A192 High Pressure Seamless Tubes are low carbon carbon steel with a chemical composition that strictly adheres to ASTM/ASME standards:
Carbon (C): 0.06% ~ 0.18% (to optimize weldability and toughness)
Manganese (Mn): 0.27% ~ 0.63% (to enhance strength and wear resistance)
Silicon (Si): ≤ 0.25% (to enhance the deoxidation ability and material strength)
Phosphorus (P), sulfur (S): ≤ 0.035% (to control impurities and avoid brittle fracture)
Mechanical properties:
Tensile strength ≥ 325MPa, yield strength ≥ 180MPa, elongation ≥ 35% (to meet the stability needs of high-pressure conditions)
Hardness requirements:
Wall thickness ≥ 5.1mm, Brinell hardness ≤ 137HB;
Wall thickness < 5.1mm, Rockwell hardness ≤ 77HRB (to prevent material embrittlement)
A192 high pressure seamless tubes are designed for high-pressure boiler systems, typical application scenarios include:
Key components: heat transfer parts such as heated surface tubes, header boxes, economizers, superheaters, reheaters, etc.
Working condition parameters:
Working pressure ≤ 9.8MPa, working temperature 450℃ ~ 650℃ (adapted to high-temperature and high-pressure environments in electric power, chemical industry, and other fields)
Special requirements: seamless carbon steel boiler and superheater tubes for minimum wall thickness requirements.
