What is the high quality 16mo3 steel hot rolling

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 high quality 16Mo3 steel is suitable for the length required by the construction of steel pipes.

Expression method of pressure coefficient of seamless steel pipe: pressure P 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished high quality 16mo3 steel product packaging.

Phosphorus is a very harmful element in high quality 16mo3 steel steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of high quality 16mo3 steel steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

Since the beginning of this year, the global high quality 16mo3 steel steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global high quality 16mo3 steel steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
