S355G10 + M steel plate is for marine engineering. "S" indicates structural steel, "355" indicates minimum yield strength of steel plate, and "G10" indicates mechanical function test that imitates post-weld heat treatment. "M" indicates control rolling. S355G10 + M plate is structural steel for marine engineering and belongs to European standard high-strength structural steel. S355G10 + M steel plate has good mechanical function, welding function and technological function.

The 1.8974 steel for large truss truck boom, wear-resistant steel plate has the characteristics of high strength, impact resistance, beautiful appearance, high performance, high efficiency, and high cost performance, and has a broad application prospect. The wear-resistant steel plate adopts a combination of plate and beam as a whole to carry a fully welded structure. Since the plate used is thinner, in order not to reduce the strength of the plate and reduce the deformation, try to use spot welding to form a cavity, which is the structural feature and technical key of the wear-resistant steel .

In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of 1.8974 steel for large truss truck boom high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Anshan Iron and Steel's 4300 mm rolling mill, Shagang's 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's 1.8974 steel for large truss truck boom technical equipment.

The chemical composition difference between 1.8974 steel for large truss truck boom, Q235B and 20# steel is as follows:
The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%.
The difference of mechanical properties between 1.8974 steel for large truss truck boom, Q235B and 20# steel is as follows:
The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
