At the same time of doing well in 16Mo3 steel machinability production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the 16mo3 steel machinability technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
API 5L Gr. A is mainly used for steel of large diameter pipeline. 16mo3 steel machinability, API 5L Gr. A is mainly used for pressure liquid transportation, oil, natural gas, water and other liquid transportation, oilfield engineering, pipeline engineering, construction, steel pipe and oil and gas engineering using pipeline.
Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the 16mo3 steel machinability steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.
The steel such as 16mo3 steel machinability delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
