SA-516 Gr.70 & SA-516 Gr.60 Carbon Steel Dished Heads Manufacturer
What is the Dirrerence bewteen SA-516 Gr.70 Dished Heads and SA-516 Gr.60 Dished Heads?
Carbon Steel with ASME Standards SA-516 Mainly Used for Pressure Vessels and Boilers. and Carbon Steel Dished Heads from Our Factory--Henan Guojiang Precision Formed Head Co., Ltd with Raw Materials of SA-516 Carbon Steel. and with Manufacturing Production Standards of SAME.
1. SA-516 Gr.70
Mechanical Properties:
Tensile Strength: 485–620 MPa;
Yield Strength ≥ 260 MPa
Advantages of SA-516 Gr.70 Carbon Steels:
(1). with High Strength, Under Same Pressure Requirements, The Carbon Steel could choose more thin one, to Reduce the Equipments Total Weights, and Reduce the Production Cost.
(2). It Features Favorable Impact Toughness and Outstanding Low-temperature Properties, and Charpy V-notch Impact Tests are Available Down to -40℃ and Even -46℃.
(3). Good Weldability. HIC Resistance is Available for wet H₂S sour Service Conditions in Oil & Gas Projects.
(4). It is the Most Widely Recognized Carbon Steel Vessel Plate for Global Oil, Chemical and Boiler Industries, and Commonly Used for ASME VIII Projects.
(5). Applications: Dished Heads, High Pressure Vessels, High Pressure Boiler, Reactor, Storage Tanks, etc.
2. SA-516 Gr.60
Mechanical Properties:
Tensile Strength: 415-550 MPa;
Yield Strength ≥ 220 MPa
Advantages of SA-516 Gr.60 Carbon Steels:
(1). Superior Ductility and Elongation, Better Cold Formability, Less Difficulty for Shipping/Stamping of Heads.
(2). Lower Carbon Equivalent, Easier Welding, Lower Welding Preheat Requirement and Reduced Risk of Welding Cracks.
(3). Cost-Effective, Suitable for Medium & Low Pressure Projects. It also Features Good Low-Temperature Impack Toughness and Can Be Supplied with Low-Temperature Impact Tests.
(4). Applications: Dished Heads, Lower Pressure Boilers, Medium & Lower Pressure Heat Exchangers, General Chemical Atmospheric/Medium-Low Pressure Storage Tanks and Surge Vessels. and Pressure Vessels with Low Working Pressure and Complex Forming Profiles, Where Cold Workability is the Primary Consideration Low-Pressure Pressurized Equipment for Non-Acidic Media Under Steady Loas Conditions.
