Q355NHB steel plate is atmospheric corrosion-resistant steel plate, also known as weather-resistant steel plate. It is a low alloy steel series between general steel and stainless steel. Weather-resistant steel is made of ordinary carbon steel with a few corrosion-resistant elements such as copper and nickel. , Q355NHB steel sheet is featured by good toughness, plastic extension, forming, welding and cutting, abrasion, high temperature, fatigue resistance, etc,SPA-C normalized.

SPA-C normalized,Bridge steel plate is specially used for erecting railway or highway bridges. , bridge steel plate is required to have high strength and toughness to bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate used for bolt welding bridge should also have good welding performance and low notch sensitivity.

SPA-C normalized,Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < 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 product packaging.

API 5L steel is pipeline steel mainly for use in oil and gas industry. API 5L steel has PSL1 and PSL2 levels. For same API 5L steel grade, the carbon content for PSL1 is higher than PSL2. Meanwhile, the API 5L PSL2 steel has more strict requirement for P, S content than API 5L PSL1 steel. Therefore, API 5L PSL2 steel strength is higher than API 5L PSL1 steel strength. For example, API 5L X42 PSL2 yield strength is 317-524 MPa, tensile strength is 434-758 MPa. While API 5L X42 PSL1 yield strength is 290 MPa min. , tensile strength is 414 MPa min.
