DIN 17123 specifies the requirements for welded circular fine grain steel tubes used in structural steelwork. These tubes are designed to provide high strength and durability, making them suitable for various construction applications. The standard covers several steel grades, including StE255, StE285, StE355, StE420, and StE460, each offering distinct mechanical properties to cater to different structural needs.
The chemical composition of these steel grades is crucial for their performance. Below is a table presenting the typical chemical composition for each grade:
Element | StE255 | StE285 | StE355 | StE420 | StE460 |
---|---|---|---|---|---|
C | ≤ 0.20% | ≤ 0.20% | ≤ 0.20% | ≤ 0.20% | ≤ 0.20% |
Si | ≤ 0.55% | ≤ 0.55% | ≤ 0.55% | ≤ 0.55% | ≤ 0.55% |
Mn | 1.00-1.60% | 1.00-1.60% | 1.00-1.60% | 1.00-1.60% | 1.00-1.60% |
P | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% |
S | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% | ≤ 0.035% |
The mechanical properties of these steel grades determine their suitability for different structural applications. The table below outlines the typical mechanical properties:
Property | StE255 | StE285 | StE355 | StE420 | StE460 |
---|---|---|---|---|---|
Yield Strength (MPa) | ≥ 255 | ≥ 285 | ≥ 355 | ≥ 420 | ≥ 460 |
Tensile Strength (MPa) | 370-510 | 410-550 | 470-630 | 520-680 | 550-720 |
Elongation (%) | ≥ 20 | ≥ 19 | ≥ 18 | ≥ 17 | ≥ 16 |
The steel grades covered under DIN 17123 are designed to meet various structural requirements:
These steel tubes are widely used in:
Depending on specific requirements, alternative steel grades may be considered:
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.
