Incazelo yokwakheka kanye nenqubo yokukhiqiza amapayipi ensimbi yekhabhoni

Ipayipi Lensimbi Yekhabhoni liyipayipi elenziwe ngensimbi yekhabhoni njengento eyinhloko. Okuqukethwe kwayo kwekhabhoni kuvame ukuba phakathi kuka-0.06% no-1.5%, futhi liqukethe inani elincane le-manganese, i-silicon, i-sulfur, i-phosphorus nezinye izinto. Ngokwezindinganiso zomhlaba wonke (njenge-ASTM, GB), amapayipi ensimbi yekhabhoni angahlukaniswa ngezigaba ezintathu: insimbi yekhabhoni ephansi (C≤0.25%), insimbi yekhabhoni ephakathi (C=0.25%~0.60%) kanye nensimbi yekhabhoni ephezulu (C≥0.60%). Phakathi kwawo, amapayipi ensimbi yekhabhoni ephansi yiwona asetshenziswa kakhulu ngenxa yokukwazi kwawo ukucutshungulwa kahle kanye nokushintshwa.
