Attentions in machining ASME SA633 carbon steel plate sheet

Our quality control department will do inspection for details of the steel materials ASME SA633 carbon steel plate sheet 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.

Q420B material is a low-alloy high-strength structural steel. ASME SA633 carbon steel plate sheet, Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit. The tensile strength of Q235 steel is 235MPa, and the tensile strength of Q420B steel is 420MPa. Q420B low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good Cold forming performance and welding performance; has good corrosion resistance and certain wear resistance.

We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product ASME SA633 carbon steel plate sheet annual capacity is 200 thousand tons.

We do sand blasting and shop primer for various ASME SA633 carbon steel plate sheet steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer ASME SA633 carbon steel plate sheet thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.
