Advantages
310S (UNS S31008) is the low carbon version of the alloy. It is utilized for ease of fabrication. 310H (UNS S31009) is a high carbon modification developed for enhanced creep resistance. In most instances the grain size and carbon content of the plate can meet both the 310S and 310H requirements.
Alloy 310 can be easily welded and processed by standard shop fabrication practices.
Melting point 1470℃, 800℃ began to soften, allowable stress continued to reduce.
Improve the common carbon tool steels brittle nature, and to extend the life of tools.
Vacuum degassing refining steel, stable quality.
Good hardenability, oil cold hardening (quenching and deformation less) good toughness and wear resistance, durable tools.
