Hot Rolled Coils/High-strength low-alloy steel grades with its intended purpose structure is very good notch toughness in the design. /Medium & Heavy Plate/Its specific applicability notch toughness of high strength low alloy grades of steel, or based only on existing experience, combining test results or impact notched specimens considered. In order to meet very strict requirements for certain uses, production of some low alloy high strength steel with excellent notch toughness. For example, the current technique commonly used to control the production of hot-rolled steel used in the manufacture of low-welded pipelines  degree steel plates, steel pipes need to meet the requirements for this standard of notch toughness requirements. Some low- plate thickness of its plastic - brittle transition temperature below -60 ℃. Some high-strength low-alloy grades Jing tension member at the time for major highway bridges, must satisfy -12 ℃ ~ -21 ℃ impact performance requirements.  Hot Rolled Coils price
