Where the 09CuPCrNi-A machinability is used

Pipeline steel 09CuPCrNi-A machinability is mainly used for the transportation of oil and natural gas. Pipeline steel (LPS) is mainly used for processing and manufacturing oil and gas pipelines. Oil and gas pipeline network is the most convenient and safe channel connecting the resource area and market area. Its rapid construction will not only relieve the pressure of railway transportation, but also help to ensure the safe supply of oil and gas market and improve the level and capacity of energy security.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of 09CuPCrNi-A machinability etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in 09CuPCrNi-A machinability etc. steel is strictly controlled.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the 09CuPCrNi-A machinability steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the 09CuPCrNi-A machinability steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
