ASTM A314 Grade 310S Introduce
ASTM A314 Grade 310S is a non-magnetic steel grade which offers exceptional strength, formability, weldability, and good toughness. This steel grade is especially suitable for application requiring superior mechanical properties such as manufacturing fuel tanks, pressure vessels and pressure piping. The grade is also highly corrosion resistant to a wide range of solutions and chemicals as well as providing superior oxidation resistance. The mechanical properties of ASTM A314 Grade 310S make it a versatile and valuable choice for the fabrication of structural components and support. This steel grade is capable of providing exceptional strength with low weight, while also providing good resistance to stress corrosion cracking and other forms of attack. The steel also has high tensile and yield strength, allowing engineers and manufacturers the flexibility to fabricate components with complex shapes, thinner walls, and higher strength than other materials.
Smelting temperature:1898°C - 1597°C
