Can you heat treat 304 stainless steel?

304 stainless steel cannot be hardened by heat treatment. Solution treatment or annealing can be done by rapid cooling after heating to 1010- 1120°C.

What is the annealing temperature for 304 stainless steel?

The curve below shows a typical S-N curve for 304 stainless steel. Annealing of types SS304 and SS304L is achieved by heating to above 1900°F and for 90 minutes per 25mm thickness followed by water or air quenching. The best corrosion resistance is achieved when the final annealing temperature is above 1900°F.

What temperature do you heat treat stainless steel?

Stress Relieving Austenitic stainless steels are typically heated between 800°F (425°C) and 1700°F (925°C) to achieve an adequate stress relief. One (1) hour at 1600°F (870°C) typically relieves about 85% of the residual stresses.

Which stainless steel can be hardened by heat treatment?

Martensitic stainless steels
Martensitic stainless steels can be hardened via heat treatment; how hard they can get depends on their carbon content. The more carbon these steels contain, the more hardenable they are. For example, hose clamp screws are typically made of 410 stainless steel.

How hard can 304 stainless steel get?

The stainless steel alloy material stands out with its incredible tensile strength of approximately 621 MPa or 90 KSI. Grade 304 also has a higher operating temperature of up to 870 °C.

How do you anneal 304 stainless steel?

Annealing of types SS304 and SS304L is achieved by heating to above 1900°F and for 90 minutes per 25mm thickness followed by water or air quenching. The best corrosion resistance is achieved when the final annealing temperature is above 1900°F.

What is the allowable stress for stainless steel 304?

For all forms except welded pipe and tubes, the maximum allowable stress for Type 304 at all temperatures below 100 F, according to Table UHA-23, is 18,750 psi. This same table allows a stress of 17,500 psi for Type 304L plate or seamless pipe or tubes.

Can you stress relieving 304 stainless steel?

1. The low-carbon grades (304L or 316L) or the stabilized grades (321 or 347) should not be at risk from corrosion sensitization during stress relief. Grades such as 304 or 316 are, therefore, processing in the temperature range of 900-1600ºF (480-870ºC) should be avoided.

Can you heat treat 316 stainless steel?

HEAT TREATING 316/316L is not hardenable by heat treatment. Cold working increases tensile strength and hardness. Annealing range is between 1850 and 2050F.

Can 316 stainless steel be heat treated?
