Export great 1.8941 steel to India

45MnB characteristics and applications: alloy structural steel has good hardenability, the critical hardenable diameter in oil reaches 17 ~ 31mm. The machinability of steel 1.8941 steel is good, the forging and heat treatment process performance is also good, the tendency of grain growth, oxidation, decarburization and heat treatment deformation is also small when heated. 45MnB steel is mainly used for gears on machine tools, spindles of drilling machines, turning shafts and cams of tractors.

At the same time of doing well in 1.8941 steel 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 1.8941 steel 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.

Last year, the technicians in the automation department of BBN STEEL closely combined the needs of the production line, based on the big data platform. It has successively developed more than 10 industrial software such as intelligent boiler combustion system, equipment full life cycle system, and integration of environmental protection management and control, which provide efficient and intelligent support for comprehensive support of high-end production line production and lays a solid foundation for high-quality development.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of 1.8941 steel etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
