A249 310S Stainless Steel Polished Tube
GNEE specializes in the production of A249 310S stainless steel pipes that meet international specifications, which have excellent mechanical properties and a wide range of applications. Combining the above advantages, we can provide products that best meet customer requirements.
ASTM A249 TP 310S high temperature stainless steel welded pipe is a super alloy austenitic stainless steel for use at high temperatures. The higher Ni and Cr content enables these stainless steels to prevent oxidation during continuous use at high temperatures. And A249 310S condenser tubes have excellent mechanical properties, tensile strength MPa ≥ 515, yield point MPa ≥ 205.
A249 310S polished pipes are more commonly used in mechanical polishing and electrolytic polishing. It is used in high temperature environments such as boilers, superheaters, heat exchangers and condensers.
