310S 0Cr25Ni20 hot rolled stainless steel plate

Grade 310S is a low carbon version , for high temperature applications such as furnace parts and heat treatment equipment.

Grades 310S S31008

Grade 310S is a low carbon austenitic stainless steel, for high temperature application such as furnace parts and  heat treatment equipment. 

Typical Applications Grade 310S is fuidised bed combustors, kilns, radiant tubes, tube hangers for petroleum refining and steam boilers, coal gasifier internal components, lead pots, thermowells, refractory anchor bolts, burners and combustion chambers, retorts, muffles, annealing covers, saggers, food processing equipment, cryogenic structures.

Descrption This grade contain about 25% chromium and 20% nicel, makeing them highly resistant to oxidation and corrosion. Grade 310S is a lower carbon version, less prone to embrittlement and sensitisation in service.

The high chromium and medium nickel contents make these steels capable for applications in reducing sulphur atmospheres containing H2S. They are widely used in moderately carburising atmospheres, as encountered in petrochemical environments. For more severe carburising atmospheres other heat resisting alloys should be selected.

Corrosion Resistance Grade 310/310S is generally not used for corrosive liquid service, although the high chromium and nickel content give corrosion resistance superior to grade 304. The alloy does not contain molybdenum, so pitting resistance is quite poor. Grade 310/310S will be sensitised to intergranular corrosion after service at temperatures in range 550 - 800oC. Chloride stress corrosion cracking may take place in corrosive liquids containing chlorides at temperaturesexceeding 100oC. Heat Resistance Grades 310/310S have good resistance to oxidation in intermittent service in air up to 1035oC and 1050oC in continuous service. The grades are resistant to oxidation, sulphidation and carburisation.
