What is the maximum thickness of 17Mn4 pressure vessel steel sheet

ASTM A387 steel 17Mn4 pressure vessel steel sheet specification refers to 6 grades levels of alloy steel plate for elevated temperature applications, classified by chromium and molybdenum content, Grade 11 and Grade 12 has similar chemical content,they can be used in welded 17Mn4 pressure vessel steel sheet pressure vessels and industrial boilers, and mostly in oil gas and petrochemical industry, generally it is used for transportion of medium at high temperature.

The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel 17Mn4 pressure vessel steel sheet products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our 17Mn4 pressure vessel steel sheet business. We also provide third-party inspection and approval services and inventory management for our customers.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized 17Mn4 pressure vessel steel sheet are higher than that of annealed 17Mn4 pressure vessel steel sheet, but the elimination of internal stress is not as good as annealing. The normalizing operation of 17Mn4 pressure vessel steel sheet is simple, the cost is low, the productivity is high, and it is widely used in actual production.

Classification of 17Mn4 pressure vessel steel sheet, steel plate, including strip steel:
1. Classified by thickness: (1) thin plate (2) medium plate (3) thick plate (4) extra thick plate
2. Classification by production method: (1) hot rolled steel plate (2) cold rolled steel plate
3. Classification according to surface characteristics: (1) galvanized sheet (hot galvanized sheet, electro galvanized sheet) (2) tin plate (3) composite steel plate (4) color coated steel plate
4. Classification by use: (1) bridge steel plate (2) boiler steel plate (3) shipbuilding steel plate (4) armored steel plate (5) automobile steel plate (6) roof steel plate (7) structural steel plate (8) electrical steel plate (silicon steel sheet) (9) spring steel plate (10) others

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
