ASTM A213 TP 347, SA 213 TP 347H Stainless Steel is a stabilized stainless steel which offers as its main advantage an excellent resistance to corrosione intergranulare following exposure to temperature in the chromium carbide precipitazione range from 800 to 1500°F (427 to 816°C). SA213 TP347 TP347H is austenitico chromium steel containing columbium stabilized by the addition of columbium and tantalum.

SA213 TP347H Stainless Steel Tubes Character

ASTM A213 TP347 stainless steel tubes is also advantageous for alta temperatura service because of its good proprietà meccaniche. Alloy 347H stainless steel tube offers higher creep and stress rupture properties than Alloy 304 and particularly Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosione are concerned. SA213 TP347H stainless steel pipe has a high resistance to prolonged heat and corrosione making it well suited for engine, power generation, saldato fabrications and other high calore applications. SA213 TP347 stainless steel offers good proprietà meccaniche with higher creep and stress rupture characteristics than other grades, such as 304. 347 stainless steel is also advantageous in applications that require omission of the ricottura process after welding.

347 347H Stainless Steel Tubes are austenitico chromium steels containing columbium. 347 347H Stainless Steel are recommended for parts fabricated by welding which cannot be subsequently annealed. These types also are used for parts which are intermittently heated and cooled to temperatures between 800°F and 1600°F. The addition of columbium produces a stabilized type of stainless that eliminates carbide precipitation, and consequently, corrosione intergranulare.

Che cosa significa la H?

I gradi H hanno un contenuto di carbonio compreso tra 0,04 e 0,10%. I gradi H hanno una maggiore resistenza alla trazione e allo snervamento. I gradi H hanno spesso una resistenza alla trazione e allo snervamento minima leggermente superiore (in genere 30MPa in meno) rispetto agli acciai inossidabili standard.

SA213 TP347 TP347H Stainless Steel Design Features

• Superior general resistenza alla corrosione over Type 321 due to stabilization with columbium.
• Reduced tendencies to form continuous networks of chromium carbides at the grain boundaries.
• Better high temperature properties than 304 or 304L. Generally used for parts which are intermittently heated up to 1500 °F. For continuous service the maximum temperature is 1650°F.
• Type 347H has high carbon (0.04 – 0.10) for better alta temperatura creep properties.
• Improved corrosione intergranulare resistenza.

Benefits of 347 SA213 TP347H Stainless Steel

• Higher creep stress and rupture properties when compared with 304
• Ideal for high temperature service
• Overcomes sensitization and intergranular corrosion concerns
• Can be used in elevated temperature applications for ASME Boiler and Pressure Vessel Code applications
• Due to stabilisation the material offers better overall corrosion resistance when compared to 304/304L
• Excellent mechanical properties
• A high carbon version (347H) is also available

SA213 TP347 / TP347H Stainless Steel Heat Treatment

Annealing:Heat to 1850/2000°F (1010/1093°C) and quench in water. Brinell hardness approximately 150.

Hardening:Cannot be hardened by heat treatment, it can only be hardened through cold working.

Stabilizing:If temperature during use is expected up to 1600°C stabilizing between 1550/1650°F (843/899°C) can be used for optimum corrosione intergranulare.

347/347H Stainless Steel Machinability: When machining 347 its chip is tough and stringy, use rigid tooling with heavy cuts to prevent work hardening.
