3、1 This specification covers three Types and two Grades of cold formed electric-fusion (arc) welded high-strength low-alloysteel tubing of 50 ksi 345 MPa minimum yield point for use in welded or bolted construction of buildings and for generalstructural purposes.1.2 This tubing is produced in square

4、and rectangular sizes with a periphery of 200 in. 500 cm or less and a specified wallthickness of 1.00 in. 25 mm or less. Tubes are joined by two longitudinal electric-fusion (arc) welds. Circumferential welds aredisallowed. Sizes outside of those listed in Tables 4 and 5 may be ordered provided all

5、 other requirements of the specification aremet. Typical lengths are 15 to 50 ft. 5 to 15 m.NOTE 1Products manufactured to this specification may not be suitable for those applications such as dynamically loaded elements in weldedstructures, etc. where low-temperature toughness properties may be imp

(See Supplementary Requirement S1.)1.3 This specification covers the following Types:1.3.1 Type 1Welded with backing, backing left in the product,1.3.2 Type 2Welded with backing, backing removed,1.3.3 Type 3Welded without backing.1.4 Tubing is available in Grades 50 345 and 50W 345W. Grade 5

7、0 345 is manufactured from high-strength low-alloysteel. Grade 50W345W is manufactured from high-strength low-alloy steel with enhanced atmospheric corrosion resistance. (See10.1.2) The Grades may not be interchanged without approval of the purchaser.ASTM Specifications for plate that may be applied

8、to Grade 50 345 and 50W 345W are listed in Reference Documents and in Table 1.1.5 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contractspecifies the applicable M specification designation (SI units), the inch-pound units shall apply.

9、 The values stated in either SI unitsor inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values statedin each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining valuesfrom
