Dang Steel, a reputable steel supplier and manufacturer located in Da Nang, Vietnam, focuses on high-strength materials like S1100QL Steel Sheets and Plates. Renowned for its impressive tensile strength and durability, S1100QL stands out as one of the strongest quenched and tempered structural steels on the market. Dang Steel offers S1100QL in a variety of sizes and thicknesses, customized to fit the specific needs of clients in construction, transportation, defense, and heavy engineering. With a strong commitment to quality, precise processing, and quick delivery, Dang Steel has become a go-to partner for industries across Vietnam and Southeast Asia that require ultra-high-strength steel solutions.
S1100QL is an ultra-high-strength quenched and tempered structural steel known for its remarkable mechanical performance. Its typical chemical makeup includes carbon (max 0.22%), manganese (up to 1.65%), silicon (max 0.80%), along with alloying elements like chromium, nickel, molybdenum, and boron to boost strength and toughness. With a minimum yield strength of 1100 MPa and tensile strength ranging from 1250 to 1600 MPa, S1100QL maintains good toughness even in low temperatures and offers reasonable weldability when proper preheating and techniques are applied. These characteristics make it perfect for weight-sensitive, high-load applications where exceptional strength is essential.
