S550 steel shot wear plate powerful company

Wear resistant steel plate is a kind of special plate product specially used under the condition of large area wear. At present, the commonly S550 steel shot used wear-resistant steel plate is a plate product made by overlaying a certain thickness of hard and wear-resistant alloy wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. The wear-resistant steel plate S550 steel shot consists of two parts: carbon steel plate and alloy wear-resistant layer.

Oxygen is a harmful element in S550 steel shot steel. With the increase of oxygen content, the strength of S550 steel shot steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of S550 steel shot steel.

Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < S550 steel shot 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 S550 steel shot product packaging.
