Steels of different strength grades can adapt to different load-bearing requirements. S235JR is suitable for structural parts with low load-bearing requirements, S275JR is suitable for structural parts with medium load-bearing requirements, and S355JR is suitable for structural parts with high load-bearing requirements. Users can choose according to specific project requirements.
S235 is a common structural steel in the European standard EN10025. Its strength is about two-thirds of that of ordinary carbon steel and its density is about 7.85 g/cm3. Due to its moderate strength, it can better balance performance and cost in various projects and is a cost-effective steel.
Multi-type production adaptation: It can be applied to various models such as Morgan, Danieli, Pomini, and SMS, with performance and life better than the original equipment manufacturers, and can meet the needs of different production equipment1. High reference value of advanced technology: The development of low-temperature rolling technology for bars and wires provides a useful reference for further application of low-temperature rolling technology in domestic bar and wire production, which helps to optimize the production process
It is mainly composed of iron (Fe) and a small amount of carbon (C), manganese (Mn), sulfur (S), phosphorus (P) and other elements. Strength and elongation characteristics: The tensile strength is about 300MPa, which is a relatively low-strength steel bar, but the elongation is large, and the design strength value is generally 270N/mm². Easy to identify by appearance: As a hot-rolled round grade one steel bar, it is easy to identify at the construction site due to its round appearance.
This type of steel may have good mechanical properties and processing properties. For example, they are used in a variety of processing forms such as forging, bars, and plates, which shows that the material has strong plasticity and can adapt to different processing requirements.
This type of steel usually has higher strength and can withstand greater tension and pressure, making it suitable for applications with higher strength requirements.
