Difference Between ASTM A105 and A106
Chemical Composition
ASTM A105 and A106 contain similar chemical compositions of carbon, manganese, phosphorus, sulfur, and silicon. However, the percentage of each element is different in A105 and A106 according to their standards.
ASTM A105 is a forged carbon steel with a maximum carbon content of 0.35%, while A106 is a seamless carbon steel pipe with a full carbon content of 0.30%. Hence, the chemical composition gives A105 a slightly higher tensile strength and yield point, whereas A106 offers better flexibility.
Manufacturing Method
ASTM A105 fittings are manufactured by forging, while A106 pipes are produced through a seamless manufacturing process. This means that A106 pipes do not have a welded seam, making them ideal for high-pressure or high-temperature applications where welds can fail.
On the other hand, removing the seam in A106 pipes reduces the wall’s thickness, resulting in a lower tolerance for bending. In comparison, A105 fittings can be bent or forged into complex shapes, making them perfect for manufacturing various industrial fittings.
Temperature Limitations
ASTM A105 provides a reliable source of various temperature ratings with the required reports and testing. It is designed to withstand temperatures from -29°C to 537°C. This characteristic makes ASTM A105 fittings ideal for high-heat applications and industrial settings where components are exposed to high temperatures.
In comparison, ASTM A106 is recommended for temperatures below 450°C because it is less heat-resistant. The maximum operating temperature for A106 pipes is around 425°C.
Cost
Regarding cost, ASTM A105 fittings are generally more expensive than A106 pipes. This is mainly because of its extra strength and stability to withstand higher-pressure systems.
However, the overall cost of your project will depend on various factors, such as manufacturing, transportation, and installation costs, amongst others. Hence, evaluating your industrial project’s requirements is essential before selecting a material.

What is the difference between A105 and A106 gr b?
Vessels are made up of plate materials. A106 is a pipe destination. A105 is a forged material and widely used for flange
What is the difference in a105 and a106 pipes?
Simply, A105 is an ASTM standard for a ratedsteel where SA105 is the ASME standard for (nominally the same) rated steel. Basically, they are the same, although SA105 has additional applications beyond A105 according to ASME standards.
What is defrence between fitting NACE material A105?
NACE MR0175 is a standard for sulfide stress cracking resistance in oil and gas industry equipment. A105 is a common carbon steel material used for flanges and fittings. Fitting NACE material A105 would mean that the A105 material meets the requirements specified in NACE MR0175 for sulfide stress cracking resistance.
What is the difference between ASTM a53 and ASTM a106?
Both A53 and A106 are common for non corrosive services up to about 750 deg. A106 is killed steel (silicon content is present) , thus suitable for some services where Hydrogen present.
Is there any difference between astm a105 and astm a105n?
ASTM A105N is different from A105. The A105 is classed "as forged" as opposed to A105N where the 'N' stands for normalized i.e. it has been heat treated to remove the internal stresses caused by casting, forming etc. If a customer specifically asks for A105N then it will be for a good reason. The normalizing heat treatment will ensure the A105N has superior properties to that of the A105. The 'N' is not a category code, the A105 should be normalized if intended for use below -1 C. There are API regulations that go further into it that you should read up on, primarily API RP14E. Hope this helps
What is the difference between a234 and sa234?
a105 is forged carbon steel fittings and are used in ambient temperature or low temperature service whereas, a234 is wrought carbon steel/low alloy steel fitting used in moderate or elevated temperatures.
Can you use astm a216 instead of astm a105?
yes, we can use A105 instead of WCB. WCB is the casting grade while the A105 is equivalent forged grade.
Can you use astm a216 wcb instead of astm a105?

Can you use astm a105 instead of astm a216 wcb?
yes, we can use A105 instead of WCB. WCB is the casting grade while the A105 is equivalent forged grade.
What is the differences between bs 1387 and astm a53?
For example when we compare between A106-B and A53-B seamless from chemical composition point of view, we find that :1. A106-B contains silicon, min. 0.10% where A53-B has zero%, and silicon is the important element for improving the heat resistance criteria.2. A106-B contains manganese 0.29-1.06%, where A53-B 1.2%.3. A106-B contains low sulfur and phosphorus, max. 0.035%where A53-B contains 0.05 and 0.045%respectively.
