钢，其中切断型钢纤维应用广泛，抗拉强度高。以低碳合金为基材，在金属晶体温度一下使用冷拔技术生产出的切断型钢纤维，抗拉强度可达1150-3000MP。广泛应用于工业地坪（物流、冷库、室外、仓储）加固以及开裂情况的改善。
Steel, among which cut steel fibers are widely used and have high tensile strength. The cut steel fiber produced by cold drawing technology with low-carbon alloy as the base material can reach a tensile strength of 1150-3000MP below the temperature of the metal crystal. Widely used for reinforcing industrial floors (logistics, cold storage, outdoor, storage) and improving cracking conditions.
以切断细钢丝法、冷轧带钢剪切、钢锭铣削或钢水快速冷凝法制成长径比（纤维长度与其直径的比值，当纤维截面为非圆形时，采用换算等效截面圆面积的直径）为30～100的纤维。因制取方法的不同钢纤维的性能有很大不同，如冷拔钢丝拉伸强度为380-3000MPa、冷轧带钢剪切法拉伸强度为600-900MPa、钢锭铣削法为700MPa；钢水冷凝法虽为380MPa，但是适合生产耐热纤维。
Fibers with a length to diameter ratio (the ratio of fiber length to diameter, converted to equivalent cross-sectional area diameter when the fiber section is non circular) of 30-100 are produced by cutting thin steel wires, cutting cold rolled strip steel, milling steel ingots, or rapid condensation of molten steel. The performance of steel fibers varies greatly due to different production methods, such as the tensile strength of cold drawn steel wire is 380-3000MPa, the tensile strength of cold rolled strip steel by shear method is 600-900MPa, and the tensile strength of steel ingot milling method is 700MPa; Although the steel condensation method is 380MPa, it is suitable for producing heat-resistant fibers.
