09CuPTiRE-B steel for machinery manufacturing

The toughness index of Q345B steel should be tested by impact test at 20 ℃. Although the strength of Q345B steel and Q345A steel are the same, the S / P control of Q345B steel is more strict, and the ambient temperatures of 09CuPTiRE-B steel, Q345B steel and Q345A steel are different. The cold impact test refers to the impact test at a certain temperature to obtain the energy consumed by punching the specimen. The more energy consumed, the higher the toughness of the material. Q345A is not subject to impact test. So Q345B steel is better than Q345A steel.

With the development of China's 09CuPTiRE-B steel market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of 09CuPTiRE-B steel products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

The 09CuPTiRE-B steel stainless steel 2250 mm wide coil mill has advantages such as adapting to difficult-to-deform steel grades. The Liuzhou Iron and Steel Hot Rolling Leveler project designed and supplied by MCC South is equipped with the latest straightening and leveling process (LTP technology) developed by MCC South. The 09CuPTiRE-B steel performance stability, cost and various consumption indicators have reached the international advanced level.

The allowable temperature of 09CuPTiRE-B steel, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of 09CuPTiRE-B steel work, the actual stress of 09CuPTiRE-B steel under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of 09CuPTiRE-B steel under the temperature.

Our company will accept the product quality objection registration record, pass it to the 09CuPTiRE-B steel production unit and relevant departments, and timely coordinate the supervision of product 09CuPTiRE-B steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
