With the development of remote oil and gas fields, polar oil and gas fields, offshore oil and gas fields and acid oil and gas fields, oil and gas pipeline engineering is facing challenges of high-pressure transmission and harsh environment such as low temperature, large displacement, deep sea and acid medium. In order to ensure the enthusiasm and safety of pipeline construction and operation, the basic requirements and development trend of ASTM A572 high strength steel, pipeline steel are high strength, high toughness, large deformation, thick wall, high corrosion and good weldability.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This ASTM A572 high strength steel alloy steel ASTM A572 high strength steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
In order to improve the ASTM A572 high strength steel corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main ASTM A572 high strength steel coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking ASTM A572 high strength steel sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.
ASTM A588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the ASTM A572 high strength steel yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 ASTM A572 high strength steel has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.
