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.
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.

La norma o estándar ASTM A234 es una especificación para los accesorios para tubos de acero que incluyen materiales de carbono y acero aleado para servicios de media y alta temperatura. La materia prima fuente de los accesorios de tubería de acero ASTM A234 WPB puede ser de tubería de acero, como ASTM A106 Gr.B y C.
Vessels are made up of plate materials. A106 is a pipe destination. A105 is a forged material and widely used for flange
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.
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.

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. Reference : the blog : thepipingmart com
