What is the chemical properties of stainless steel?

Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.

What are the useful properties of stainless steel?

Do you need to weld 304 grade stainless steel?

Welding of AISI 304 Grade Stainless Steel. Type 304 stainless steel has excellent weldability and does not require preheating. Generally, post-weld heat treatment is not required, unless large cross-sections are welded, or weld decay may occor.

What should the temperature be for AISI 304 stainless steel?

The following contents give AISI 304 grade stainless steel heat treatment temperature of including annealing, forging, stress relief, etc. Recommended annealing temperature for austenitic stainless steel 304: 1040 °C (1900 °F). Typical forging temperature range is 925-1260 °C (1700-2300 °F).

What kind of filler is used for 304 stainless steel?

Filler metal for welding of AISI 304 stainless steel: E308, E309. When the service temperature is 370 °C (700 °F), E308L can be used.
