The GB/T 3090 standard specifies the requirements for small diameter seamless stainless steel tubes, particularly those used in medical applications. These tubes are designed to meet stringent standards for cleanliness, corrosion resistance, and mechanical properties, making them suitable for various medical devices and equipment.
The seamless stainless steel tubes covered under this standard are characterized by their small diameter and high precision. They are typically produced through a seamless manufacturing process, ensuring uniformity and integrity throughout the tube's length.
The following table presents the typical chemical composition of the specified steel grades:
| Steel Grade | C (%) | Si (%) | Mn (%) | P (%) | S (%) | Cr (%) | Ni (%) | Mo (%) |
|---|---|---|---|---|---|---|---|---|
| S30408 | 0.08 | 0.75 | 2.00 | 0.045 | 0.03 | 18.00 | 8.00 | - |
| S30403 | 0.03 | 0.75 | 2.00 | 0.045 | 0.03 | 18.00 | 8.00 | - |
| S31608 | 0.08 | 0.75 | 2.00 | 0.045 | 0.03 | 16.00 | 10.00 | 2.00 |
| S31603 | 0.03 | 0.75 | 2.00 | 0.045 | 0.03 | 16.00 | 10.00 | 2.00 |
| S32168 | 0.08 | 0.75 | 2.00 | 0.045 | 0.03 | 18.00 | 10.00 | 3.00 |
The mechanical properties of the specified steel grades are summarized in the following table:
| Steel Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| S30408 | ≥ 205 | ≥ 520 | ≥ 40 | ≤ 187 |
| S30403 | ≥ 205 | ≥ 520 | ≥ 40 | ≤ 187 |
| S31608 | ≥ 205 | ≥ 520 | ≥ 40 | ≤ 187 |
| S31603 | ≥ 205 | ≥ 520 | ≥ 40 | ≤ 187 |
| S32168 | ≥ 205 | ≥ 520 | ≥ 40 | ≤ 187 |
