09cuptire-a grade standard mechanical tests

Normalizing process of S355J2 steel plate: normalize the S355J2 steel plate in the bottom furnace, normalizing temperature is 880-910℃, holding time is 1.8-2.2min/mm, that is to get the required S355J2 + N steel plate. 355j2 + N steel plate is mainly used in large machinery manufacturing, equipment base, large welded steel structure, construction, bridge and other fields. With the continuous development of economy and the large-scale demand of equipment, the demand of ultra thick 09CUPTIRE-A grade standard, S355J2 + N steel plate is increasing gradually.

Our company provides 09CUPTIRE-A grade standard, A302 gr. B boiler plate for customers all over the world, which is used for pressure vessels, boilers, tanks and heat exchangers in oil and gas projects. The boiler steel plate of ASTM A302 grade B /A302 gr. B can be rolled with a maximum thickness of 300 mm, and the steel performance, including mechanical properties and chemical composition, can be guaranteed to fully comply with ASTM A302 / A302M standard.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the 09CUPTIRE-A grade standard steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the 09CUPTIRE-A grade standard, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
