DIN 17457 specifies the requirements for welded circular steel tubes made from austenitic stainless steel. These tubes are designed for special applications where corrosion resistance, strength, and durability are paramount. This article will delve into the material specifications, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades.
The austenitic stainless steel grades covered under DIN 17457 include:
| Steel Grade | C (%) | Cr (%) | Ni (%) | Mo (%) | Mn (%) | Si (%) | P (%) | S (%) |
|---|---|---|---|---|---|---|---|---|
| 1.4301 | ≤0.07 | 18.0-20.0 | 8.0-10.5 | - | ≤2.0 | ≤1.0 | ≤0.045 | ≤0.03 |
| 1.4306 | ≤0.03 | 18.0-20.0 | 8.0-12.0 | - | ≤2.0 | ≤1.0 | ≤0.045 | ≤0.03 |
| 1.4311 | ≤0.03 | 18.0-20.0 | 8.0-12.0 | - | ≤2.0 | ≤1.0 | ≤0.045 | ≤0.03 |
| 1.4541 | ≤0.08 | 17.0-19.0 | 9.0-12.0 | 2.0-3.0 | ≤2.0 | ≤1.0 | ≤0.045 | ≤0.03 |
| 1.4550 | ≤0.08 | 16.0-18.0 | 10.0-14.0 | 5.0-7.0 | ≤2.0 | ≤1.0 | ≤0.045 | ≤0.03 |
| Steel Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (HB) |
|---|---|---|---|---|
| 1.4301 | ≥210 | 520-720 | ≥40 | ≤187 |
| 1.4306 | ≥220 | 480-650 | ≥40 | ≤187 |
| 1.4311 | ≥250 | 600-800 | ≥30 | ≤187 |
| 1.4541 | ≥220 | 520-720 | ≥40 | ≤187 |
| 1.4550 | ≥220 | 520-720 | ≥40 | ≤187 |
The steel grades specified in DIN 17457 are primarily austenitic stainless steels, known for their excellent corrosion resistance and mechanical properties. The most commonly used grades include:
Welded circular steel tubes made from these austenitic stainless steels are widely used in various industries, including:
While the grades specified in DIN 17457 are widely used, there are alternative grades that may be suitable for specific applications:
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.
