Stainless Steel Guides

304 and 316L are both austenitic stainless steels, but 316L's 2-3% molybdenum makes it far more resistant to chloride pitting (typical PREN ~25 vs ~19). This guide compares composition, corrosion resistance, strength and cost - with an application-by-application table, coastal and high-pollution guidance, and an order checklist.

PVD color consistency is the difference between a facade that reads as one surface and one with visibly mismatched panels. This guide explains why PVD panels vary (substrate roughness, coating drift, batch differences), how ΔE is measured, and how MetalMagus holds color difference to ΔE < 1.0 - measured per batch with a spectrophotometer. Includes supplier questions and FAQ. From MetalMagus (HANDYOU Stainless Steel), 58,000 m2 PVD manufacturer, exporting to 60+ countries since 2001.

A stainless steel surface finish determines how your project looks, how easy it is to clean, how it resists corrosion, and what it costs. This guide compares the six standard finish types - 2B, BA, No. 4, HL, mirror and specialty finishes like PVD and sandblasting - with typical Ra ranges, relative cost tiers and five decision factors. Includes an application-by-application table, QC checklist and FAQ. From MetalMagus (HANDYOU Stainless Steel), exporting to 60+ countries since 2001.
