304 vs 316 Stainless Steel: Comprehensive Comparison of Key Differences

304 vs 316 stainless steel Differences

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 […]

Carbon Steel and Stainless Steel

NEWS / wanzhigroup

Carbon steel and stainless steel each have their own strengths. Carbon steel, also known as carbon steel, typically has a carbon content range of 0.0218% to 2.11% (mass fraction). When the carbon content exceeds 2.11%, it is generally referred to as cast iron. Stainless steel belongs to alloy steel, and its core alloying element is chromium (Cr, usually ≥ 10.5%). The carbon content of stainless steel ranges from 0.03% to 0.15% (mass fraction), and some ultra-low carbon stainless steels (such as 304L and 316L) even have a carbon content of ≤ 0.03%. Stainless steel, also known as “inox steel” (French “inoxydab” means “non oxidizable”), truly lives up to its name

Some notes on chrome plating process

NEWS / wanzhigroup

Chrome plating process characteristics Chrome plating process is a relatively complex coating compared to other coatings, with the following characteristics: Chromium is easily passivated and is therefore very stable in many media. Car Network Small dumbbells The chrome plating solution uses highly oxidizing chromic anhydride (CrO3) rather than chromium salts. Therefore, during the plating process, external ions need to be added to achieve the chromium deposition process. The cathode polarization process is complex. Experienced chrome plating workers can judge whether the chrome plating is normal by the amount of cathode “flowers”. This “flower” is the hydrogen released from the cathode. The current density used in chrome plating is very high,
