What is meaning of equivalent of p355gh steel

Pageviews:

Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following equivalent of P355GH steel basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.

Our quality control department will do inspection for details of the steel materials equivalent of p355gh steel before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

equivalent of p355gh steel, SA516 Gr 65 steel belongs to carbon steel plate for medium and low temperature pressure vessel, which is in accordance with American ASME standard. The minimum thickness of SA516 Gr 65 steel plate is 8mm, width is 1500 - 4000mm. The additional thickness direction (Z direction) tear resistance and wet hydrogen sulfide corrosion resistance (HIC + SSCC) can be put forward.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for equivalent of p355gh steel and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
