310S Stainless Steel Coil

310S stainless steel coil is austenitic chromium-nickel stainless steel with good oxidation resistance and resistance, corrosion and high temperature resistance.

Because of the higher percentage of chromium and nickel, it has much better strength, can work continuously at high temperature, and has good high temperature resistance.

The mechanical properties of 310S are superior compared with 304/304L. It also has improved ductility and toughness due to the addition of molybdenum, nickel and manganese. The thermal conductivity of 310S is lower than that of 304/304L due to the addition of molybdenum which slows down the rate at which heat is lost from the surface when compared with 304/304L.


The addition of these elements results in improvements in strength and hardness, as well as resistance to intergranular corrosion (IGC). Due to its high chromium content, it has good resistance to general corrosion and pitting. This means that it is suitable for use in many applications such as chemical plants and marine environments where there are aggressive chemicals present. The alloy also exhibits excellent resistance to chloride stress cracking (SSC).


Properties of Stainless steel 310/310S
An austenitic heat resistant alloy with excellent resistance to oxidation under mildly cyclic conditions through 2000ºF. Its high chromium and nickel contents provide comparable corrosion resistance, superior resistance to oxidation and the retention of a larger fraction of room temperature strength than the common austenitic alloys like Type 304. Stainless 310 is often used at cryogenic temperatures, with excellent toughness to -450°F, and low magnetic permeability.

As you can see below, Grade 310S is a low carbon version of grade 310. 310S is less prone to embrittlement and sensitization in service.
