What is the difference between 304 and 347 stainless steel?

What is the difference between 304 and 347 stainless steel?

Type 347 has excellent intergranular corrosion resistance after exposure to this temperature range, and this grade resists oxidation up to 1500˚F and has higher creep and stress rupture properties than 304/304L. It also possesses good low temperature toughness and is non-magnetic in the annealed condition.

Which is better ss410 or ss316?

316 vs 410 stainless steel tensile strength The yield strength of 316 stainless steel is 230-850, while that of 410 stainless steel is 290-580. 316 stainless steel can be used in a wider range of fields, while 410 stainless steel has higher stress, suitable for some specific strength occasions.

What is the difference between 347 and 347H?

347 contains no more 0.08% carbon while 347H stainless steel contains between 0.04% and 0.10% carbon. Both contain between 17.0% and 20.0% chromium, and no more than 2.0% manganese. 347 stainless steel plate contains at most 0.04% phosphorous while 347H stainless steel can only contain up to 0.03% phosphorous.

How do you weld 347 stainless steel?

Type 347 may be welded by shielded fusion and resistance welding operations. Austenitic stainless steel welds do not harden on cooling, hence the welds will show good toughness. Oxyacetylene welding is not recommended due to the possibility of carbon pick up in the weld area.

Can duplex stainless steel be hardened?

Duplex stainless steels cannot be hardened by heat treatment. They can however be work hardened. Solution treatment or annealing can be done by rapid cooling after heating to around 1100°C.

Can you arc weld stainless?

Stainless steel can be welded with shielded metal arc welding (MIG), gas tungsten arc welding (TIG) and stick welding, and each of these processes will yield a slightly different result.

What is the difference between AISI 321 stainless steel and 347 stainless steel?

Both AISI 321 stainless steel and AISI 347 stainless steel are iron alloys. Their average alloy composition is basically identical. There are 33 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

What is the machinability rating of 321 stainless steel?

Grade 321 stainless steel machinability is 36% in annealed conditoin based on a machinability rating of 100% for 1212 steel.

What is the difference between alloy 321 and alloy 347?

Alloy 347 also performs somewhat better than Alloy 321 in strongly oxidizing environments up to 1500°F (816°C). The alloy can be used in nitric solutions, most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10% diluted solutions at elevated temperatures.

What is Type 321 used for in welding?

Type 321, 321H and TP321 can be used in places where solution treatment after welding is not possible, such as steam lines and superheater pipes and exhaust systems in reciprocating engines and gas turbines with temperatures ranging from 425 to 870 °C (800 to 1600 °F).
