SS400 is a low carbon steel with no specified carbon content. According to its mechanical properties, it is similar to EN steel S355ML ASTM A36, which is widely used in engineering and industrial applications. The cost of JIS SS400 steel angle steel structure is low, and it has good performance in major projects. SS400 angle steel description:Item: SS400 angle steel. EN steel S355ML Standard: JIS G3101-2004. Technology: hot rolled. Type: equal & unequal. Surface: black or galvanized. Length: 6 m, 9 m, 12 m or per your request. Equal angle: Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 to 20 mm. Length: 6 m, 9 m, 12 m or per your request. Unequal angle: Size: 30 × 20 mm to 250 × 90 mm. EN steel S355ML Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of EN steel S355ML nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of EN steel S355ML steel, can be used as an alloying element of low alloy steel.
According to the economic development trend in Asia and the economic development of China, India, Japan and ASEAN, it is estimated that the steel consumption in Asia will be 1228 million tons in 2019, with a year-on-year growth of 6.6%; the EN steel S355ML steel demand in Asia in 2020 is predicted to be 1.241 billion tons, with a year-on-year growth of 1.1%. According to the EN steel S355ML economic development of Europe, it is estimated that the steel consumption in Europe will be 202 million tons in 2019, with a year-on-year decrease of 3.3%; the steel demand in Europe in 2020 is predicted to be 205 million tons, with a year-on-year growth of 1.5%.
