The classification of scrap stainless steel is closely related to the use of stainless steel, mainly in the following sources:

 

1. Domestic garbage:

 

Waste stainless steel appliances (old materials) used in daily life, most of the scrap stainless steel imported from Japan in Japan, Korea belongs to this category, and can only be used as a charge. The main steel grades such as kitchen equipment and tableware are SUS304 and 430. The food processing industry mainly produces food processing machinery and containers, such as grain, beer and beverage, dairy processing equipment, and main steel grades such as quick-freezing refrigeration equipment, 304, 321 , 1cr13 and antibacterial. Ferritic stainless steel.

 

 

2. Industrial waste

 

Cutting industrial production, perforated waste (new materials) include some pipes, rods, plates, etc. that can be used directly, in small quantities. The urban landscape project is mainly composed of stainless steel welded pipes. The automotive industry is primarily ferritic stainless steel 409 for automotive exhaust pipes. Other industries such as urban water supply engineering, environmental protection and petrochemical, and electric power industries also have a lot of waste stainless steel. Oil, gas, acid pumps and containers are large markets for the production of waste stainless steel tanks, tubes, pumps and valves. The main steel grade is 18/8 stainless steel.

 

Due to various stainless steel scraps, it is necessary to strengthen the management of the classification, processing and storage of various alloy scraps.
