1.4550 / AISI 347 is an austenitic chromium-nickel stainless steel with titanium and niobium addition. Good resistance to intergranular corrosion. 321 Stainless Steel AK SteelSTAINLESS STEEL TYPE 321 is a stabilized austenitic stainless Hardness, B 85 (586) 35 (241) 55 70 CORROSION RESISTANCE AWS E/ER 347 or E/ER 321 is most often specified. Type 321 is well known in reference literature and more information can be obtained in this way.
The 347 stainless steel grade is a stabilized alloy, due to its columbium + tantalum component within. Ideal for long-term work life in high temperatures (800-1500ºF), 347 Stainless Steel is also resistant to intergranular corrosion in the chromium carbide precipitation range. 347 Stainless Steel Plate, Sheet, and Round BarThe 347 stainless steel grade is a stabilized alloy, due to its columbium + tantalum component within. Ideal for long-term work life in high temperatures (800-1500ºF), 347 Stainless Steel is also resistant to intergranular corrosion in the chromium carbide precipitation range. AISI 347/347H - AperamValues according to ASTM A240/A240M standard for AISI 347 General Characteristics Grade 347 from Aperam South America is a stainless steel elaborated to meet the international standards AISI 347 and AISI 347H. Due to the stabilization with niobium, this grade has the corrosion resistance at high temperatures as its main characteristic.
Alloy 347 is a chromium nickel stainless steel which has been modified by the addition of columbium and tantalum. The main advantage of this is an excellent resistance to intergranular corrosion which is common to other austenitic stainless steels following exposure to temperatures of 800° to 1500°F.

ATI 321, ATI 347, and ATI 348 alloys are stabilized stainless steels which offer as their main advantage an excellent resistance to intergranular corrosion. Aircraft Stainless Steel BS S130 / 2S130D (MSRR)BS S130 is the British aerospace equivalent of stainless steel grade 347, and is often dual-certified to the US aerospace specifcation AMS 5646 and the Rolls Royce specification MSRR 6522. It is generally supplied as bright bar in the finally heat treated and cold drawn/ground condition, designated S130D. Alloy 347 - Stainless steels - NeoNickelAlloy 347 is generally used where corrosive conditions are severe, such as aircraft exhaust stacks, manifolds and ring collectors. Type 347 is also used for heavy welded assemblies which cannot be annealed after welding or where the operating conditions cause exposure within the temperature range between 426.67° to 815.55°F.

Type 347 is a niobium stabilized chromium nickel austenitic stainless steel with corrosion resistance similar to 304/304L. This grade is typically used in the 800-1500F temperature range where it is stabilized against chromium carbide precipitation by the addition of niobium, which results in the precipitation of niobium carbides.
