High strength Low alloy metal pipes care covered by specification ASTM A572. This specification houses multiple HSLA grades such as 42, 50, 55, 60, as well as 65. The grades in this specification will co-relate to the strength. For instance, the strength of ASTM A572 Grade 50 HSLA Pipe is about 380 Mpa.
Similarly, the strength of grades 42, 55, 60 & 65 in Mpa are as follows - 290, 380,415, and 450. Typically, the use of high-strength low-alloy or HSLA ASTM A572 Grade 55 is intended for applications in welded, bolted, or riveted constructions in either bridges or in buildings. Grades like these have additions of elements columbium & vanadium. As a microalloying element, adding colombium or niobium in ASTM A572 Grade 42 improves several properties like - its strength, toughness, formability, and enhancing its weldability. On the other hand, vanadium is a microalloying element that delays the onset of rust, and its addition in the ASTM A572 Grade 50 Pipe aids in stabilizing carbides. Other requirements according to this specification, the HSLA pipe astm a572 gr 50 type 2 include their general delivery, tensile, alloy content and test report.
