Scrap stainless steel refers to metal that is used for reprocessing in the furnace. Its main sources are stainless steel waste generated by industrial manufacturing and stainless steel technology, stainless steel equipment that is damaged and scrapped due to long-term use, and stainless steel utensils used in daily life. After being scrapped, they can only be reprocessed into other stainless steel products or products.

INDUSTRIAL WASTE STAINLESS STEEL

Urban landscape projects are mainly based on stainless steel welded pipes. The automotive industry is mainly ferritic stainless steel 409 for automobile exhaust pipes. Other industries such as urban water supply projects, environmental protection, petrochemicals, and power industries also produce a lot of waste stainless steel. The scraps (new materials) cut and stamped off during industrial production include some directly usable pipes, rods, plates, etc., which are relatively small in number. Pumps and containers for oil, gas, and acid are a large market that produces a large number of scrap stainless steel tanks, pipes, pumps, and valves. The main steel grade is 18/8 stainless steel.

LIFE WASTE STAINLESS STEEL

Scrapped stainless steel utensils used in daily life, etc. (old materials). After stainless steel is scrapped, it can only be recycled as furnace materials. Kitchen equipment, tableware, etc., the main steel grades are SUS304 and 430. The food processing industry mainly manufactures food processing machinery and containers, such as grain, beer and beverage, dairy processing equipment, quick-freezing and refrigeration equipment, etc. The main steel types are 304, 321, 1cr13 and antibacterial ferritic stainless steel.
