The manufacturing process and normalizing technology of 08CuPVRE weathering corrosion

ASME SA537 pressure vessel uses heat-treated carbon-manganese-silicon steel plate.The steel plates supplied by this standard are divided into three categories, namely SA537Gr1, SA537Gr2, and SA537Gr3. The maximum thickness of steel plates corresponding to these three grades is limited to: SA537Gr1 is not more than 100mm;The thickness of SA537Gr2 does not exceed 150mm;The thickness of SA537Gr3 does not exceed 150mm.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of 08CUPVRE weathering corrosion etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.

Now many manufacturers will use CNC equipment to complete the steel plate cutting processing, this processing method is also gradually increasing, but if you want to make the processing effect meet the specifications and standards, the control requirements of operation technology are also relatively high. Now there are many kinds of steel plate cutting, during the actual processing, it is necessary to select the appropriate processing method according to the cutting requirements of steel plate, so as to achieve the ideal processing effect for 08CUPVRE weathering corrosion.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
