Tp316l Stainless Steel Tube

astm a312 304l


What is ASTM a312 ?

The pipes are used in the high temperature service . Due to the addition of titanium and molybdenum in the composition, the Stainless Steel Pipe ASTM A312 Tp304 is stronger and is also corrosion resistant. Our ASTM A312 Tp304 Efw pipes are electric fusion welded and are less vulnerable to localized corrosion.

ANSI/ASME B36.10M Welded and seamless wrought steel pipe. Standard Description ASTM A213/A213M Seamless ferritic and austenitic alloy steel boiler, superheater and warmth exchanger . ASTM A249/A249M Welded austenitic steel boiler, superheater, heat exchanger and condenser tubes. ASTM A269 Seamless and welded austenitic stainless steel tubing for basic functions. ASTM A270 Seamless and welded austenitic stainless steel sanitary tubing.

We have thousands tons stock of stainless steel and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.

Characteristics of Stainless Steel Sheet and Plate:
High corrosion resistance
High strength
High toughness and impact resistance
Temperature resistance

Smooth surface finish that can be easily clean

It is an austenitic stainless-steel and has chromium content in it. This makes the ASTM A312 Grade Tp304l corrosion resistant. TheA312 Tp304l Pipecan be produced in several methods and it may come in numerous shapes as nicely. Oshwin Overseas is a large producer and supplier of these pipes and we produce every kind and variations of the product. OurA312 Tp304l Efwpipes are very robust and have lengthy lasting joints due to the electrical fusion weld.

ASTM A790/A790M Seamless and welded ferritic/austenitic stainless steel pipe.


Grade 304/304L is the commonest austenitic chrome steel that suits most corrosive functions. Any different grade within the 300 collection enhances the fundamental options of SS304. They are seen principally in the meals and beverages industry, cryogenic applications, sanitary and containment functions as well. Because of the low content material in theASME SA312 Type 304lis much less sturdy than the ordinary 304 .

ASTM A450/A450M General requirements for carbon, ferritic alloy and austenitic alloy steel tubes. ASTM A530/A530M General requirements for specialised carbon and alloy steel pipe.

It has additionally stronger resistance to seawater corrosion, in comparison with chrome steel 316. Therefore, duplex pipes mix the qualities of ferritic and austenitic chrome steel materials. The ASTM A790 specification covers seamless duplex and duplex pipes for demanding purposes, with excessive corrosion, temperature, and strain.

astm a312 materials

These kinds of stainless steels are magnetic but to a decrease extent than ferritic, martensitic and precipitation hardening grades because of the 50% austenitic content material. The normal chrome steel pipes dimensions are set by the ANSI ASME B36.19 specification. Even if austenitic steels are generally non-magnetic, they can present some magnetic property primarily based on the precise alloy composition and the work hardening given during production. Austenitic stainless steels are divided into the sequence 200 (chromium-manganese-nickel alloys) and 300 (chromium-nickel alloys like 304, 309, 316, 321, 347, and so forth).
