Specs Characteristics Applications
309S Type 309S stainless steel is a low carbon version of Type 309. Because of its lower carbon-content, Type 309S minimizes carbide precipitation, and improves weldability. Other key properties of Type 309S :
•It can be easily roll formed, stamped and drawn
•Higher resistance to marine atmospheres than Type 304
•Good weldability and machinability
•Outstanding resistance to oxidation
Aviation heater, incinerator, auto heat treatment, heat exchanger
310S Type 310S is a low carbon austenitic stainless steel. Known for its ability to withstand high temperature applications, Type 310S, which is a lower carbon version of Type 310, also offers such as :
•Outstanding corrosion resistance
•Good aqueous corrosion resistance
•Not prone to thermal fatigue and cyclic heating
•Superior to Type 304 and 309 in any environments
•Good strength in temperatures up to 2100°F
Heat exchanger, Exhaust device, jet engine, gas turbine parts
253MA 253 MA is perfectly suitable for an environment where highly requiring heat resistant with high strength and maintaining a good oxidation resistance. It is also cost effective and stable due to its lean 11% nickel content of RA 253 MA. it performs well at temperatures up to 2000°F (1093°C), similar to 310 stainless steel. Iron manufacturing, non-ferrous metal industry, power generation facility (energy conversion plant), cement industry, heat exchanger, incinerator
