Effect of P content fluctuation on mechanical properties of sa573 gr 58 hot rolled carbon steel sheet

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of sa573 gr 58 hot rolled carbon steel sheet etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in sa573 gr 58 hot rolled carbon steel sheet etc. steel is strictly controlled.

SS400 is a low carbon steel with no specified carbon content. According to its mechanical properties, it is similar to sa573 gr 58 hot rolled carbon steel sheet 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. sa573 gr 58 hot rolled carbon steel sheet Standard: JIS G3101-2004. Technology: hot rolled. Type: equal & unequal. Surface: black or galvanized.

Unequal angle: Size: 30 × 20 mm to 250 × 90 mm. sa573 gr 58 hot rolled carbon steel sheet Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.

Safety awareness is the basic understanding and thinking of safety in people's mind, which directly affects people's behavior and habits. In the report of the 19th National Congress of the Communist Party of China, General Secretary Xi clearly pointed out: Establish the concept of safe development and promote the idea of life first and safety first. Therefore, improving employees' safety awareness is an important way for steel companies to strengthen safety management. First, there must be a correct understanding. Ensuring personal safety is not only to ensure safe production, improve corporate efficiency, and promote corporate development, but also to be responsible to relatives, to the family, and most importantly to oneself.
