Application of cutting xar400 plate equivalent grades

The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.

SPV355 grade is a kind of steel for medium temperature pressure vessel of Japanese standard. The technical standard is JISG3115. It is widely used in petroleum, chemical, power station, boiler and other industries to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, equipment and components such as liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, and turbine volutes.

Tempering the important xar400 plate equivalent grades welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve xar400 plate equivalent grades strength, plasticity and toughness.

What is the difference between Q345B steel and Q345A steel? xar400 plate equivalent grades, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.

In the process of xar400 plate equivalent grades steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose xar400 plate equivalent grades different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.

Expect in the xar400 plate equivalent grades goods regardless quality be still on the price after-sales service we all will keep in the middle of go together of advantage position real attain the ream customer satisfaction.Our advantage is: experienced craftsmen xar400 plate equivalent grades product development technology, excellent production team, hand strict quality control, sales and after-sales service.
