What is chemical composition and mechanical properties of S275 material

Our company has S275 material strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply S275 material deep processing service for products S275 material like cutting, drilling, bending, welding and grinding.

Abrasion resistant steel plate has high wear resistance and good impact performance. S275 material, Abrasion resistant steel plate can be cut, bent and welded. Abrasion resistant steel plate can be connected with other structures by welding, plug welding and bolt connection. It is time-saving and convenient in the maintenance process. Abrasion resistant steel plate is widely used in metallurgy, coal, cement, power, glass, mining, building materials, brick and tile industries. S275 material, Abrasion resistant steel plate has a very high cost performance, and has been favored by more and more industries and users.

Because S275 material, boiler steel plate is a product of important use, the safety and reliability requirements are strict, and the manufacturing technology is difficult. The boiler steel plate material must have the following main characteristics:The boiler steel plate has high yield strength performance in a certain temperature range (medium temperature and high temperature);The boiler steel plate has sufficient toughness, no brittle failure accident will occur during manufacturing or use.

Phosphorus is a very harmful element in S275 material steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of S275 material steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

S275 material, Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.

our company is leading supplier of API 5CT casing pipes in China. N80 oil casing pipes enjoy high size precision, good weld toughness, S275 material good extrusion resistance, easy quality control and low cost features. Welcome to our company to purchase S275 material API 5CT N80 and so on casing pipes.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards.
