ST12 is German standard (DIN1623), It's ordinary cold rolled steel. In principle, ST12 can only be bent and formed, and no stamping is allowed.
Application: It is suitable for stress and pressure parts, as well as steam, water, gas and air pipelines for general purposes. A53 pipeline pipe belongs to American petroleum standard pipeline pipe. Pipeline pipe is used to transport oil, steam and water pumped out of the ground to oil and natural gas industrial enterprises through pipeline pipe. Pipeline pipe includes seamless pipe and welded steel pipe, with flat end, threaded end and socket end at the pipe end; The connection methods are end welding, coupling connection, socket connection, etc.
NM500 steel plate is a high-strength wear-resistant steel plate with high wear resistance.
NM500 wear-resistant steel plate is widely used in engineering machinery, environmental protection machinery, metallurgical machinery, abrasives, bearings and other product parts.
Carbon steel round welded pipe
Carbon steel pipes are pipes made of carbon steel. They are one of the most commonly used metal materials and have good mechanical properties, processing properties and corrosion resistance. According to the production method, it can be divided into two types: seamless steel pipe and welded steel pipe.
Black square tube is a type of pipe, usually made of materials such as carbon steel, stainless steel, or scrap metal. Its shape is square or rectangular, hence its name. Black square tubes have good compressive performance, bending resistance, tensile resistance, and wear resistance, and are widely used in fields such as construction, transportation, and agriculture.
Carbon Steel Square Welded Pipe
Carbon steel pipes are pipes made of carbon steel. They are one of the most commonly used metal materials and have good mechanical properties, processing properties and corrosion resistance. According to the production method, it can be divided into two types: seamless steel pipe and welded steel pipe.
Carbon Steel Square Seamless Pipe
Carbon steel pipes are pipes made of carbon steel. They are one of the most commonly used metal materials and have good mechanical properties, processing properties and corrosion resistance. According to the production method, it can be divided into two types: seamless steel pipe and welded steel pipe.
Seamless steel pipe is made of whole metal and has no seams on its surface. According to the production method, seamless pipe is divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking and so on. According to the cross-section shape, seamless steel pipe can be divided into two kinds: circular and irregular. The irregular pipe has many complex shapes, such as square, ellipse, triangle, hexagonal, melon seed, star and finned pipe. The maximum diameter is 650 mm and the minimum diameter is 0.3 mm. Depending on the use, there are thick-walled and thin-walled tubes. Seamless steel pipes are mainly used for petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.
SPCC carbon steel plate is generally used in the production of steel structures, vehicles, ships and bridges, and has good corrosion resistance and atmospheric corrosion resistance.
The tensile strength of ST42 Carbon Steel Pipe shall not be less than 42kgf/mm2, which is 420MPa.ST42 Carbon Steel Pipe is a German standard seamless steel pipe, which is widely used. German standard seamless steel pipes for general purposes are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for fluid transportation .
The better weldability also makes 4130 Carbon Steel Pipe a popular choice in the aerospace industry, which is used to manufacture commercial and military aircraft components requiring high strength and low weight. Examples include gears, piston pins, etc. Other uses of 4130 steel include auto parts, cutting tools and drilling machines.
