ASTM A500 Seamless Square Hollow Section Tube ASTM A500无缝方形空心管

ASTM A500 SHS Pipe is used in structural applications for its strength. The specification covers cold formed, welded and seamless carbon steel tubing for structural applications with round and shapes of Grade A, B, C or D. The A500 Grade B Square Tube is used for its known structural strength because of the geometric shape. The pipes come in 1/8 inches to 30 inches of nominal bore sizes.

ASTM A500 SHS管因其强度而用于结构应用。本规范涵盖了用于结构应用的冷成型、焊接和无缝碳钢管，其形状为圆形和A、B、C或D级。A500 B级方管因其几何形状而具有已知的结构强度。这些管道的公称孔径为1/8英寸至30英寸。

According to the chemical composition, tensile strength and heat treatment, A500 cold bending pipe is divided into four grades (A/B/C/D).Square and rectangular yield strength requirements are higher than for round tubes.The minimum copper content is optional.Class D must be heat treated.

根据化学成分、抗拉强度和热处理，A500冷弯管分为四个等级（A/B/C/D）。方形和矩形的屈服强度要求高于圆形管。最低铜含量是可选的。D类必须进行热处理。

Tensile strength refers to the amount of stretching stress a material can withstand before breaking or failing. The ultimate tensile strength of A500 carbon steel is calculated by dividing the area of the steel by the stress placed on it, which is expressed in terms of pounds or tons per square inch of material. Tensile strength is an important measure of A500’s ability to perform in an application.

抗拉强度是指材料在断裂或失效之前能够承受的拉伸应力。A500碳钢的极限抗拉强度是通过将钢的面积除以施加在其上的应力来计算的，应力以每平方英寸材料的磅或吨表示。抗拉强度是衡量A500在应用中性能的重要指标。

Square & Rectangle Tubing方形和矩形管材

Below are physical properties required to meet the three grades that we produce ASTM A500 square, rectangle and special shaped tubing to. A flattening test is not a standard requirement for non-round tubing produced to A500.

以下是我们生产ASTM A500方形、矩形和特殊形状管材所需的三个等级的物理性能。压扁试验不是生产A500的非圆形管材的标准要求。

Round Tubing圆形管材

Below are physical properties required to meet the three grades that we produce ASTM A500 round tubing to. A flattening test is also a standard requirement for round tubing produced to the A500 specification.、

以下是我们生产ASTM A500圆管所需的三个等级的物理性能。压扁试验也是按照A500规范生产的圆管的标准要求。
