The Cold Work Hardening Of AISI 347
AISI 347 is a grade of stainless steel known for its properties that make it suitable for cold work hardening. As a common ferritic grade of stainless steel, AISI 347 has a low carbon level, giving it good weldability and hot-working properties and also moderate cold-working characteristics. It contains niobium for superior scaling and intergranular corrosion resistance. This grade of stainless steel has a high melting point and very good stability in corrosive media, making it highly useful in a wide range of applications where the highest level of toughness and strength is important.
The cold work hardening of AISI 347 is the process of using cold working methods such as cold rolling and cold drawing to temper AISI 347 so as to improve its properties. Cold work hardening is a process whereby the material gets more resistant to mechanical impacts and other materials. Cold work hardening of AISI 347 stainless steel increases the tensile strength, yield strength, formability, and elongation of the metal.
AISI 347 stainless steel is one of the most commonly used grades for cold work hardening. This grade of stainless steel is easy to work, making it suitable for a wide range of applications in cold working and welding applications. The alloy’s range of mechanical properties makes it a desired choice for making a wide array of components that are subjected to both low and high temperatures. The low carbon content of AISI 347 stainless steel gives it increased weldability and good formability.
When looking to cold work harden AISI 347 stainless steel, here are some of the key characteristics to keep in mind:
• Cold work hardening rate is lower than of the austenitic grades such as 304 and 316, making it suitable for more sophisticated shaping processes.
• The alloy offers good levels of strength, though it cannot be worked as much as more malleable austenitic grades.
• AISI 347 has better hot corrosion resistance than austenitic grades and provides superior corrosion resistance in acidic and alkaline media.
• Modified grades exist with further enhancements of mechanical properties, corrosion resistance, and weldability.
As with any cold work hardening process, it is important to carefully monitor the temperature, pressure, and the attributes of the material so as to ensure that the desired properties are achieved. AISI 347 stainless steel is a versatile and reliable grade for use in cold work hardening to give structural components for general purpose applications. When looking for a suitable material for cold work hardening, look no further than AISI347.
