Exploring SUS 304L Stainless Steel: Performance and Application Advantages

SUS 304L is an austenitic stainless steel under the Japanese standard system, which is essentially similar to 304L and exerts its performance relying on a specific alloy ratio. The low - carbon design is the key, and the carbon content is strictly controlled, laying the foundation for its performance.

In terms of characteristics, it has outstanding corrosion resistance, with good tolerance to the daily environment and many weak corrosive media. It has low sensitivity to intergranular corrosion and can still maintain stable corrosion resistance after welding. The mechanical properties are balanced, with excellent plasticity and toughness. It can easily realize forming operations such as bending and stretching. It has stable performance at normal and slightly low temperatures and is not prone to embrittlement.

The processing flow starts from steelmaking. High - quality raw materials are selected, and the composition is accurately controlled through electric furnace smelting. Hot rolling makes the steel initially formed and refines the structure. Cold rolling further improves the surface quality and dimensional accuracy. Solution treatment is a key process, which makes the alloy elements fully homogenized and ensures corrosion resistance and mechanical properties. Subsequently, welding, cutting, surface treatment, etc. can be carried out as needed to adapt to different manufacturing requirements.

The application fields focus on scenarios with high requirements for corrosion resistance and hygiene, such as the food and beverage industry (production equipment, storage tanks, ensuring food hygiene and safety), the pharmaceutical industry (clean pipelines, reaction equipment, meeting strict hygiene standards), high - end kitchenware (tableware, stove parts, beautiful and durable), building decoration (outdoor decorative parts, resisting corrosion from wind, sun and rain), etc. It has become a preferred material in the industry with reliable performance.
