Forgings like the ASTM A694 F70 Flanges are designed in accordance with the applicable standards, which in this case is specification ASTM A694 as well as standard ASME B16.11 in order to maximize their strength. This, in turn, ensures that the ASTM A694 F70 Steel Blind Flanges will deliver high performance in some of the most demanding industries, particularly those involved in the transmission and of media from refineries to sites. The minimum yield strength at 0.2% offset of the Carbon Steel A694 F70 Material is 70 KSI. A higher yield strength would mean that the material is tougher, thus, making the ASME B16.11 A694 Gr F70 Elbow well suited for applications involving the petroleum industry, which deals with the high pressure transmission of oil, gas or steam across.
ASTM A694 F70 Flanges
Carbon Steel A694 F70 Material
SA 694 F70 Forged Fittings
Carbon steel or alloy steel specified ASTM A694 components are often selected for their high yield capabilities in combination with its excellent toughness and weldability at low temperature.
These high yield SA 694 F70 Forged Fittings not only perform well under high pressure, but the cost of production is much lower than stainless steel alloys or alloy steel grades, due to carbon steels using only 2 alloys. Overall, the excellent performance, along with good strength and toughness and cost is what makes the ASTM A694 Gr F70 Forged Flanges very attractive to many buyers across different industries.
