Stainless Steel Types Commonly Used

*Stainless Steel 304(1.4308)

This is the most common stainless steel and is applied in different applications. It consists of at least 18% chromium and 8% nickel and has no magnetic properties within its austenitic structure.

*Stainless Steel 304L(1.4309)

Corresponds to stainless steel 304. The‘L’stands for‘low carbon’, so this stainless steel has a lower carbon amount to increase weldability and to limit the corrosion sensitivity after welding.

*Stainless Steel 316(1.4408)

A better, but more expensive type of corrosion resistant steel is stainless steel 316. This alloy contains at least 16% chromium, 10% nickel and 2% molybdenum. Because of the addition of molybdenum, this stainless steel type is better defended against salt corrosion and acids, and is often applied in chemical industries.

*Stainless Steel 316L(1.4409)

Comparable to stainless steel 316 but with a lower carbon level to increase weldability of the stainless steel.

*17-4 PH(1.4549)

A high quality stainless steel which is regularly used in the aircraft industry. It is characterized by a high tensile strength, hardness, toughness and is also corrosion resistant.
