What is the grade equivalent of P265GH?
1. Correspondence of domestic standards
GB/T 713.2 standard: P265GH is close to Chinese grade Q265R in chemical composition and mechanical properties, and the yield strength is 265MPa. The yield strength is 265MPa, which is suitable for the manufacture of pressure vessels and medium and low pressure boilers.
2. Expansion of international standards
ASTM/ASME standard: approximate to SA-516 Gr.60 (yield strength 220MPa), need to adjust according to the actual working conditions. The heat treatment process should be adjusted according to the actual working conditions to match the performance.
3. Chemical composition and properties
Carbon (C): ≤ 0.20%, manganese (Mn): ≤ 1.60%, phosphorus / sulfur (P / S): ≤ 0.025%, to protect the weldability and low-temperature toughness Impact performance: Normal temperature impact function: ≤0.025%;
Impact performance: room temperature impact work ≥40J, to meet the general industrial equipment pressure requirements.
4. Application Scene
Mainly used in petrochemical tanks, heat exchangers and non-high-temperature pro-hydrogen equipment, taking into account the balance between cost and performance.
Summary of P265GH
The domestic equivalent material of P265GH is Q265R (GB/T 713.2), and the international approximate standard is SA-516 Gr.60, which is highly compatible in strength and application fields. Specific material selection should be combined with design specifications and service environment verification.
