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管因其強(qiáng)度而用于結(jié)構(gòu)應(yīng)用。本規(guī)范涵蓋了用于結(jié)構(gòu)應(yīng)用的冷成型、焊接和無縫碳鋼管，其形狀為圓形和A、B、C或D級(jí)。A500 B級(jí)方管因其幾何形狀而具有已知的結(jié)構(gòu)強(qiáng)度。這些管道的公稱孔徑為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.

根據(jù)化學(xué)成分、抗拉強(qiáng)度和熱處理，A500冷彎管分為四個(gè)等級(jí)（A/B/C/D）。方形和矩形的屈服強(qiáng)度要求高于圓形管。最低銅含量是可選的。D類必須進(jìn)行熱處理。

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.

抗拉強(qiáng)度是指材料在斷裂或失效之前能夠承受的拉伸應(yīng)力。A500碳鋼的極限抗拉強(qiáng)度是通過將鋼的面積除以施加在其上的應(yīng)力來計(jì)算的，應(yīng)力以每平方英寸材料的磅或噸表示?？估瓘?qiáng)度是衡量A500在應(yīng)用中性能的重要指標(biāo)。
