ST52/45#/Q345/16Mn seamless steel pipes

Quick Detail:

Seamless steel pipes are made of a whole round steel perforated. Steel pipes with no welds on the surface are called seamless steel pipes. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, jacked pipes, etc. According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special-shaped. Special-shaped pipes have various complex shapes such as square, oval, triangle, hexagon, melon-shaped, star-shaped, and finned pipes. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

Q345 steel pipe, also known as 16Mn, 16Mn seamless steel pipe is an ordinary low alloy steel. It is a commonly used steel for boilers and pressure vessels. It is hot rolled or normalized. It is a low alloy steel with low Mn content. The performance is similar to 20G (412-540), the tensile strength is slightly stronger (450-655), and the elongation is 19-21%, which is worse than 20G which is more than 24%.

16Mn seamless steel pipe is a special plate for pressure vessels with a yield strength of 340MPa. It has good comprehensive mechanical properties and process performance. The phosphorus and sulfur content are slightly lower than ordinary 16Mn steel. In addition to the tensile strength and elongation requirements being higher than ordinary 16Mn steel, impact toughness is also required to be ensured. It is the most widely used and widely used special steel plate for pressure windows in my country.

45# steel: average carbon content is 0.42-0.50%, average silicon content is 0.17-0.37%, average manganese content is 0.50-0.80%, average sulfur content <=0.035%, average phosphorus content <=0.035% , average chromium content <=0.25%, average nickel content <=0.2545 steel
