ASTM A268 Stainless Steel Seamless pipe Introduction
ASTM A268/A268M-10 standard specification covers many grades of ferritic and martensitic stainless steel pipes for general corrosion resistance and high temperature applications, including both seamless and welded pipes. It also specifies the technical requirements, test methods, inspection rules and markings, packaging, transportation, storage, etc. of seamless and welded ferritic and martensitic stainless steel pipes.

Advantages of ASTM A268 Stainless steel Seamless Tube
ASTM A268 stainless steel pipes mainly include a series of ferrite and martensitic stainless steel grades, such as TP405, TP410, TP429, TP430, TP443, TP446-1, TP446-2, TP409, TP439, S41500, S44400, S44700, S44635, TP468.
ASTM A268 stainless steel seamless pipes are widely used in fields that require high strength, wear resistance and certain corrosion resistance, and are often used to manufacture various pipelines, valves, containers and other equipment for transporting and storing corrosive media.
ASTM A268 Stainless steel Tube Heat treatment
TP410 quenched and tempered: high-strength mechanical parts (need wear resistance and medium corrosion resistance, such as pump shafts, tools).
TP430 annealed: oxidation-resistant parts (such as heat exchangers, furnace accessories), no high strength is required, and formability and cost are prioritized.
TP431 medium-temperature tempered: marine environment parts (Ni improves corrosion resistance, and after tempering, balances strength and chloride ion corrosion resistance).
Why Choose GNEE
GNEE provides EN 10204 3.1 material report (including chemical composition and mechanical properties). It can pass CE and ISO 9001 certification, support classification society (ABS/DNV) testing (such as 431 pipes for ship seawater pipelines), conventional specifications are delivered in 7-15 days, and customized orders are 3-4 weeks (small diameter cold-drawn pipes require a longer period).
