What characteristics should the S690QL1 mechanical properties have

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep S690QL1 mechanical properties processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and S690QL1 mechanical properties steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

Q960D quenched and tempered high-strength steel is used to make pressure shell parts, deep tide lifesavers, high-pressure structural parts, aerospace equipment, armored vehicles, and manufacturing various engineering machinery, such as drilling rigs, electric shovel, and Electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and wear-resistant structural parts.

Q345D seamless pipe has good comprehensive mechanical properties, low temperature impact toughness, cold stamping and cutting processability, weldability. In Q345D seamless pipe, Q is the abbreviation of yield strength, 345 is the yield strength value, that is, the yield strength of Q345D seamless pipe is 345 MPa, and D is the impact temperature, which is minus 20℃. S690QL1 mechanical properties, Q345D seamless pipe is widely used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, storage tanks, heavy machinery and equipment, mining machinery, power stations, plant structures, low-temperature pressure vessels, textile machinery parts, etc.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of S690QL1 mechanical properties nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of S690QL1 mechanical properties steel, can be used as an alloying element of low alloy steel.

20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, S690QL1 mechanical properties. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.

Expect in the S690QL1 mechanical properties goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen S690QL1 mechanical properties product development technology, excellent production team, hand strict quality control, sales and after-sales service.
