The Difference Between 304 and 316 Stainless Steel
304 and 316 are the two most widely used austenitic stainless steel grades globally and are commonly adopted across numerous industries due to their stable performance and manageable costs. This article provides a systematic comparison of these two grades across four dimensions—chemical composition, mechanical properties, corrosion resistance, and application scenarios—to serve as a basis for accurate material selection.

What Is Bulb Flat Bar?
Bulb flat bar is widely used in ship hull frames, deck stiffeners, offshore wind turbine support structures, offshore platform components, and industrial building structural frames. Its unique cross-sectional geometry makes it the preferred stiffening profile in marine engineering, offering superior performance compared to ordinary flat steel and other traditional steel sections.
