Products, Characteristics & Applications
Hot Rolled Mild Steel
Mild Steel has a low carbon content and is relatively soft, having a tensile strength of no greater than 340 MPa. Its good elongation and great formability make the steel popular for many applications ranging from regular to sophisticated machining. Its most common application is automotive parts.
| Classification | Grade | Characteristics | Applications |

Hot Rolled High Strength Steel (HSLA)
High Strength Steel is made by adding silicon, manganese, nickel, chromium, copper and other elements to carbon steel containing 0.2 percent of carbon for higher performance. With a tensile strength of about 50 kg/mm2, this steel features a reasonable level of strength and toughness. High Strength Steel can be classified into bake-hardening steel, solid-solution strengthening and precipitation hardening steel. It also has many variants: BH (Bake-Hardenable) steel, HSLA (high strength low alloy), R (rephosphorized) steel, IF (Interstitial Free) HSS and ATOS (Automobile Structural) steel.
