Cold rolled key stock specs for precise shaft-hub fits: tolerances, strength, sizes, and grade selection for industrial drives.

Cold rolled steel offers higher strength and precision, while hot rolled steel provides better formability for fabrication.

Among a wide range of metallic materials, austenitic stainless steels stand out for their excellent corrosion resistance, machinability and aesthetics, and play an important role in industry and everyday life.

In daily life, stainless steel is widely used in various products and buildings for its corrosion resistance, ease of cleaning, and aesthetic appeal. However, you may have heard that the surface of stainless steel sometimes turns green. What exactly is going on here?

In the world of stainless steels, 304 and 304L are two widely known grades that occupy an important place in many applications due to their excellent corrosion resistance, processability and aesthetics. Although they are very close in chemical composition, the differences between them should not be overlooked.

Alloys are often added to steel to bring out the desired properties. We will look at the difference between 304, 304L, 316 and 316L.
