Product Introduction

Features of 304L Stainless Steel plate

Low Carbon Variant

304L is a variant of 304 stainless steel with reduced carbon content, designed for applications requiring welding. The lower carbon content minimizes carbide precipitation in the heat-affected zone (HAZ) during welding, reducing the risk of intergranular corrosion (also known as weld decay) in specific environments.

Corrosion Resistance

Under normal conditions, 304L offers corrosion resistance similar to that of standard 304 stainless steel. However, after welding or exposure to stress, 304L demonstrates superior resistance to intergranular corrosion. It also maintains excellent corrosion resistance without the need for heat treatment and is generally used at temperatures below 400°C. Additionally, it is non-magnetic and operates effectively within a temperature range of -196°C to 800°C.

surface finish

304L stainless steel plates can achieve diverse appearances and performance characteristics through various surface treatment methods, such as:

NO.1 Surface: Annealed and descaled after hot rolling.
NO.2B Surface: Features a stronger gloss compared to NO.2D and is lightly cold-rolled using polishing rollers.
BA Surface: Ground and polished for a highly reflective finish.

Welding Performance and Corrosion Resistance

Welding Performance

304L stainless steel plates offer excellent welding performance and are suitable for various melting and resistance welding processes. The lower carbon content minimizes the risk of intergranular corrosion during welding, ensuring that the welded material maintains excellent corrosion resistance.

Corrosion Resistance

304L stainless steel exhibits strong corrosion resistance in a wide range of media, including acidic and alkaline gases and solutions. Its corrosion resistance surpasses that of many other materials, allowing it to perform reliably in harsh environments over extended periods without corroding.
