S355JR low alloy high strength steel plate
S355JR low alloy high strength steel plate Detailed introduction
S355JR is a commonly used structural steel material, and its implementation standard is EN10025-2. This standard includes the chemical composition, mechanical properties, physical properties, processing properties and other aspects of the steel requirements. Among them, the chemical composition requires that the steel contains a certain proportion of carbon, silicon, manganese, phosphorus and sulfur and other elements, the proportion and content of these elements have an important impact on the performance of the steel.
S355JR Mechanical properties
The mechanical properties require S355JR steel to have certain strength, toughness and tensile properties, which are key indicators when the steel is used. Physical properties require steel to have certain corrosion resistance and wear resistance, and these performance indicators determine the service life of steel. Machinability requires that steel is easily machined into various shapes and sizes, which is an important performance indicator in steel manufacturing, processing and application. Therefore, the requirements for S355JR steel in the EN10025-2 standard are very strict, which also ensures that S355JR steel can meet the needs of various applications.
S355JR is a low-carbon structural steel, its main features are as follows
1. High strength: The yield strength of S355JR reaches 355MPa, with high tensile strength and yield ratio, which can meet the needs of various high-strength structural parts.
