310/310S/310H Stainless Steel Seamless Pipes & Tubes

310 stainless steel (UNS S31000) and its derivative grades not only have excellent high temperature performance, but also have good ductility and weldability. The carbon content of 310H (UNS S31009) is limited to the lower limit of the 310 carbon content range, which is a grade suitable for high-temperature applications. 310S (UNS S31008) is used when the application environment temperature range is lower than the so-called "high temperature" and there are moisture corrosives. Compared with 310H, the lower carbon content of 310S does reduce its high temperature strength.

Product Details of 310/310S/310H Seamless Pipes:

Monel Alloy 400 Seamless Pipes & Tubes

Overview of 310/310S/310H Stainless Steel:

310 stainless steel is an austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance. Because of the higher percentage of chromium and nickel, 310s has much better creep strength, can continue to operate at high temperatures, and has good resistance High temperature. 310S stainless steel is a high-alloy stainless steel belonging to the 25Cr-20Ni series with excellent high-temperature oxidation resistance. It is suitable for making various furnace components with a maximum temperature of 1200°C and a continuous use temperature of 1150°C.

The main elements of 310 and 310S are the same; the main difference is the size of the carbon content: the carbon content of 310 is <=0.25%, and the carbon content of 310S is <=0.08%.The S in 310S represents specially treated 310 stainless steel, and its mechanical properties are better than 310 stainless steel. Therefore, the high temperature resistance of 310S stainless steel is higher than 310 stainless steel.

Manufacturing Process of 310/310S/310H Stainless Steel:

①Main production process of hot-rolled seamless steel pipe (△main inspection process): Tube billet preparation and inspection△→tube billet heating→perforation→pipe rolling→steel pipe reheating→fixed (reduced) diameter→heat treatment△→finished pipe straightening→finishing→inspection△(non-destructive, physical and chemical, bench inspection)→into storage ②Main production process of cold-rolled (drawn) seamless steel pipe: Blank preparation → pickling and lubrication → cold rolling (drawing) → heat treatment → straightening → finishing → inspection

The outer diameter of hot-rolled seamless pipe is generally greater than 32mm and the wall thickness is 2.5-200mm. The outer diameter of cold-rolled seamless steel pipe can be up to 6mm and the wall thickness can be up to 0.25mm. Rolling has higher dimensional accuracy than hot rolling.
