Both ASTM A516 Gr.70 and ASTM A105 are steels used for different applications, for pressure vessel and flange fabrication respectively. The price difference between the two can be caused by several factors:
1. Material cost difference
ASTM A516 Gr.70 is usually used to manufacture pressure vessels, and its materials must meet higher requirements, including tensile strength, yield strength, impact toughness, etc. In contrast, ASTM A105 is used to manufacture flanges, which generally have lower material requirements. Therefore, the production cost of ASTM A516 Gr.70 may be higher.
2. Differences in material properties
ASTM A516 Gr.70 materials usually require more engineering processing and handling to meet their application requirements under high pressure and high temperature conditions. This may require more process and material control, further increasing the cost.
3. Market demand and supply
The market demand and supply of different materials will also affect the price. If the demand for ASTM A516 Gr.70 is high and the supply is relatively small, then the price may go up. On the contrary, if the supply of ASTM A105 is sufficient and the demand is less, the price may be lower.
4. Manufacturing complexity
Flanges are generally simpler to manufacture than pressure vessels because they are usually simpler shapes. ASTM A516 Gr.70 material may require more engineering work to meet the needs of pressure vessels of various shapes and sizes.
In summary, the price difference between ASTM A516 Gr.70 and ASTM A105 can be attributed to various factors such as material properties, market demand, availability, and manufacturing complexity. When purchasing, these factors should be weighed based on specific needs and applications to select the right material and consider its price.

Q: What is the difference between SA516 grade 60 and 70?
A: The main difference between the two plates is their minimum yield strength: ASME SA516 Grade 60 Plate has a yield strength of 60,000 PSI (410 MPa), while SA 516 GR. 70 has a yield strength of 70,000 PSI (485 MPa). ASTM A516 Grade 60 Plate, ASTM A516 Grade 70 Plate, ASME SA516 Gr
Q: What is A516 GR 70 steel grade?
A: ASTM A516 Grade 70 is a carbon steel, applicable for low or medium pressure vessel plates. Sa 516 gr 70 carbon steel are also popularly known as ASME SA516-70.
Q: What material is A105?
A: carbon steel material
A105 steel is a most commonly used carbon steel material grade that is used to manufacture forged piping components such as flange and forged fittings of small diameter piping. This carbon steel material grade is used for ambient- and higher-temperature service in pressure systems.
Q: What is the difference between A516 GR 70 and A105?
A: ASTM A516 Gr. 70 is usually used to manufacture pressure vessels, and its materials must meet higher requirements, including tensile strength, yield strength, impact toughness, etc. In contrast, ASTM A105 is used to manufacture flanges, which generally have lower material requirements.
Q: What is carbon steel A105 equivalent to?
A: Carbon steel valves are kept in stock in forged ASTM A105 and it's cast equivalent ASTM/A216-WCB. The European/DIN equivalent is C22. 8 DIN17243 (1.0460). ASTM A216-WCC and LCC is also available ex stock and on an indent basis.
