astm a193 grade B7m threaded rod and bar
astm a193 grade b7m Steel Threaded Rod is kind of threaded rod different from astm a193 grade b7. The differences such as:
Mechanical properties little difference: B7M Threaded Rods has a minimum tensile strength of 690MPa under 4", but B7 is 795MPa min from 2 1/2" - 4". B7M hardness is 235HB max, but B7 hardness is 321HB or 35HRC.
astm a193 grade b7m Threaded Rod we produce is manufactured with rolled threads instead of cut, free from tears or tool marks typically found in cut threads. So the threaded rods are smoother and have less surface imperfections that may cause possible failure in severe service applications.
