How heavy is S960QL steel?

How heavy is S960QL steel?

S960QL steel's weight depends on its dimensions, but its density is around 7.84 g/cm³ (or 7840 kg/m³), similar to other steels, making it heavy but strong for its weight; for example, a 1-inch thick plate can weigh over 1,300 lbs/sq. ft., but you calculate specific weight by multiplying volume by this density, often expressed as pounds per square foot per inch of thickness (around 40-42 lbs/ft²/inch).

Grade 960QL is a high strength structural steel in the quenched and tempered condition which gives the material excellent strength and abrasion resistance. S890QL is a water quenched & tempered steel which complies with the EN10025:6:2004 specification. Due to the nature of the material it is used extensively in the heavy transport, lifting and mining industry, where huge payloads and risk of material deterioration through excessive abrasion is commonplace. Produced in accordance with EN10025:6:2004, S890QL has good bending and welding capabilities.

S960QL stands as a pinnacle of metallurgical engineering, classified as a high-yield, quenched, and tempered structural steel under the European standard EN 10025-6. The alphanumeric designation "S960QL" provides a comprehensive summary of its mechanical prowess: the "S" denotes its identity as a structural steel, while "960" represents its staggering minimum yield strength of 960 megapascals (MPa) for plate thicknesses up to 50 mm. The "Q" signifies the specific heat treatment process-quenching and tempering-which involves heating the steel to a high temperature and then cooling it rapidly in water or oil, followed by reheating to a lower temperature to achieve a precise balance of hardness and ductility. Finally, the "L" indicates its exceptional low-temperature toughness, with guaranteed impact energy values tested at temperatures as low as -40°C.

In the mining and earthmoving sectors, S960QL proves its worth in the most punishing environments. It is frequently utilized for the wear-resistant liners of mining trucks, the structural frames of massive excavators, and hydraulic roof supports in underground mines. The material's ability to withstand extreme stress and impact without cracking is vital for safety and equipment longevity. Furthermore, its "L" designation ensures that machinery operating in arctic or high-altitude environments remains structurally sound and resistant to brittle fracture. Whether it is used in the construction of offshore platforms, high-rise building joints, or specialized military vehicles, S960QL enables the creation of structures that are lighter, stronger, and more sustainable than ever before.

 How heavy is S960QL?

S960QL is a high-strength structural steel, so its "weight" depends on its dimensions (thickness, width, length), but its density is around 7.84 g/cm³ (490 lbs/ft³), meaning a 1-inch thick plate weighs approximately 40.8 lbs per square foot (658 kg/m²), with specific weights varying by thickness and product form (plate, tube).

 What temperature is S960QL?

S960QL is a high-strength structural steel known for excellent performance at low temperatures, specifically tested for minimum impact energy at -40°C (-40°F), but it also handles moderate to high temperatures, with research studying its properties up to 900°C or more for applications like heavy machinery, though it's processed with high heat (e.g., 1350°C for austenitizing) and quenched for strength. Its "QL" designation confirms it's quenched and tempered for low-temperature toughness.

S960QL Steel Plate V Notch Impact Testing

1 What is the hardness of S960QL?

The hardness of S960QL steel is typically around 414 HBW (Brinell Hardness), though it's a high-strength structural steel defined by its yield strength of at least 960 MPa (depending on thickness) and delivered in a quenched and tempered (Q&T) condition, making it strong but requiring careful welding due to cold cracking risks.

2 What precautions should be taken when welding S960QL?

When welding S960QL high-strength steel, precautions focus on preventing hydrogen cracking and maintaining toughness, requiring thorough cleaning, using low-hydrogen consumables, strict heat input control (low interpass temps < 250°C), preheating (if needed), and slow, controlled cooling post-weld, alongside standard welding safety (PPE, ventilation) for hazardous fumes from primers or coatings.

3 What is the P number of S960QL?

The P-number for S960QL steel isn't a simple single digit like P1 or P2; instead, S960QL (a high-strength, quenched & tempered steel) typically falls into P-Group 1 (P1) in ASME Section IX for welding, as it's a low-alloy steel with limited alloying elements, though its high strength and specific composition often require referencing its EN designation (1.8933) and manufacturer data for precise welding procedures, generally grouping it with other low-alloy steels for basic classification.

4 Is S960QL carbon steel?

Yes, S960QL is a type of high-strength low-alloy (HSLA) carbon steel, specifically a quenched and tempered (Q+T) structural steel known for its exceptional yield strength (960 MPa), making it suitable for heavy-duty engineering applications like cranes, bridges, and mining equipment, balancing high strength with good toughness and weldability.
