S620QL EN 10025-6 high strength steel steel weld pipe

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of S620QL EN 10025-6 high strength steel circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and S620QL EN 10025-6 high strength steel management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

15Mo3 steel manufacturing method: adopt oxygen top blown converter method, 182 open hearth method or 3666 to smelt in 3769 electric furnace. After negotiation with the customer, other equivalent methods can also be adopted.15Mo3 steel is used for heating surface pipes, economizers, superheaters, reheaters, etc. of high-pressure boilers S620QL EN 10025-6 high strength steel (working pressure is generally above 9.8MPa, working temperature is between 450 ℃ ~ 650 ℃).

Automobile girder steel is a kind of low alloy hot-rolled steel plate with thickness of 2.5-12.0 mm for manufacturing automobile girder (longitudinal beam and cross beam). Due to the complex shape of automobile girder, good stamping performance is required in addition to high strength and cold bending performance for automobile girder steel. The S620QL EN 10025-6 high strength steel, medium thick and heavy steel plates are mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest S620QL EN 10025-6 high strength steel processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain S620QL EN 10025-6 high strength steel by rolling method.

Q550C steel belongs to low alloy high strength steel. Chemical composition of Q550C steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 0.80, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. Mechanical properties of Q550C steel: yield strength ≥ 550 MPa, tensile strength 600-780 MPa, elongation after fracture ≥ 16%, impact energy ≥ 55J. S620QL EN 10025-6 high strength steel, Q550C steel is mainly used for manufacturing various large-scale engineering structural components and construction machinery. Due to its high strength, Q550C steel can meet the requirements of large-scale and lightweight construction machinery.
