Product Description
The GB/T 32957 standard specifies cold-rolled precision inside diameter seamless steel tubes for hydraulic and pneumatic system service. These tubes are made from high-quality steel that ensures their strength and durability.
The specification outlined in GB/T 32957 provides detailed guidelines and requirements for the manufacturing of precision inside diameter seamless steel tubes. It covers various aspects such as dimensions, tolerance, surface quality, and technical delivery conditions. Adhering to these specifications ensures the consistency and reliability of the steel tubes.
The cold-rolled precision inside diameter seamless steel tubes defined by GB/T 32957 possess several key features that make them suitable for hydraulic and pneumatic system service applications. These features include:
Precision: The tubes are manufactured with high precision, ensuring accurate dimensions and consistent performance.
Seamless Design: Cold-rolled without any welding, these seamless steel tubes have a smooth inner surface, facilitating the fluid flow and minimizing pressure losses.
Strength and Durability: The high-quality steel used in the manufacturing process imparts excellent strength and durability to the tubes, enabling them to withstand high pressures and harsh operating conditions.
Satisfactory Surface Finish: GB/T 32957 defines stringent requirements for the surface quality of the tubes, ensuring smoothness and absence of defects.
The chemical composition of the cold-rolled precision inside diameter seamless steel tubes in accordance with GB/T 32957 is as follows:
| Element | Composition Range |
|---|---|
| Carbon (C) | 0.25% max |
| Silicon (Si) | 0.50% max |
| Manganese (Mn) | 1.20% max |
| Phosphorus (P) | 0.020% max |
| Sulfur (S) | 0.010% max |
| Chromium (Cr) | 0.30% max |
| Nickel (Ni) | 0.30% max |
| Copper (Cu) | 0.25% max |
| Molybdenum (Mo) | 0.08% max |
The mechanical properties of the cold-rolled precision inside diameter seamless steel tubes as specified by GB/T 32957 are as follows:
| Property | Minimum Values |
|---|---|
| Tensile Strength (MPa) | 590 |
| Yield Strength (MPa) | 335 |
| Elongation (%) | 22 |
| Hardness (HB) | 170 |
The steel grade compliant with GB/T 32957 for cold-rolled precision inside diameter seamless steel tubes is designated as SPCD.
The cold-rolled precision inside diameter seamless steel tubes defined by GB/T 32957 are primarily used in hydraulic and pneumatic systems. They are especially suitable for applications where high precision, smooth fluid flow, and reliable performance are required. These tubes find widespread application in industries such as automotive, machinery, and engineering.
While GB/T 32957 standard specifies the SPCD grade for cold-rolled precision inside diameter seamless steel tubes, there may be alternative grades available in the market that offer similar characteristics. It is recommended to consult with steel suppliers or refer to relevant international standards such as ASTM or ISO for alternative grades suitable for specific application requirements.
