Leave a message
Due to the higher percentage of chromium and nickel, it has much better creep strength, can operate continuously at high temperatures, and has good high temperature resistance



What are the purposes?
Stamping molds, fixtures, tools, gauges, paper cutters, auxiliary tools, etc
What are the traits?
Improve the brittle properties of carbon tool steel to extend the lifespan of the tool. Vacuum degassing refined steel with stable quality. Good hardenability, oil cold hardening (less cracking and deformation), good toughness and wear resistance, and durable tools.
What is the difference between 310 and 310S?
Grade 310 is a medium carbon austenitic stainless steel suitable for high-temperature applications such as furnace parts and heat treatment equipment.. The 310S level is a low-carbon version of the 310 level.
What does S represent in 310S?
SAE 310S stainless steel is a low-carbon version of 310 and is recommended for applications that may experience sensitization and subsequent corrosion issues from high-temperature gases or condensates during downtime.
310 stainless steel magnetic?
If it has an austenitic structure, then it has no magnetism. In other words, ferritic stainless steel has magnetism, such as grades 409, 430, and 439. Martensitic stainless steels of grades 410, 420, and 440 also exhibit magnetism. Austenitic steel grades are non-magnetic, such as 3.3, 304, 310, and 321 grades.
