SA387GR22CL1 Steel Plate | ASME SA387 Grade 22 Class 1 Supplier – Gangsteel

Gangsteel is a professional manufacturer and exporter of SA387GR22CL1 Steel Plate (ASME SA387 Grade 22 Class 1). With more than 15 years of focused experience in Cr-Mo alloy steels, we specialize in supplying reliable SA387 Gr22 Class 1 plates for moderate high-temperature service in boilers, pressure vessels, and petrochemical equipment.

 

What Is SA387GR22CL1 Steel Plate?

SA387GR22CL1 is the Class 1 version of 2.25Cr-1Mo alloy steel. The “CL1” designation indicates lower tensile strength requirements compared to Class 2, which delivers better toughness, ductility, and weldability. This makes SA387GR22CL1 especially suitable for large fabricated components that require on-site welding and good impact resistance at moderate temperatures up to 550°C.

 

Chemical Composition (Heat Analysis, %)

All Gangsteel SA387GR22CL1 plates are produced and tested strictly according to ASME SA387 standards, with full heat analysis reports available for every batch.

 

Mechanical Properties (Class 1 – Normalized and Tempered)

  • Tensile Strength: 415–585 MPa
  • Yield Strength: ≥ 205 MPa
  • Elongation in 50 mm: ≥ 22%
  • Reduction of Area: ≥ 40%
