SAE 304 stainless steel in acidic applications, it is commonly replaced by 316 stainless steel. 304 stainless steel is used for a variety of household and industrial applications such as food handling and processing equipment, screws, machinery parts, and car headers. 304 stainless steel is also used in the architectural field for exterior accents such as water and fire features. It is also a common coil material for vaporizers. They all possess the same nominal chromium and nickel contents and thus possess the same corrosion resistance, ease of fabrication and weldability. The carbon content of 304H (UNS S30409) is restricted to 0.04-0.10%, which provides
Duplex stainless steel are higher. This can be a great advantage when strength is important. This is the case in bridges, pressure vessels or tie bars. Chemicals composition of grades from EN 10088-1 (2014) Standard are given in the table below: Mechanical properties from European Standard EN 10088-3 (2014) (for product thickness below 160mm): <nowiki>*</nowiki>for thickess ≤ 5 mm The minimum yield stress values are about twice as high as those of austenitic stainless steels. Duplex grades are therefore attractive when mechanical properties at room tempearature are important because they allow thinner sections.
