Main application of JIS carbon steel SM570 CS plate

15MnNi steel plate is used for nuclear safety second and third grade pressure vessel steel. Since nuclear power equipment is used in harsh environments such as high temperature, high pressure and neutron radiation all year round, the steel JIS carbon steel SM570 CS plate for equipment manufacturing is required to have suitable strength, high toughness, and low brittle transition temperature. The characteristics of strong performance and anti-radiation ability and low alloy element content, so there are strict requirements in room temperature stretching, high temperature stretching, thickness direction stretching and hardness.

We are world class steel JIS carbon steel SM570 CS plate materials supplier. We are engaed in providing raw steel materials such as steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for JIS carbon steel SM570 CS plate quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build long-term cooperation with you.

Laser cutting JIS carbon steel SM570 CS plate has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the JIS carbon steel SM570 CS plate cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.

For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In JIS carbon steel SM570 CS plate, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.

Both parties shall confirm the JIS carbon steel SM570 CS plate material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the JIS carbon steel SM570 CS plate steel plant.
