GH3030 N06075 2.4630 Seamless Tube

Temperature Adaptability: Long-term service at ≤800℃ (sustains thermal strength) and short-term oxidation resistance up to 1100℃ (for low-load components). At 700℃, its 1000-hour creep strength reaches 180MPa, meeting aerospace component requirements. Mechanical Properties: After solution treatment, tensile strength ≥550MPa, yield strength ≥350MPa, and elongation ≥15%. Hardness ranges from 190–250 HB, balancing strength and toughness. Structural Stability: Forms single-phase austenite after solution treatment; only trace Cr₇C₃ precipitates during long-term aging at 700–800℃, with negligible impact on performance. Processing Performance: Excellent weldability (argon arc, spot welding compatible) and cold stamping capability; can be welded with 1Cr18Ni9Ti, GH1140 and other alloys without cracking risk.
