Stainless steel is a type of alloy that contains iron, chromium, and other elements. It is known for its corrosion resistance, strength, and durability. One specific type of stainless steel that has gained popularity in various industries is the Stainless Steel 347.

What is Stainless Steel 347?
Stainless Steel 347 Hex Nuts is a modified version of the basic grade 304, with additions of niobium (columbium) and tantalum. It is an austenitic stainless steel that offers improved high-temperature strength and corrosion resistance compared to other types of stainless steel.

Features of Stainless Steel 347 Hex Nut
One key feature of Stainless Steel 347 is its high resistance to intergranular corrosion. This means that it is less susceptible to cracking and damage in environments with high temperatures or exposure to corrosive substances.
Additionally, the addition of niobium and tantalum improves the overall strength of Stainless Steel 347, making it a popular choice for applications requiring high tensile strength.
Stainless Steel 347 also has good forming and welding properties, making it suitable for various manufacturing processes.
