Low-alloy structural steel plates are mainly used in machinery manufacturing and metal structural parts. Advantages of A514 grade Q QT steel plate, low-alloy structural steel plates: They have superior performance and light weight. Disadvantages of low-alloy structural steel plates: These steel plates are all killed plates. The molten steel is deoxidized before the production. When the molten steel is poured into the ingot mold, its reaction is relatively calm and there will be no boiling state. A514 grade Q QT steel plate, low-alloy structural steel plates price will be more expensive.
The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the A514 grade Q QT steel plate industry, keep pace with the times, and move towards a new course!
Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < A514 grade Q QT steel plate steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished A514 grade Q QT steel plate product packaging.
Corrosion resistance mechanism of A514 grade Q QT steel plate, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
