Features of Stainless Steel 347 screws

347 Stainless Steel screws offer several notable features due to their unique composition and properties which include:

• Columbium Stabilization: SS 347 screws are composed of columbium (niobium) that refines the steel and minimizes the formation of carbide during service at high temperatures.
• Oxidation Resistance: 347 SS screws are very good oxidation resistance, suitable for use in parts that are subjected to high temperature and oxidizing conditions.
• Intergranular Corrosion Resistance: SS 347 screws provide better resistance to intergranular corrosion, which is desirable for the post-welding condition and high-temperature applications.
• Corrosion Resistance: SS 347 screws offer moderate corrosion protection, appropriate for use in moderately corrosive environments.
• Weldability: SS 347 screws ensure excellent weldability, thus a low chance of weld decay due to columbium stabilizing the grain structure.
• Strength: SS 347 screws provide high tensile and yield strength that enables the material to be used in structural applications where strength at high temperatures is desirable.
• Thermal Fatigue Resistance: These screws can resist thermal fatigue, this means that the material is suitable for components that are exposed to cyclic heating and cooling.
• Stress Corrosion Cracking Resistance: Stainless Steel 347 screws offer better resistance to stress corrosion cracking than other stainless steel grades.
• Ductility: SS 347 screws do not easily crack which is helpful especially when installing the wire or in cases when adjustments have to be made.
• Non-Magnetic: SS 347 screws are usually, not magnetic in the annealed state to be suitable for those applications where the magnetic characteristics are undesirable.

These features contribute to the versatility and reliability of Stainless Steel 347 screws in various demanding applications.
