How stainless steel is made - material, …

I am a civil engineering trainee and i was surfing the net for the process of manufacturing steel, and i found that this site was near perfect. The info was great and very easy to read. However, i thought i t would also be useful tyo include some of the uses of stainless steel, im sure there are too many to mention, thats probably why you have stated the FUTURE. but if u included a broad range

What is TMT Bar? | TMT bar - SR - SR Steel

TMT bars or Thermo-Mechanically Treated bars are high-strength reinforcement bars having a tough outer core and a soft inner core. The very first step of the manufacturing process involves passing the steel wires through a rolling mill stand. Thereafter, these rolled steel wires are again passed through the Tempcore water cooling system. While passing the wires through the
