye vanadium na nchara nwere ike imezi ọka ihe owuwu ma melite ike na ike.
Niobium (Nb): Niobium nwere ike nụchaa ọka ma melite arụmọrụ ịgbado ọkụ.
Ọla kọpa (Cu): Ọla kọpa nwere ike melite ike na ike. Ihe ọghọm ya bụ na ọ na-enwekarị ọkụ ọkụ na-ekpo ọkụ n'oge a na-arụ ọrụ ọkụ, na ọdịnaya ọla kọpa na nchara nchara na-adịkarị elu.
Aluminom (Al): Aluminom bụ deoxidizer a na-ejikarị na ígwè. A na-agbakwunye obere aluminom na nchara iji mee ka ọka dị mma ma melite mmetụta siri ike.
