Product Description
Seamless steel carbon steel pipes manufactured through hot rolled, cold drawn, and extrusion processes, specifically designed for construction and building applications.
Grade: 20# (20 steel)
Standards: GB/T 8162, GB/T 8163, GB/T 3087
Characteristics: Approximately 0.2% carbon content with good overall performance in strength, plasticity, and weldability.
- GB/T 8162: Mechanical equipment parts, building structural frames, vehicle chassis components
- GB/T 8163: Low-pressure fluid transportation pipelines (water, gas, oil)
- GB/T 3087: Boiler flue tubes, low-temperature superheater tubes
Grade: Q235 (Grades A/B/C/D)
Standards: Mainly GB/T 8162
Characteristics: Yield strength 235MPa - the most widely used carbon structural steel.
Main Uses: Structural components including building steel frames, bridge supports, engineering machinery structural parts, and guardrails. Generally not used for fluid pressure pipelines.
Grade: 45# (45 steel)
Standard: GB/T 8162
Characteristics: Contains approximately 0.45% carbon (medium carbon steel). After heat treatment (quenching and tempering), achieves excellent mechanical properties with high strength and toughness.
Main Uses: Core material in machinery manufacturing for heavy-load components such as shafts, gears, connecting rods, piston rods, and hydraulic cylinders. Not used for pipeline transportation.
Grade: 20G (G stands for "Boiler")
Standards: GB/T 3087 (Low and Medium Pressure), GB/T 5310 (High Pressure)
Features: Optimized from 20 steel with strict requirements for chemical composition, grain size, and mechanical properties to ensure excellent heat resistance and long-term strength.
Main Applications: Specifically designed for superheater tubes, reheater tubes, water-cooled wall tubes, economizer tubes, and steam pipes in boiler equipment. Key material in power and heating industries.
Packing Details: Export standard package, bundled or as required.
Delivery Time: According to order quantity.
Shipping Methods:
- By sea (Container or Bulk)
