SUS304L Stainless steel bar bars

SUS304L stainless steel is a low-carbon variant of 304 stainless steel and is a basic austenitic steel. Its carbon content does not exceed 0.030%. By reducing the carbon content, the precipitation of carbides in the heat-affected zone of welding is effectively reduced, and the risk of intergranular corrosion is significantly reduced. This material has excellent corrosion resistance and heat resistance, and maintains stable mechanical properties in the temperature range of -196℃ to 800℃. It is widely used in metal products, sanitary ware, pressure vessels and chemical industry equipment that need to be welded.

Corrosion resistance
SUS304L is an austenitic stainless steel with a chromium content of 18%-20%, a nickel content of 9%-13%, and a carbon content of ≤0.03%, which effectively reduces the precipitation of carbides in the heat-affected zone of welding and significantly reduces the risk of intergranular corrosion. It maintains stable performance in the temperature range of -196℃ to 800℃, and is especially suitable for chemical equipment, pressure vessels and other scenes with high requirements for corrosion resistance.

Mechanical properties
Tensile strength ≥520MPa, yield strength ≥205MPa, elongation ≥40%, cross-sectional shrinkage ≥60%, hardness ≤187HB. Its single-phase austenite structure is non-magnetic and still maintains good toughness after processing. ‌

Processing characteristics
It can be cold and hot processed, supports complex forming processes such as welding, stamping, and bending, and can form a strong joint without additional welding materials. It still maintains corrosion resistance after welding, which is suitable for manufacturing precision parts and complex structural components. ‌

Application scenarios
Widely used in chemical equipment, petroleum and coal industry equipment, pressure vessels, outdoor decorative materials and food processing equipment, etc., especially recommended for applications that require welding and are sensitive to intergranular corrosion.

Composição do aço inoxidável

O aço é uma liga de ferro e carbono. Os aços inoxidáveis são aços que contêm pelo menos 10,5% de crómio, menos de 1,2% de carbono e outros elementos de liga. A resistência à corrosão do aço inoxidável e

As propriedades mecânicas podem ser melhoradas pela adição de outros elementos, como o níquel, o molibdénio, o titânio, o nióbio, o manganês, etc.
