Provides users with structured, comprehensive knowledge about steel: from basic classifications, processing techniques, and material testing to engineering selection, procurement and acceptance, and international trade terminology-all content is tailored to the industry's real-world needs.
304 is a general-purpose austenitic stainless steel (18% chromium + 8% nickel); 316 is made by adding 2% to 3% molybdenum to 304, which significantly improves its resistance to chloride ion corrosion.
Q235 is a mild carbon structural steel (yield strength ≥ 235 MPa), while Q355 is a low-alloy high-strength steel (yield strength ≥ 355 MPa). This article compares the differences between the two in terms of chemical composition, mechanical properties, and weldability, and analyzes their respective applications and material selection principles to help you make the right material selection decision.
