Q235 Q345 20# 45# OD 10mm 12mm Precision Carbon Seamless Steel Pipe
Detailed Image:
Description:
Q235 and Q345 are common carbon structural steels in China, which have different strengths and toughness. The Q235 is suitable for general structural applications, such as buildings and bridges, and its relatively low cost. Whereas, Q345 is a low-alloy high-strength structural steel, which is mainly used in structures that bear larger loads, such as large buildings, bridges, and heavy machinery.
20# and 45# are two other steel grades, and they also have different strength and toughness. 20# is a high-quality carbon structural steel, which has low carbon content and good mechanical properties, and is mainly used to manufacture precision parts, pressure vessels and pipelines. 45# is medium carbon steel, which has good mechanical properties, such as high strength and toughness, and is often used in the manufacture of gears, shafts, connecting rods and other mechanical parts that need to withstand greater impact and pressure.
The precision seamless carbon steel pipes introduced in this article are available in outer diameters of 10mm and 12mm, respectively, and are suitable for pipes and piping systems in various industrial and engineering fields. They have good mechanical properties and durability, can withstand high pressures and high temperatures, and are one of the commonly used materials in industrial and engineering fields.
Q235, Q345, 20#, and 45# are four different grades of precision seamless carbon steel pipes with different strength and toughness, which are suitable for pipes and piping systems in various industrial and engineering fields.
Specifications:
| Grade | Carbon Content (%) | Yield Strength (MPa) | Outer Diameter (mm) | Wall Thickness (mm) |
|---|---|---|---|---|
| Q235 | ~0.15-0.25 | 235 | 10 | 1 |
| Q235 | ~0.15-0.25 | 235 | 12 | 1.5 |
| Q345 | ~0.20-0.30 | 345 | 10 | 1.5 |
| Q345 | ~0.20-0.30 | 345 | 12 | 2 |
| 20# | ~0.18-0.23 | - | 10 | 1 |
| 20# | ~0.18-0.23 | - | 12 | 1.5 |
| 45# | ~0.42-0.50 | - | 10 | 1.5 |
| 45# | ~0.42-0.50 | - | 12 | 2 |
These pipes are available in various grades including Q235, Q345, 20#, and 45#, each designed to meet specific strength and performance requirements. The carbon content and yield strength vary depending on the grade selected. Additionally, the outer diameter and wall thickness are available in 10mm and 12mm variants to accommodate different application needs.
Key Features:
High precision: The outer diameter size is accurate, which can meet the application scenarios with high dimensional accuracy requirements.
Good mechanical properties:
The steel pipe made of Q235 has certain strength and good plasticity, and has good welding performance.
The steel pipe made of Q345 has high strength and superior comprehensive mechanical properties.
20# steel has good strength, toughness and plasticity.
45# steel has higher strength and hardness.
Seamless structure: There are no welds, the overall structure has good continuity, and can withstand high pressure and stress, reducing the risk of leakage and rupture.
Good processability: convenient for all kinds of machining and cold deformation treatment.
Corrosion resistance: It has a certain corrosion resistance under normal environmental conditions.
Wide applicability: It can be used in many fields such as machinery manufacturing, automobile industry, aerospace, petrochemical industry, etc., to meet the needs of different working conditions.
Application:
Building structure: As a structural part such as beams, columns, supports, etc., it provides strength and stability, such as frame structures in residential buildings, bridges, and industrial buildings.
Machinery manufacturing: In mechanical parts, such as gears, shafts, pump shafts, etc., where rotation and pressure need to be subjected.
Oil and gas pipelines: Due to their pressure resistance and corrosion resistance, they are commonly used in pipeline systems that transport fluids such as oil, gas, and water.
Automotive industry: places where automotive structural parts, such as frames, suspension systems, etc., need to withstand shock and vibration.
Chemical equipment: In chemical reactors, storage tanks, pipelines and other equipment, these steel pipes have good corrosion resistance due to the corrosiveness of the chemical environment.
Water treatment and water supply and drainage systems: used to transport water or wastewater treatment pipelines, which require high strength and corrosion resistance.
Thermal systems: Used as thermal pipes in heating, cooling, and steam transfer systems.
Aerospace: Although used in smaller amounts, these high-strength materials may also be used in certain structural parts of aerospace.
Steel structure engineering: In large steel structures, such as gymnasiums, airports, etc., as the main load-bearing structure.
Conclusion:
These precision carbon seamless steel pipes are ideal for use in industries such as construction, machinery, automotive, and more, where high-quality, reliable piping solutions are essential. Q235, Q345, 20#, and 45# are four different grades of precision seamless carbon steel pipes with different strength and toughness, which are suitable for pipes and piping systems in various industrial and engineering fields.
