1.Carbon steel pipe
1.1.Carbon steel pipe, generally at low temperature (less than -20℃) the use of carbon steel pipe should be GB6479 standard, only it provides for the material of low temperature impact toughness requirements GB3087 and GB5310 standard is specially set for boiler steel pipe standards.
1.2.Carbon steel pipe is made of carbon steel, with carbon content of about 005% ~ 135%.
1.3.Steel pipe according to the pipe material (namely steel) can be divided into: carbon tube and alloy tube, stainless steel tube and other carbon tube can be divided into ordinary carbon pipe and high quality carbon structure tube alloy tube can be divided into: low alloy tube, alloy structure tube, high alloy tube, high strength tube.
2.carbon steel pipe strong
2.1. Carbon steel pipe is strong, Q345 seamless pipe /Q345 thick wall pipe /Q345 seamless thick wall pipe/large diameter Q345 seamless pipe /Q345 carbon steel pipe is a low alloy series – low alloy high strength structural steel (GB/T1591-1994).
2.2. The “stainless steel tube” is the cathode, the “carbon steel tube” is the anode, the greater the potential difference between the two is the larger the galvanic corrosion tendency.
2.3. Carbon steel used in industrial steel materials carbon steel plays an important role in commonly used carbon steel carbon content is generally less than 13%, better strength and toughness compared with alloy steel, carbon steel smelting is simple, easy processing, cheap price, generally can meet the performance requirements, widely used.
3. What kind of pipe does carbon steel pipe belong to
3.1. Carbon steel pipe belongs to what kind of pipe, carbon steel pipe: a kind of steel pipe alloy, the production of common carbon steel pipe is generally divided into high, medium and low carbon three types of high carbon steel pipe carbon content is the highest, generally more than 06 percent, but we know that the higher the carbon content of its brittleness is greater, so high carbon steel pipe is generally not used for industrial production.
3.2 steel pipe 40cr meaning -40cr is 40 chromium, CR is the abbreviation of chrome (chromium), 40cr belongs to alloy steel Cr can increase the hardenability of steel, improve the strength and tempering stability of steel, has excellent mechanical properties section size or important tempering workpiece, should be used Cr steel but Cr steel has the second kind of tempering brittleness.
3.3. Carbon steel pipe is made of steel ingot or solid round steel perforated into wool tube, and then hot rolled, cold rolled or cold drawn carbon steel pipe is a kind of steel tube alloy, the production of common carbon steel pipe is generally divided into high, medium and low carbon three categories.
