s275jr carbon steel sheet, No. 55 steel is a fully static steel manufactured by the electric furnace, open hearth or pure oxygen converter steelmaking method. It has the characteristics of excellent workability and uniform metallographic structure. s275jr carbon steel sheet, No. 55 steel is cheap and easy to process, and is suitable for surface hardening treatments such as high frequency quenching and flame quenching.
On October 30, the Ministry of Ecology and Environment issued the "Action Plan for Comprehensive Control of Air Pollution in the Yangtze River Delta Region in the Fall and Winter of 2020-2021". The "Plan" stated that the steel production capacity of Tianjin will be controlled at 15 million tons by the end of December 2020. Around this time, Hebei’s steel production capacity will be controlled within 200 million tons, and the elimination of 4.3-meter coke ovens with longer furnace age and poor furnace conditions will be accelerated, and independent coking companies will gradually withdraw.
