S460 steel shot hot working

Hydrogen (H) is the most harmful element in general steel such as S460 steel shot. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing S460 steel shot steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.

According to the different manufacturing processes, there are hot rolled steel pipes and cold drawn S460 steel shot seamless steel pipes. BBN sells seamless pipes of different sizes, weights and grades. Customers can choose between black S460 steel shot line pipes and galvanized line pipes. From 2-3/8" to 24", steel grade A, B, X42, X80.

The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, S460 steel shot, steel structure products, and intimate after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our S460 steel shot steel mill.
