AISI A312 tube wildely used in Neutral salt pot electrodes,Oil burner parts and Boiler baffles, we have been trial production of such tubes in OD34XWT3.5mm last month,
please check detail EN 1.4763 and S44600 inspection pictures and technical data as below.

446 is a high chromium ferritic heat resistant alloy with excellent resistance to oxidation, sulfidation and other forms of hot corrosion. This grade is most commonly used between 1500 - 2100°F, although its elevated temperature strength is quite low. 446 is the only heat resistant alloy that will tolerate molten copper and brass. As with other high chromium ferritic stainless, 446 embrittles severely in the 700-1000°F temperature range (885°F embrittlement). 446 should not be used in this temperature range unless nearly complete loss of room temperature ductility may be tolerated. Sigma phase embrittlement occurs upon long time exposure in the 1000-1300°F range.
