Key Properties:
Composition: ASME SA387 Grade 11 typically contains about 1% chromium and 0.5% molybdenum. This composition provides good strength and resistance to oxidation at high temperatures.
Mechanical Properties:
Yield Strength: Minimum of 205 MPa (30,000 psi)
Tensile Strength: Minimum of 415 MPa (60,000 psi)
Class 2: This classification indicates that the material has undergone additional heat treatment, enhancing its properties compared to Class 1, which may not have the same level of treatment. Class 2 is intended for applications requiring greater performance under higher stress and temperature conditions.
