PRODUCT INTRODUCTION
310S is a low-cost high-temperature resistant stainless steel material, domestic brand 2520. The maximum service temperature of the material can reach 1200 ℃, and the continuous service temperature is 1150 ℃. It is the first choice of metal materials with low corrosion environment and high temperature resistance in the chemical industry. It is widely used in boilers, chemical heaters, heat pipes and so on. On the basis of 310, 310S reduces the content of carbon and sulfur, reduces the possibility of embrittlement of materials in high-temperature service environment, and avoids excessive secondary cementite and σ Phase.
