Product Description

Steel plate for boiler and container: Q**5R?Q**5R These plates are widely used in oil, chemical industry, boiler and other industries to make reactor, heat-exchange facility, segregator, spherical tank, oil gas tank, liquid gas tank, nuclear energy reactor pressure vessel, boiler steam manifold, lp-gas bottle, high pressure-water conduit of hydropower, water wheel Tubine scroll and other equipment and structural members. Steel plate for boiler are mainly used for making various boilers and important accessories?As this plate works in the mild temperature (**0? below) under high pressure, it also stands the impact, fatigue-loading, water and gas corrosion that it requires to guarantee the strength, good welding and cold bending performance. Steel plate for container is mainly used for making petroleum, chemical gas separation and gas storage pressure vessels and other similar equipment. Generally, it works under constant pressure condition the **0kg/cm� even to **0kg/cm� within the temperature of ******0? that it requires the strength , good plasticity and toughness, also good cold bending and welding performance. Application of Q**5R: Q**5R is the common low-alloy steel, and regular steel for boiler and pressure container. The delivery status can be hot rolled or normalizing. Its performance is similar to that of Q**5 (*6Mn) whose yield strength is greater than **5Mpa, with its tensile strength to ******0, elongation greater than *1%, and its zero V-shaped impact power bigger than that *5J. Q**5R is the special steel plate for pressure container with **0MPa yield strength, and has good comprehensive mechanical and processing properties. The phosphorus and sulfur contained in it are lower than that of low-alloy steel plate Q**5 (*6Mn). In addition to the improvement of tensile strength and elongation requirements, it can also guarantee impact toughness. It is now the most widely used and the largest amount of special steel for pressure vessel.Q**5R is suitable for the making of boiler, oil and mesohigh container of chemical equipment. The delivery status of products can be hot rolled, controlled rolling or normalizing. Application of Q**5R: Q**5R accounts for a large percent of the steel plate. Container plate contains special elements and has good performance. It is mainly used for making pressure container, and different in selecting container materials according to the different uses, temperature and resistance to corrosion. The delivery status of products can be hot rolled, controlled rolling and normalizing and can also be reviewed for flaw detection regarding the agreement of the supplier and buyer. Q**5R is the new brand for now and its standard is GB*******8. Their materials are the same, but a different name. Q**5R with high strength, good ductility, toughness, and cold bend performance, welding performance, is fit for making boiler, oil and mesohigh boiler and container of chemical equipment.
