   In the recent past, HSS was commonly available in mild steel, such as A500 grade B. Today, HSS is commonly available in mild steel, A500 grade C. Other steel grades available for HSS are A847 (weathering steel), A1065 (large sections up to 50 inch sq made with SAW process), and recently approved A1085 (higher strength, tighter tolerances than ...

   Steel never turns into a liquid below this temperature. Pure Iron ('Steel' with 0% Carbon) starts to melt at 1,492 °C (2,718 °F), and is completely liquid upon reaching 1,539 °C (2,802 °F). Steel with 2.1% Carbon by weight begins melting at 1,130 °C (2,070 °F), and is completely molten upon reaching 1,315 °C (2,399 °F).

   The Raleigh Bicycle Company of Nottingham, England was a big customer for Reynolds 531 tubing used in their racing cycle range. Reynolds 531 has now been largely replaced in new frames by still-better steels. The latest, for race or sports frames, is Reynolds 953. [5] Reynolds worked closely with Carpenter Speciality Alloys to develop 953. It ...
