ASTM A335 Q195 is a specification for cold-drawn seamless ferritic alloy steel pipes intended for high-temperature service. This standard covers various grades of alloy steel pipe, including Q195, and provides guidelines for their chemical composition, mechanical properties, and recommended applications.
The ASTM A335 Q195 standard specifies the requirements for seamless ferritic alloy steel pipes. These pipes are designed to withstand high-temperature environments and are commonly used in industries such as petrochemical, power generation, and refineries. The material composition and mechanical properties are critical aspects of this specification to ensure proper performance under elevated temperatures.
The chemical composition of ASTM A335 Q195 is as follows:
| Element | Composition (% by weight) |
|---|---|
| Carbon (C) | 0.06 - 0.15 |
| Silicon (Si) | 0.30 - 0.50 |
| Manganese (Mn) | 0.30 - 0.60 |
| Phosphorus (P) | 0.035 (max) |
| Sulfur (S) | 0.035 (max) |
| Chromium (Cr) | 0.50 - 0.81 |
| Molybdenum (Mo) | 0.44 - 0.65 |
| Nickel (Ni) | 0.25 (max) |
The mechanical properties of ASTM A335 Q195 alloy steel pipe are essential to ensure its structural integrity and ability to withstand high-temperature conditions. These properties are tested under specific conditions and must conform to the following requirements:
| Property | Minimum Value |
|---|---|
| Tensile Strength | 415 MPa (60,200 psi) |
| Yield Strength | 205 MPa (29,700 psi) |
| Elongation | 30% (in 2 inches) |
| Hardness (HB) | 163 (min) |
The steel grade specified in ASTM A335 Q195 refers to the designation given to this particular type of alloy steel. In this case, "Q195" indicates the grade of the material, and it possesses the chemical composition and mechanical properties outlined in the standard.
ASTM A335 Q195 cold-drawn seamless ferritic alloy steel pipes are well-suited for applications in high-temperature environments. Their excellent mechanical properties and resistance to temperature-induced degradation make them ideal for use in industries where reliable performance at elevated temperatures is crucial. Some common applications include:
