Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between ASTM A514 structural steel material, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.
EN10113 S275M is a technical delivery conditions for thermomechanical rolled weldable fine grain structural steels.S means the structural steel, M means the delivery condition.Capital letter L for the quality with specified minimum values of values of impact energy. ASTM A514 structural steel material. The EN10113 S275M steel is equivalent to DIN StE285TM, UNI FeE275KGTM..
Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the ASTM A514 structural steel material project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of ASTM A514 structural steel material customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
The work performance of ASTM A514 structural steel material etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.
