| High Light | Industry Stainless Steel Needle Tubing ，ASTM A908 Stainless Steel Needle Tubing ，304 Austenitic Stainless Steel Needle Tubing | ||
Austenitic stainless steel needle tubing is widely used in various industrial applications due to its excellent corrosion resistance, high strength, and good formability. The ASTM A908 specification covers the requirements for stainless steel tubes made from grades 304, 304L, 316, and 316L. This article delves into the material specifications, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades.
The ASTM A908 standard specifies the requirements for austenitic stainless steel needle tubing, which is characterized by its high-quality finish and precise dimensions. These tubes are often used in applications requiring high cleanliness and resistance to corrosion.
The following table presents the chemical composition of the stainless steel grades covered under ASTM A908:
| Grade | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Chromium (Cr) | Nickel (Ni) | Molybdenum (Mo) |
|---|---|---|---|---|---|---|---|
| 304 | ≤ 0.08% | 2.00% max | 0.045% max | 0.030% max | 18.0-20.0% | 8.0-10.5% | - |
| 304L | ≤ 0.03% | 2.00% max | 0.045% max | 0.030% max | 18.0-20.0% | 8.0-12.0% | - |
| 316 | ≤ 0.08% | 2.00% max | 0.045% max | 0.030% max | 16.0-18.0% | 10.0-14.0% | 2.0-3.0% |
| 316L | ≤ 0.03% | 2.00% max | 0.045% max | 0.030% max | 16.0-18.0% | 10.0-14.0% | 2.0-3.0% |
The following table outlines the mechanical properties of the stainless steel grades specified in ASTM A908:
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (Rockwell B) |
|---|---|---|---|---|
| 304 | 215 | 505-720 | 40 | 70-90 |
| 304L | 200 | 485-620 | 40 | 70-90 |
| 316 | 290 | 580-720 | 40 | 70-90 |
| 316L | 220 | 480-620 | 40 | 70-90 |
The primary steel grades covered under ASTM A908 are:
Austenitic stainless steel needle tubing is used in various applications, including:
While ASTM A908 grades are widely used, there are alternative grades that may be considered based on specific application requirements:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
