Standard Specification for Uncoated, Weldless, 2-Wire and 3-Wire Steel Strand for Prestressed Concrete
N A910/A910M
Annotation
This specification covers two types and two grades of 2-wire and 3-wire, uncoated steel strand for use in prestressed concrete construction. The two types of strand are lowrelaxation and stress-relieved (normal-relaxation). Lowrelaxation is to be regarded as the standard type. Stressrelieved (normal-relaxation) strand will not be furnished unless specifically ordered. The two grades are 250 [1725] and 270 [1860]. Grades 250 [1725] and 270 [1860] have minimum tensile strengths of 250 ksi [1725 MPa] and 270 ksi [1860 MPa] respectively, based on the nominal area of the strand.
This specification is applicable for orders in either inch-pound units (as Specification A910) or in SI units (as Specification A910M).
The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the specification.

Стандартная спецификация для непокрытого, бесшовного, стального берега с 3 проводами и с 2 проводами для предварительно напряженного бетона
Эта спецификация касается двух типов и двух сортов непокрытого стального берега с 3 проводами и с 2 проводами для использования в предварительно подчеркнутом конкретном строительстве. Двумя типами берега является lowrelaxation и уменьшенный от напряжения (нормальное ослабление). Lowrelaxation должен рассматриваться как стандартный тип. Stressrelieved (нормальное ослабление) берег не будет предоставлен, если в частности не заказано. Эти два сорта 250 [1725] и 270 [1860]. Сорта 250 [1725] и 270 [1860] имеют минимальные пределы прочности 250 тысяч фунтов на квадратный дюйм [1725 МПа] и 270 тысяч фунтов на квадратный дюйм [1860 МПа] соответственно, на основе номинальной области берега.
