Will stainless steel rust?

Stainless steel is widely praised for its durability and reputation as “stainless”, but many people still wonder: will stainless steel rust? The answer is under certain conditions. While stainless steel is highly resistant to corrosion, it is not completely immune. Why is stainless steel (mostly) rust-resistant? Stainless steel contains at least 10.5% chromium, which reacts with oxygen to form a thin, invisible, passive layer of chromium oxide on its surface. This chromium oxide layer acts as a barrier, blocking moisture and oxygen from reaching the underlying steel. When the steel is scratched, this chromium oxide layer will usually repair itself in an oxygen-rich environment, keeping the metal protected.However, this passive […]

304 vs 316 Stainless Steel: Comprehensive Comparison of Key Differences

304 vs 316 stainless steel Differences

NEWS / wanzhigroup

This article explores the key differences between 304 vs 316 stainless steel to help engineers, purchasers, and consumers make an informed choice. Stainless steel is a cornerstone material of modern manufacturing, with 304 and 316 stainless steel dominating industrial applications. While both are austenitic stainless steels with similar properties, their differences in chemical composition, performance, and cost make them suitable for different uses. 1、Chemical Composition Differences The main difference lies in their alloying elements: 304 stainless steel: Contains 18% chromium and 8% nickel (18/8 grade) and no molybdenum. This composition provides strong corrosion resistance in mild environments. 316 stainless steel: Adds 2-3% molybdenum to enhance resistance to chloride-induced corrosion (such
