Chromium element (Cr element) can improve the strength and hardness of A573 grade 70 plate, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;
We can cut the large steel plates A573 grade 70 plate by your requirements, but to the width and length your demand; we can make the surface of the cut steel plate to be bright by milling and grinding, also can make holes and make angle degrees, and can weld by your drawing. For the A573 grade 70 plate product thickness under 30mm, we mainly cut by laser cutting; for thickness over 30mm, mainly OXY-cut, flame cutting. The processing plates conclude cutting the larger plate into the small sizes customer demand, cut by drawing, cut to special sizes, weld the cut parts by drawing.
The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length A573 grade 70 plate is suitable for the length required by the construction of steel pipes.
