ASTM A105&A105M
The ASTM A105 standard covers seamless carbon steel forged fittings. The different equipment made with this specification are good for the ambient temperature in mind. ASTM A105 Carbon Steel Tee helps to connect water pipes in the middle of water pipes. This tube fitting looks like the letter ‘T’ and its connections are made at 90 degree angles. We are one of the best manufacturers of various types of tees that can be customized as per customer needs. Our SA105 Socket Weld Equal Tee is used in many industries, and we manufacture it according to industry standards with the help of state-of-the-art technologies. We are one of the best manufacturers of ASTM A105 Carbon Steel Socket Weld Tee, used to make small diameter pipe fittings (nominal diameter is less than equivalent NPS 2).
We are a top manufacturer of Carbon Steel A105 Threaded Tee, which is very popular in pipe fittings and is available in various lengths and finishes. In addition, we have a good stock of ASTM A105 Carbon Steel Reducing Tee, which is widely used to reduce ports from one point to another. We also supply and export ASTM A105 CS Forged Tee whose branches are at a 45 degree angle from the pipe. No matter what type of ASTM A105 CS Forged Tee you need, contact us to get the best quality products at the most affordable prices as needed.
1. Chemical Composition Requirements
| Chemical Composition of ASTM A105 | |
|---|---|
| Elements | Composition, % |
| Carbon [C] | ≤0.35 |
| Manganese [Mn] | 0.60-1.05 |
| Phosphorus [P] | ≤0.35 |
| Sulfur [S] | ≤0.40 |
| Silicon [Si] | 0.10-0.35 |
| Copper [Cu] | ≤0.40 |
| Nickel [Ni] | ≤0.40 |
| Chromium [Cr] | ≤0.30 |

| Vanadium [V] | ≤0.08 |
*The sum of Cu, Ni, Cr, Mo and V shall not exceed 1.00%.
*The sum of Cr and Mo shall not exceed 0.32%.
*The carbon equivalent CE=[C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15] shall be no greater than 0.47.
| Tensile Strength min. | Yield Strength min. | Elongation min. | Reduction of Area, min. | Hardness | ||

3. Heat Treatment of ASTM A105
Heat treatment is not a mandatory requirement of ASTM A105 piping components. However, there are some exceptions: ASME B16.5 flanges Class 400, 900, 1500, 2500; Flanges of special design where the design pressure at the design temperature exceeds the pressure-temperature ratings of Class 300; Flanges of special design where the design pressure or temperature are not known; Forged fittings or valve parts which are over 4″ and Class 300.API 602 forged gate valves, body: ASTM A105N, trim: 10#, Class 900.
The typical heat treatment conducted for A105 forgings includes annealing(A), normalizing(A), normalizing and tempering(NT), quenching and tempering(QT). Especially, normalizing at approximate 950°C for 2.5 hours is often required by many clients to eliminate possible internal stress in the forgings. These materials are usually marked as “ASTM A105N”.
