20MnG High Pressure Boiler Tube Alloy Seamless Pipe For Boilers And Heat Exchangers

Material

20MnG is a high-quality alloy steel material commonly used for manufacturing high-pressure boiler tubes and seamless pipes. It is designed to withstand high temperature and pressure conditions typically found in boilers and heat exchangers.

Specification

  • Type: Alloy Steel Seamless Pipe
  • Standard: Typically manufactured as per ASTM, EN, GOST, JIS, GB standards
  • Diameter: Varies depending on application (commonly ranges from 20 mm to 273 mm OD)
  • Wall Thickness: Varies according to pressure requirement
  • Length: Usually supplied in random or fixed lengths

Chemical Composition

Element C (%) Mn (%) Si (%) P (%) Max S (%) Max Other Elements (max)
20MnG 0.17–0.24 1.10–1.40 0.17–0.37 0.035 0.035 Cu, Ni, Cr as controlled impurities

Mechanical Properties

Property Value Test Standard
Tensile Strength (Rm) 410–540 MPa ASTM / EN / GB
Yield Strength (Rp0.2) Minimum 245 MPa ASTM / EN / GB
Elongation (A5) Minimum 20% ASTM / EN / GB
Hardness Typically less than 200 HB ASTM / EN / GB

Key Features

  • High Strength: Suitable for high pressure and temperature environments.
  • Excellent Weldability: The alloy design ensures good weldability for easy fabrication.
  • Corrosion Resistance: Adequate resistance to oxidation and corrosion in boiler environments.
  • Seamless Pipe: Manufactured without weld seam, enhancing durability and reliability.
  • Thermal Stability: Maintains mechanical properties under cyclic temperature conditions.
  • Good Toughness: Ensures resistance to crack propagation and mechanical shocks.

Equivalent Grades

Standard Equivalent Grade
ASTM A335 P11 / P22 (similar application range)
EN 20MnG (1.0421 - similar specs)
GOST 20MnG / 20MnGB
JIS SCM420 / SCM430 (approximate equivalent)
GB 20MnG

Application

  • High-Pressure Boilers: Used in manufacturing of boiler tubes that operate under high steam pressures.
  • Heat Exchangers: Suitable for seamless piping in heat exchangers requiring resistance to high temperatures and pressure.
  • Superheater Tubes: Ideal for superheater and reheater tubes used in power plants.
  • Petrochemical Industry: Used for pipelines subjected to thermal and mechanical stress.
  • Other Industrial Boilers: Used in industrial boilers for power generation, chemical plants, and refineries.
