Austenitic steel

TP304 General-purpose stainless steel with good corrosion resistance for most applications. Used for: Bar rails, Boat
railings, Canopy supports, Chemical processing equipment, Chemical tubing, Column covers, Duct works, Feed-water
tubes, Food preparation equipment, Food processing equipment, Heat exchanger tubes, Hypodermic needles,
Ladders, Mechanical & structural components, Pharmaceutical processing equipment, Piping systems, Railings
(architectural), Traffic barriers, Water pipes.
TP304H Higher carbon content than 304L, for increased strength, particularly at elevated temperatures.
TP304L Chemical plant and food processing equipment, where freedom from sensitization is required in plate thicknesses
TP316/316L Used where higher corrosion resistance is required. Boat railings, Canopy supports, Chemical tubing, Column covers,
Duct works, Feed-water tubes, Food preparation equipment, Food processing equipment, Heat exchanger tubes,
Hypodermic needles, Ladders, Mechanical & structural components, Pharmaceutical processing equipment, Piping
systems, Railings, Street (urban) furniture, Textile tubing, Traffic barriers, Water pipes.
TP316H Similar oxidation resistance to TP 316. Main areas of application: Heat exchangers, furnaces, chemical and
petrochemical plant.
TP321 Heat exchanger tubing, Chemical processing tubing, Pressure tank tubing. Suitable for heat resisting applications
to 800°C.
TP321H This is the high carbon version of TP 321 which ensures greater creep resistance. Behaves much the same as TP 321
in oxidation resistance. Main applications: Heat exchangers, furnaces, boilers in chemical and petrochemical plant
TP316Ti A titanium stabilized version of 316 used where good resistance to intergranular corrosion and high temperature
strength is required.
TP317 Chemical processing tubing, Dyeing equipment, Ink manufacturing equipment, Pulp & paper manufacturing
TP347HFG Mainly used for boilers in the termal power plant, reheaters and superheaters



Super-Austenitic steel


High resistance to general corrosion in e.g. sulphuric and acetic acids, crevice corrosion, stress corrosion cracking, pitting in chloride bearing solutions.

Ferritic and Martensitic Steel


TP405 Used for applications where hardening upon cooling from high temperatures must be avoided. Has excellent
long-time stability up to 1200°F.
TP410 General purpose grade for use in mildly corrosive environments
TP430 Mechanical & structural tubing, Architectural tubing, Heat exchanger tubing, Condensers, Re-heaters, Evaporators.



S31803 Typically used in heat exchangers, gas scrubbers, fans, chemical tanks, flowlines, marine and refinery applications.
S32750 Used in oil & gas, chemical process, power industries. At that heat-exchangers are main application.
S31254 With high levels of chromium, molybdenum, and nitrogen is especially suited for high-chloride environments such as brackish water, seawater and other high-chloride process streams.

Value-added services
Beveling Stainless Steel tubes contain one end angled,  so that it mates with a complementary tube end. Tubes can be beveled for certain applications in order to make welding of stainless steel tubes easier, which saves weld prep time and money compared to hand cutting.

Ruixiang Steel can heat treat some 400 series stainless steel seamless tube. Heat treating realizes stress as a result of hardening, depending upon the chemistry of the metal being treated. Heat treating is also used for tempering, quenching, normalizing, and solution annealing.

During the honing/turning process, an abrasive rotating tool removes metal from the interior surface of a cylinder, pipe, or tube. The main purpose of honing is to finish the surface to a particular diameter and/or desired cylindrical geometric design. Honing is typically a secondary machining operation that completes a produce/part,  relieves stress created during production, or corrects features of the finished product. A typical production cycle is to drill, ream, heat treat, then hone.
